Concrete Canvas® (CC) is a flexible, concrete-filled geosynthetic, that hardens on hydration to form a thin, durable and waterproof concrete layer. Essentially, it’s Concrete on a Roll™. CC allows concrete construction without the need for plant or mixing equipment: just add water.
CC has been widely used by Network Rail across the UK for over ten years and is an industry-accepted alternative to conventional concrete. The geosynthetic has been specified by Route Directors, Senior Asset Engineers (Drainage) and minor works teams across the five Network Rail regions and their 13 routes.
CC has been extensively used through CP4, CP5 and CP6. The majority of route network framework contractors have installed CC including QTS, BAM Nuttall, Costain, AmcoGiffen, Alun Griffiths and Story Contracting.
Manufactured entirely in Wales, CC offers a lower carbon, environmentally sensitive solution for erosion control and weed suppression applications when compared to traditional concrete solutions.
