CC Environmental Data
Concrete Canvas (CC) is the only way of laying a thin concrete layer 
from a prefabricated roll of material. This enables up to 150mm of 
poured concrete to be replaced with just 8mm for many surfacing 
applications. As a result, material saving of 95% can be achieved for
a typical construction project.
This directly reduces the CO2 footprint of construction work not only
through material savings but also through reduced road transport
and time on site.
CC traps dry concrete powder in a 3-dimensional fi bre matrix. Testing
based on BS8443 to indicate the effect of underwater setting, shows 
that CC loses only 3% by mass. By comparison, specialist underwater 
concretes typically lose between 10-15% whilst also requiring much 
larger volumes to be poured.
CC was approved for use by the Environment Agency (EA) Biodiversity 
team in 2010 for the Church Village Bypass Project. Benefi ts cited 
included ‘surface roughness to provide diversity in the channel’s 
morphology’ and its ability to introduce ‘sinuosity in the channel line’. 
Several projects have since been granted approval on a case-by-case 
basis and the EA recently purchased CC directly for internal use as a 
weed inhibitor.
Untreated CC will naturally ‘green’ over time as the textured top 
surface allows moss growth, whilst the fi bre-reinforced concrete layer
will prevent root-growing vegetation, which would otherwise restrict 
water fl ow and increase maintenance costs.
CC uses a specialist high early strength concrete with a limited alkaline 
reserve. Unlike most concretes, it is not classifi ed as an irritant and is 
less damaging to the environment.
