Environmental impact of installation
CC consists of a PVC backing, a three-dimensional fibre matrix at its core, and a polyester fibrous top surface. The specialist cementitious material is trapped within the 3D matrix which limits loss of material during the installation process.
As a result, CC can be installed and hydrated within live watercourses with minimal loss of fines at around 3% compared to the average of 10-15% experienced when using specialist underwater concretes (CC Environmental Data document).
CC uses a specialist high early strength concrete with a limited alkaline reserve. Unlike most concretes, it is not classed as an irritant, and the PVC backing is a high grade, phthalate-free compound chosen to minimise the product’s impact on the environment. As a result, CC can safely be installed on environmentally sensitive sites without any adverse effects on wildlife or the local ecology.
CC’s eco-friendly properties have led to its use on numerous sensitive sites and specification by several environmental agencies around the world, including public works projects for Environment Agency, National Resources Wales and Scottish Environmental Protection Agency in the UK.
