Installation rates are typically much faster than traditional methods, with several thousand square metres installed in days or weeks rather than months. Faster installation reduces site disruption and helps assets return to service sooner.

Concrete Canvas^® can be used to line attenuation ponds, firewater lagoons, petrochemical containment lagoons, mining and process water lagoons, and decanting ponds. It is suitable for both new construction and remediation projects.

A Concrete Canvas lagoon lining significantly reduces maintenance by preventing vegetation growth, resisting root penetration and protecting underlying liners. The hard surface also minimises erosion and damage from maintenance traffic.

Joints are sealed using either thermal welding or sealed overlaps, depending on the product type. Welded joints can be air-pressure tested on site, ensuring joint integrity, strength and low permeability throughout the lagoon lining.

Yes. Unlike sprayed concrete, Concrete Canvas^® can be installed in wet or cold conditions and even sets underwater. This allows programmes to continue during adverse weather, reducing delays and overall project risk.

Concrete Canvas^® lagoon lining is designed for long-term durability, with independently verified design lives exceeding 120 years in erosion control applications. This makes them suitable for permanent or long-term containment infrastructure.

Concrete Canvas products are well suited to contaminated water lagoons, including those handling hydrocarbons, alkaline mine water and highway runoff. Its chemical resistance and low permeability help prevent harmful substances entering soil or groundwater.

Yes. Concrete Canvas^®,  CC Hydro^™ and CCX^® products can be installed directly over existing geomembranes or degraded liners, avoiding costly excavation and disposal. This approach maintains lagoon capacity while extending asset life and improving containment performance.

Concrete Canvas products provide a hard-armoured, concrete-lined surface combined with an impermeable layer, delivering containment, erosion resistance and puncture protection in a single system. This improves durability while significantly reducing installation time compared with traditional lining methods.

Lagoon lining is the installation of an impermeable barrier to prevent liquids from seeping into surrounding ground and groundwater. It is essential where lagoons are used to store contaminated runoff, petrochemicals, mine water or process by-products, helping operators meet environmental, safety and regulatory requirements.

Yes. CCX^® has been successfully used on infrastructure and public works projects across Europe, including highway attenuation ponds and treatment ponds, delivering reliable performance and measurable cost savings.

No. CCX^® can be installed by general civil engineering contractors using standard site equipment, reducing reliance on specialist trades and lowering overall project risk and cost.

CCX^® provides long-term protection against UV degradation, weathering, animal damage and abrasion during maintenance activities such as de-silting, helping extend the service life of geomembrane liners.

CCX^® installs significantly faster than traditional concrete solutions. Large membrane protection projects can be completed in days using small teams and minimal plant, reducing programme time and site disruption.

Yes. Because CCX^® forms a thin concrete layer, it maintains the original storage and flow capacity of ponds, lagoons and channels far better than soil, gravel or rip-rap protection systems.

CCX^® overlaps are thermally bonded using hot-wedge welding equipment to create a continuous, monolithic protective layer. This ensures structural continuity and long-term durability across the membrane surface.

Yes. CCX^® is specifically designed for installation on steep slopes without the need for shuttering, geocells or formwork. It can be laid vertically, making it ideal for lined ponds, channels and containment structures.

CCX^® replaces thick poured concrete layers with a thin, high-performance concrete mat typically 5–12mm thick. This reduces installation time, cost, carbon footprint and logistical complexity, while minimising the risk of damage to the underlying membrane.

CCX-U^® is suitable for protecting HDPE, LLDPE, PVC, EPDM rubber and Geosynthetic Clay Liners (GCLs). When used with GCLs, engineers should confirm that the confining stress provided during hydration meets manufacturer requirements.

CCX^® membrane protection is used to provide a durable concrete armour layer over geomembranes such as HDPE. It protects liners from mechanical damage, UV exposure, weathering, animals and maintenance activities while preserving the integrity of the containment system.

Yes. Concrete Canvas Ltd can supply small and large sample packs on request, which contain hardened swatches and unset A4 samples. Due to the volume of requests for sample packs, a
postage fee will apply.

The performance values of CC will start to decline once opened; the CC should, therefore, be used within a few days of opening to prevent any significant degradation. It is best practise to reseal any packaging after opening to extend this period as much as possible.

Concrete Canvas^® GCCM has nominal dry weights of 8kg/m², 12kg/m² and 19kg/m² for CCT1^®, CCT2^® and CCT3^® respectively.

Concrete Canvas^® is manufactured is three types; CCT1^®, CCT2^® and CCT3^® and CC Hydro^™ is manufactured in two types; CCHT1^™ and CCHT2^™. The types are used for different applications in accordance to ASTM D8364 – Standard Specification for GCCM Materials and different types may be required to suit site specific loading and erosion conditions.

Consult the construction drawings to verify if special substrate preparation measures such as substrate drainage details are needed.

It is recommended to begin at the downstream end of the culvert and work upstream.

If the designer confirms the corrugations are to be filled, this is typically carried out before installing the CC, by using a suitable rapid set, non-shrink grout.

Filling the corrugations ensures the material is properly supported, providing optimum durability and resistance to dynamic loading.

Anchor trench dimensions must be a minimum of 150mm x 150mm but may need to be increased to suit the designer’s requirements.

If the CC will be terminated in anchor trenches outside the culvert, excavate the leading and trailing edge anchor trenches into the soil at the inlet and outlet.

Large bolts or protrusions that may cause the CC to snag should be smoothed out using suitable concrete or grout.

Damage to the culvert (e.g. voids or pitting created by rust or corrosion) must be filled with concrete, grout or compacted gravel depending on the designer requirements.

Divert water (if lining an existing culvert). Remove vegetation, soil, gravel and any debris from pervious linings (such as loose bitumen coatings) to expose the corrugations in the culvert.

Concrete Canvas^® (CC) is the original Geosynthetic Cementitious Composite Mat (GCCM) and the first product to declare conformance to ASTM D8364 ‘Standard Specification for GCCMs’.

Concrete Canvas^® (CC) is the original Geosynthetic Cementitious Composite Mat (GCCM) and the first product to declare conformance to ASTM D8364 ‘Standard Specification for GCCMs’. It is a flexible, concrete filled geotextile that hardens on hydration to form a thin, durable and waterproof concrete layer. Essentially, it can be described as Concrete on a Roll^® and is used for a wide variety of applications including the lining of secondary containment bunds to provide erosion control, weed suppression, protecting against animal damage and reducing maintenance.

Spray the fibre surface multiple times until the CC is fully saturated. The wet CC will first darken and then become lighter as it absorbs the water.

CC can be cut using basic hand tools such as utility knives. Power tools such as disc cutters can also be used but will generate significant dust.

For end terminations of slopes, anchor trench shall be a minimum of 200mm x 200mm.

Anchor trenches are typically constructed at the Toe and Crest of slopes to provide a mechanical fixing restraining CC in the longitudinal direction.

Clean of vegetation including de-rooting and removal of sharp objects such as large stones and rocks >25mm. Grade to a uniform profile with all voids filled.

It should be noted that CC replaces conventional concrete for erosion control applications. CC shall not be used to provide a stabilisation/ retention function.

Note that CC will provide surface protection from external erosive forces such as from wind and rainfall.

CC is a flexible, concrete filled geotextile that hardens on hydration to form a thin, durable and waterproof concrete layer. Essentially, it can be described as Concrete on a Roll^® and is used for a wide variety of applications including the rapid lining of slopes to provide surface erosion protection and weed suppression.

To check proper hydration, the CC should feel wet to the touch several minutes after hydration. Press your thumb into the CC and release. If water is present in the depression in the CC, it has been sufficiently hydrated. If no water is observed, then more water must be applied.

Spray the fibre surface multiple times until the CC is fully saturated. The wet CC will first darken and then become lighter as it absorbs the water. Do not spray high pressure water directly onto the CC as this may wash a channel in the material.

Fold back top layer and hydrate the material under the overlapped sections of the CC. Apply a suitable sealant as an 8mm diameter continuous bead along the line of where the screws will be positioned. Fold the top layer back into position and insert stainless steel screws at 50mm centres, 30–50mm from the edge of the top layer so that the screw is inserted through the sealant bead.

Unroll CC on the channel profile to suit specified layup, ensuring the fibrous top surface faces upwards, with the PVC membrane in contact with the ground. This is achieved by dispensing the roll by naturally unrolling along the ground rather than pulling material from the top.

Consult the construction drawings to verify if special substrate preparation measures such as minimum bearing capacity requirements, installation of a non-woven geotextile, or if substrate drainage details are needed.

Anchor trench dimensions must be a minimum of 150mm x 150mm but may need to be increased to suit the designer’s requirements.

If the perimeter edge of the CC is terminating in a soil substrate (i.e. it is not going to be connected to existing infrastructure), excavate crest anchor trenches into the shoulders of the channel. Excavate Leading and Trailing edge anchor trenches on side slopes and along the invert.

It is a flexible, concrete filled geotextile that hardens on hydration to form a thin, durable and waterproof concrete layer. Essentially, it can be described as Concrete on a Roll^™ and is used for a wide variety of applications including the rapid lining of drainage channels, providing slope protection, weed suppression, culvert repair and general concrete remediation.

Remediation using CC or CCH offers:

• Significant cost savings compared to new builds

• Operational efficiency through rapid installation

• Environmental benefits, with reduced material use and waste

• Extended asset life and reduced lifecycle costs

Yes. Concrete Canvas can reline, resurface, and protect damaged concrete. It eliminates the need for extensive equipment and reduces future maintenance costs. For most remediation projects, CCT1^™ (5mm thick) is used to minimise capacity loss while still providing robust protection.

Concrete remediation refers to the repair, resurfacing, or refurbishment of existing concrete infrastructure to extend its service life. It is often more cost-effective and environmentally friendly than replacing structures with new-build solutions.

Concrete Canvas^® is fast to install, durable, cost-effective and eco-friendly, making it a trusted weed control solution across industries worldwide.

CC offers hydrocarbon resistance, preventing corrosion of pipework caused by vegetation growth. It also improves safety by ensuring clear visibility for leak detection along pipe tracks and bands.

Yes. Unlike poured or sprayed concrete, Concrete Canvas can be installed without rebound or overspray, meaning there’s no damage risk to nearby sensitive infrastructure.

Yes. Concrete Canvas^® has been tested for root penetration resistance under DD CEN/TS 14416:2005 and has proven effectiveness in suppressing invasive species like knotweed.

CC is used globally across sectors including rail, road, petrochemical, agriculture, public works, utilities and defence. It is particularly effective in limited-access areas such as railways, road verges and around pipe tracks.

In UK climates, Concrete Canvas^® has a minimum design life of 50 years for weed control and is BBA certified with a durability of over 120 years when used for erosion control applications.

Concrete Canvas^® is a Geosynthetic Cementitious Composite Mat (GCCM) that, once hydrated, forms a durable, fibre-reinforced concrete layer. This waterproof barrier prevents weed and vegetation growth, even for species that are notoriously difficult to control.

CCX-M^® typically replaces 100-150mm of poured, sprayed or precast concrete, resulting in typical material savings of 90%.This directly results in a reduction of the carbon footprint of construction works.

This is dependent on the application and the quality/ inclination of the substrate; as a guide, we recommend pegging in anchor trenches at 2m intervals and material overlaps (joints). In warm climate conditions, intermediate fixings are required at a maximum of 3m intervals on exposed CCX-M^® surfaces. Wind or hydraulic shear forces may also require pegging to prevent movement of the CCX^®. Consult the CC Specification Guide: Watercourses for more information or contact us below.

CCX^® can be installed vertically providing that the supporting surface is structurally stable. Contact Concrete Canvas Ltd for assessment of the intermediate fixings required to ensure the performance of the lining in steeply inclined applications.

There’s a reason why Concrete Canvas is used across a variety of sectors for its high-quality and durable erosion applications. Our unique properties and environmental benefits have established Concrete Canvas as a first-choice erosion control solution in many construction projects, including rail, road, public works and more.

Concrete Canvas is BBA certified with durability in excess of 120 years when used in erosion control applications.

The enhancement of impermeability of a CCX-M^® lined structure can be adjusted by selecting an appropriate method for joining the material. Please see the CCX^® Jointing Guide for more information.

The three most common methods for jointing CCX-M^™ are a screwed overlap joint; a screwed and sealed overlap joint; or a thermally bonded and screwed overlap joint. . Please see CCX^™ Jointing Guide or contact Concrete Canvas Ltd for more details.

CCX-U^® and CCX-M^® have been independently tested to the performance properties listed in ASTM D8364 – Standard Specification for GCCM Materials. Both products meet the minimum requirements of a Type II GCCM. Please see Technical Note 1 for more information on ASTM D8364.

CC drainage channels require minimal maintenance. Once the Concrete Canvas is installed as a concrete channel lining, it provides long-term protection and effective weed suppression that’s guaranteed to last for more than 120 years – in erosion control applications.

Yes, Concrete Canvas requires minimal ground preparation before it is applied. The unique design and materials of Concrete Canvas make it highly flexible, allowing it to conform to and accommodate existing concrete channels.

Typically, a drain depth is around 700mm below the soil surface to allow water to move over the drains. However, Concrete Canvas can be used in any drainage ditch with a greater or smaller depth.

Our team are experts in successfully installing CC drainage channels. Available in batched rolls, Concrete Canvas’ unique properties mean that it’s easy to install.

Watch our video to see the process of installing Concrete Canvas in drainage channels with four principles.

Concrete Canvas is used and trusted by clients from around the world. The unique materials mean that Concrete Canvas is used as an eco-friendly concrete drainage ditch solution to support a range of sectors and community projects.

Previously, Concrete Canvas has been used to line a concrete drainage channel at the side of the M32 motorway in Bristol, where a new bridge was designed and built for bus-only traffic. Concrete Canvas was chosen as an application to line an existing concrete channel for its easy and rapid installation with minimal disruption to traffic and its ability to be applied in wet conditions. In total, over 1,250m² of CCT2^™ was installed in under eight days by eight people in inclement weather, saving a significant amount of time, money and disruption to the project.

Read more about the types of projects that have benefited from using Concrete Canvas as a concrete channel and ditch lining.

• Five times as abrasion-resistant (as OPC Concrete)
• Cost-effective
• Easy installation
• Sustainable concrete channel solution
• Durable and long-lasting
• Suitable for a range of projects

There are many reasons why Concrete Canvas is used as a concrete drainage ditch or channel on existing land and construction sites.

Concrete channels by Concrete Canvas are a rapidly-installed concrete alternative to traditional concrete. Concrete channels prevent weed growth, silt generation and erosion, reducing maintenance requirements and costs. Available in batched, hand-portable rolls, CC can be installed for applications with limited access and comes ready to use – no mixing, measuring or compacting required. CC is BBA (British Board of Agreement) certified with durability in excess of 120 years when used in erosion
control applications.

CC drainage channel or ditch systems are five times as abrasion resistant as standard OPC concrete, have excellent chemical resistance, good weathering performance and will not degrade in UV.

Contact us to enquire about a CC cement drainage ditch for your project.

A concrete channel is a diversion channel or draining ditch that lets water flow in and out or convey clean water from one hillside to another.

Suitable for a range of infrastructures and sectors, Concrete Canvas offers effective and sustainable concrete channel drainage solutions for carrying surface water, increasing the protection of land development.

Concrete Canvas^® can be demolished using standard construction demolition equipment and disposed of in the same manner as conventional concrete waste. The EWC code for Concrete Canvas^® is 20 03 01.

Providing it is installed correctly, Concrete Canvas^® requires no regular post-installation maintenance.

Concrete Canvas^® should be installed with the fibrous surface exposed. The fibre reinforced concrete layer will protect the PVC backing from weathering and UV damage.

General PPE precautions should be taken; face masks, protective clothing and gloves should be worn when handling Concrete Canvas^®. Concrete Canvas^® does not contain measurable amounts of soluble chromium (VI) and is not classified as an irritant. Consult the CC & CCH (M)SDS document for more information.

Yes. When ordered in sufficient volumes, Concrete Canvas Ltd can accelerate or retard the setting times of Concrete Canvas^® to accommodate different environmental conditions and applications.

The minimum ratio of water: Concrete Canvas^® is 1:2 by weight. For Example, CC8 weighs 12kg/m² and a minimum of 6 litres/m² is required for hydration. Concrete Canvas^® cannot be over hydrated so an excess of water is always recommended.

Concrete Canvas^® can be hydrated using saline or non-saline water. The water does not need to be potable.

Yes. It will hydrate fully from immersion.

The Concrete Canvas^® will not reach its full strength and the setting time may be delayed.

One of the key features of Concrete Canvas^® is that the fixed internal volume and control during manufacture ensures void space is set within carefully prescribed bounds and subsequently limits the Water: Cement ratio achieved in the field. It is therefore not possible to over hydrate Concrete Canvas^®; it will set underwater and can, therefore, be installed in adverse weather conditions.

Before hydrating, unset Concrete Canvas^® can be cut using basic hand tools. It is recommended to use snap off disposable blades or handheld self-sharpening powered disc cutters. After CC has set, it can be cut using angle grinders, jigsaws with ceramic blades or good quality tile cutters.

Yes. Wherever possible it is advised to hydrate Concrete Canvas^® at dusk to avoid the water used for hydration evaporating in warm environments. In very hot conditions, it is advised to re-hydrate the material at 1-hour intervals for the first 5 hours.

Yes. Warm water should be used for hydration and plastic sheeting should then be applied over the hydrated material until it has set. Consult the CC & CC Hydro – Hydration Guide for further instruction or contact Concrete Canvas Ltd directly. Generally, the same setting conditions that apply to conventional concrete pouring should be observed when installing Concrete Canvas^®.

Yes. Once wet, Concrete Canvas^® has a working time of approximately 1-2 hours in a UK climate.

We do not recommend Concrete Canvas^® as a vehicle trackway in most circumstances. However, Concrete Canvas^® can be used as hard armour capping of ground to prevent dust generation, erosion and wash-out of fines. The load-bearing capacity of the trackway should be based on the surface modulus (CBR) of the ground which should be sufficient to support the requisite traffic loading. The Concrete Canvas^® should therefore only be used to provide surface erosion control rather than to increase the surface modulus of any given substrate. For this type of application, we would typically recommend 2 layers of CCT3^™ with an offset overlap and the 2 layers screwed together.  It is not recommended to install Concrete Canvas^® in turning areas where axle loading can ruck the surface of the material.

Concrete Canvas^® has excellent resistance to chemical attack, in particular sulphate attack, which means it is well suited for use in ground surfacing applications. The concrete we use is also much more resistant to chemical attack compared to ordinary Portland concrete. Concrete Canvas^® has passed acid (ph1), alkaline (ph13) and hydrocarbon immersion tests to BS14414.

Concrete Canvas^® has achieved Euroclass classification B-s1, d0 and has passed the American MSHA (Mine Safety and Health Administration) fire testing for use in underground mining applications.

Concrete Canvas^® uses a specialist high early strength cement with a limited alkaline reserve which is below the US Environmental Protection Agency limits. CC has been installed directly into live watercourses without the need for special environmental protection measures.

Yes. Concrete Canvas^® has been approved for use by the EA, SEPA and Natural Resources Wales on several projects. Case studies for these can be found on our website’s Project’s Page. Project approval is granted on a case-by-case basis.

Concrete Canvas^® typically replaces 100-150mm of poured, sprayed or precast concrete, resulting in typical material savings of 95%. This directly results in a reduction on the carbon footprint of construction works. A recent Life Cycle Assessment found that CC8^™ contains 45% of the embodied carbon when compared to a 150mm ST4 poured concrete channel before the transportation and installation carbon savings are also considered.

This is dependent on the application and the quality/ inclination of the substrate; as a guide, we recommend pegging in anchor trenches at 2m intervals and material overlaps (joints). In warm climate conditions, intermediate fixings are required at 3m intervals on exposed Concrete Canvas^® surfaces. Wind or Hydraulic shear forces may also require pegging to prevent movement of the Concrete Canvas^®. Consult the CC/CCH Installation Guide: Bund Lining and CC Hydraulic Design Guidance Notes documents for more information.

Concrete Canvas^® can be installed vertically providing that the supporting surface is structurally stable.

It depends on the application. Consult the application table in the CC User Guide: General or contact Concrete Canvas Ltd directly for technical advice.

The level of waterproofing that materials provide is typically referred to in geotechnics using a measure of permeability called the k-value. CC has been tested to BS1377 and has an average k value of between 10^-8 and 10^-9 m/s, which is similar to clay; a range commonly referred to as being impervious.

The permeability of a Concrete Canvas^® lined structure can be adjusted by selecting an appropriate method for joining the material. Please see the CC User Guide: Jointing and Fixing document for more information.

If the overall impermeability is critical for your application, we would recommend the use of our CC Hydro^™ material, which incorporates a high-performance containment geomembrane that is thermally welded with testable joints for quality assured containment applications. Please see the CC Hydro Brochure for more information.

The three most common methods are a screwed overlap joint; a screwed and sealed overlap joint; or a thermally bonded overlap joint. There are a number of other mechanical and non-mechanical methods which may be suitable for particular applications. Please see CC User Guide: Jointing & Fixing or contact Concrete Canvas Ltd for more details.

Slope protection is where the body of the slope is inherently stable but the surface of the slope is prone to erosion caused by weathering, surface run-off and environmental degradation. Concrete Canvas^® can be used for slope protection in this case.

Slope stabilisation is where the body of the slope is geotechnically unstable and is at risk of suffering from slip (where a mass of the slope collapses). In certain applications, Concrete Canvas^® can be used for structural slope stabilisation by combining it with flexible structural facings. In this case, the project should be designed by a geotechnical engineer. See CC Installation Guide: Slope Protection for more details.

Customers include UK and national rail, highways and environmental agencies, major mining companies and 8 of the top 10 oil and gas companies in the world.

The price of Concrete Canvas^® is volume dependant and the price/m² drops when ordering large volumes. Contact your local Concrete Canvas Ltd rep for a quote specific to your requirements and delivery location.

Yes. Concrete Canvas Ltd can supply small and large sample packs on request, which contain hardened swatches and unset A4 samples of each of the three material thicknesses. Due to the volume of requests for sample packs, a postage fee may apply.

CC Hydro^™ is available in standard bulk rolls only.

CC Hydro^™ is BBA certified with durability in excess of 50 years for the primary containment of non-pollutants and secondary containment of other liquids. For advice specific to your project, please contact Concrete Canvas Ltd.

CC Hydro^™ GCCB (CCH) is typically used to replace conventional liner systems for a wide range of containment applications. Typical examples include bund lining, lagoon lining, and tank lining and remediation. Our biggest markets for CCH are the Petrochemical and Oil & Gas sectors.

CC Hydro^™ (CCH) is the world’s first all-in-one armoured impermeable liner, known as a Geosynthetic Cementitious Composite Barrier. CC Hydro^™ (CCH) combines the concrete filled geosynthetic technology of Concrete Canvas^® with a highly impermeable, chemically resistant geomembrane liner. The liner incorporates a hi-visibility welding strip which allows joints to be thermally welded with a double-track or triple-track air channel for on-site testing.

Based on environmental exposure testing, CCX^® has a lifespan in excess of 50 years. For advice on specific climates, chemical conditions and applications please contact Concrete Canvas Ltd.

CCX^® is manufactured in our UK production plant using bespoke machinery designed by Concrete Canvas Ltd. The process uses a unique patented method of inserting a cementitious material between two geosynthetic layers and stitched together to form a GCCM. For some CCX^® product variants (discussed below), a LLDPE backing is applied to the bottom geotextile.

CCX-M^® is slightly stiffer than Concrete Canvas^®, making it more suitable for larger more uniform profiles. CCX-M^® has different drape characteristics than Concrete Canvas^®, making it less suitable for undulating surfaces.

CCX^® is unrolled into position and secured in place. The material is then hydrated. There is a 30-minute working window before setting begins, and in 24 hours the material hardens to in-service performance specifications.

CCX^® is part of a revolutionary new class of construction materials called Geosynthetic Cementitious Composite Mats (GCCMs). It is a flexible, concrete filled geosynthetic which hardens on hydration to form a thin, durable, waterproof and lower carbon alternative to conventional concrete. Essentially, it’s Concrete on a Roll^®.

Concrete Canvas^® is BBA certified with durability in excess of 120 years when used for erosion control applications. For advice on specific climates please contact Concrete Canvas Ltd.

Concrete Canvas^® is manufactured in our UK production plant using bespoke machinery designed by Concrete Canvas Ltd. A 3-dimensional synthetic fibre matrix is filled with a custom cement blend before a PVC coating is added to one side.

Concrete Canvas^® GCCM (CC) is typically used to replace conventional concrete for a wide range of erosion control and weed suppression applications. Typical examples include channel lining, slope protection, bund lining, remediation works, culvert lining, outfall protection, mining vent walls, gabion covering and pipe protection. Our biggest markets are the Civil Infrastructure (principally road and rail), Mining, Petrochemical and Agricultural sectors.
