CONCRETE ON A ROLL

Mirny Airport, in Yakutia, is the main means of transport for the Mirna Diamond Mine due to its remote location. A newly excavated drainage channel at the airport required lining to increase its design life and reduce future maintenance requirements.

There are just 3 months of the year when weather conditions allow to take place, so CC was the only possible solution.

1680m² of CC13 were installed in 3 days, compared to approx. 1 month for traditional solutions.

The remediation of a concrete wall overlooking Highway A41/IC24 in Porto was required due to severe erosion of the original sprayed concrete. Debris falling onto the road posed a risk to traffic.

CC was specified as it reduced disruption to traffic, required limited plant and specialist labour, and provided a faster installation.

130m² of CC5 were installed in just 6 hours by a team of four despite rain and difficult access.

The project was undertaken in an area of Cumbria which was damaged by Storm Desmond in December 2015.

The site had very limited access. The specified bulk and batched rolls of CC8 and CC13 had to be delivered via helicopter where use of the steep, narrow track was not possible.

Installation was carried out by the 7 5 Engineer Regiment on behalf of the Lake District National Park Authority.

In April 2015, SNCF used CC to line a channel located next to a railway line in Buzy, at the southern end of the Belair Tunnel.

A total of 250m² of CC8 were laid on damp soil, which would not have been possible with alternative solutions, in just 3.5 hours by 5 people.

Steep slopes at the Alcobendas Station in Madrid had been subject to erosion and instability issues, affecting the entrance to the station tunnel.

CC was laid down the slope, into a purpose-built runoff ditch to prevent water running onto the tracks.

2500m² of CC8 were installed in under a week - 70% quicker than shotcrete or gunite - without any interruption to train traffic.

A steep slope in Piazza Armerina in Enna, Sicily required temporary slope protection after a wall, built in the 1900s, collapsed.

CC was the only option for prevention of further collapse as the area is subject to very high temperatures in summer and high winds in winter.

400m² of CC5 were installed in 4 days by a team of three people, including two rock climbers, in temperatures of above 35°C.

CC was installed as an erosion prevention method for a gas pipeline in Abu Dhabi. By exposing the gas pipe, erosion threatened to damage infrastructure and the environment.

CC was specified due to its resistance to UV exposure and wildlife damage, and greater eco-friendliness compared to alternatives.

3000m² of CC5 were installed in 5 days on a remote site.

CC was used to line a series of drainage channels at the Onshore Processing Facility in Chayvo, Sakhalin for Exxon Neftgas Limited.

The client required a channel lining solution which could withstand the extreme cold temperatures experienced in the area in winter.

9250m² of CC8, and 5520m² of CC13 were installed in 3 weeks by a team of 6 people.

The Mooi River irrigation canal in Natal, South Africa, was badly cracked, resulting in significant water loss.

CC was specified to minimise interruption to water supply for residents, and because many areas of the canal could only be accessed on foot.

10,600m² of CC5 were installed by 12 people in temperatures of up to 36°C.

An outfall at the base of Mount Asama in Naganohara-town required lining in order to prevent further soil erosion as water was penetrating the slope, risking slip.

CC was specified due to its reduced logistical requirements, especially its rapid installation rate in inclement weather.

45m² of CC5 were installed by 4 people in just 3 hours in wet conditions.

CC was used to prevent rain water run-off infiltrating a gulley and causing a land slip at Wadi Laban, Riyadh, Saudi Arabia. CC was specified due to its quick installation times, and lower costs than traditional options.

After installation, the CC was painted to blend in with the surroundings.

750m² of CC8 were installed over a total of 27 hours, across 3 days.

A slope situated between a primary school and residential area, with a busy road running alongside, was at risk of slip due to high levels of rainfall and runoff. A solution was required to prevent a landslide.

CC was specified and over 1000m² of CC5^TM were installed in just 4 days with minimal disruption and no lane possession requirements.

The Brockman 4 mine in Western Australia, owned by Rio Tinto, required a slope protection solution at a Run of Mine. Surface water penetration prevention was required, as well as erosion control and weed suppression.

CC was selected due to its speed, ease of installation and cost-effectiveness.

A total of 810m² of CC5 were installed in 3 days by 3 people in temperatures of up to 43°C.

A section of bridge abutment, initially installed using a geogrid system, required erosion protection. CC was selected as it could be installed quickly, without specialist equipment and labour.

CC5 was specified and cut to length to fit the varying height of the wall, minimising wastage. 

The client was impressed with the ease of installation. 200m² were installed in just over 5 hours.

Willow Creek is a large open-pit mine in northeast British Columbia, producing both hard coking coal and low-volatile PCI coal for steelmaking. 

The channel had to be waterproof, capable of handling freeze-thaw conditions, and easy to repair.

Bulk rolls of CC8 and CC13 were fixed using screws and sealant to create watertight joints. The work was carried out in under six weeks on a remote site, in difficult weather conditions.

A channel at Pogo Mine, Alaska, was in need of remediation to prevent surface and storm water coming into contact with the adjacent mining tailings field.

CC was specified to remediate the existing, cracked shotcrete, damaged by freeze-thaw weathering, heavy rain and undermining.

The works were carried out in 11 days by a team of 6 in freezing temperatures, with a cost-saving of 90% compared to shotcrete.

The main objective of the installation in Sabang was to replace an existing damaged concrete lining on a slope.

CC8 was specified as it would not require any form works, heavy plant or specialist workers.

The CC was laid down the slope, jointed using Clearfix sealant and screws and fixed with steel pegs.

Urbanisation of the Industrial Park PIA Airport by AM Developers required a rainwater catchment area for infiltration.

The area in need of attention was a storm cistern, and the main aim was to prevent damage to the slopes caused by erosion.

CC5 was specified and laid vertically down the slopes over five days by a crew of 6-8 people.

CC was used as an erosion control measure on a slope adjacent to a section of the Zipaquira-Bogotá Highway in Chinchilla, Colombia.

The slope had suffered from slip and erosion due to adverse weather conditions and leakage from a water pipe on the slope. There was potential for falling debris to cause an accident on the highway or cycle path.

1000m² of CC5 were installed in 13 days in inclement weather by 6 people.

The fish reservoir in Aysen, Southern Chile, was previously lined with poured concrete, which had become cracked.

The solution needed to be impermeable, require minimal maintenance, and be less prone to cracking and erosion than the current lining method.

CC8 and CC13 were specified due to the material's ease of installation, longer lifespan, and erosion control properties.

The slope in Recife was located in a residential area and was facing severe erosion problems that had led to a house at the crest of the slope collapsing. CC had already been used on a trial basis within the municipality to assess its suitability.

The slope ranged between 5m-12m and was surrounded by housing. CC8 was specified for the works. 125m² of CC8 were carried out in just 9 hours by a team of six in temperatures of up to 35°C.

The Caserones project was a channel lining project located in the 3^rd Region of Atacama, 800km to the north of Santiago. The aim was to divert glacial melt water that threatened to flood a nearby copper mine.

A total of 53,200m² of CC5 were installed at an average rate of 230m²/hour, by two 6-man teams in a remote environment over 4,000m² above sea level and subject to temperatures ranging between -10°C to 20°C.
