Barrier
Prevents or reduces the movement of any fluid through the use of a geosynthetic barrier. Used to isolate one material from another. Common applications are landfills or ponds to prevent contamination of surrounding areas.
What are the benefits of concrete canvas?
Concrete Canvas is a flexible, concrete impregnated fabric that hardens when hydrated to form a thin, durable, water proof and fire resistant concrete layer.
It is used for a wide range of erosion control and weed suppression applications, and allows concrete construction with minimal plant and specialist training.
Typically ten-times faster to install than conventional solutions, essentially its Concrete on a Roll: simply unroll and just add water.
Installation of Concrete Canvas is easy as it allows concrete construction without the need for plant or mixing equipment. Simply unroll and position Concrete Canvas and add water (any type of water, including sea water).
Provides more than 60% CO2e saving compared to conventional concrete solutions for erosion control applications in the UK.
Concrete Canvas is rapidly becoming the channel and ditch lining material of choice for engineers and contractors around the world. This product solution provides a hard-wearing erosion control surface for lining drainage and irrigation channels. Concrete Canvas is typically used as an alternative to conventional concrete drainage and where vegetated or earth lined ditches are unsuitable due to high flow rates, containment requirements or the need to reduce maintenance.
Concrete Canvas is significantly faster, easier and less expensive to install than conventional concrete channel lining and requires no specialist equipment. The matting can be laid at a rate of 200m² per hour by a 3 person team.
Concrete Canvas can be used to extend the durability of new culverts and upgrade existing structures by relining steel and concrete culverts, which have degraded due to scour and corrosion. This prevents the need for asset replacement and extends the life of culverts with improved impermeability and flow characteristics.
Concrete Canvas has been used worldwide as an effective method of preventing surface erosion and scour associated with water run-off from culverts outlets, spillways and over-toppings.
Concrete Canvas is increasingly being used as an alternative to non-structural shotcrete to protect slopes from surface erosion caused by weathering, surface run-off and environmental degradation. In certain applications Concrete Canvas can be used as structural slope stabilisation by combining it with steel mesh and soils nails.
Compared to shotcrete it is typically faster to install, more cost effective, requires less specialist plant equipment, and eliminates the risks associated with rebound and debris.
Concrete Canvas can be used for hard armour capping of earth bunds around petrochemical tank farms, munitions depots and flood defences. It is typically used to protect the bund from environmental degradation, animal damage improve impermeability and prevent weed growth.
Concrete Canvas ability to be installed quickly reduces time on site. The installation speed for bund lining is approximately 800 m2/day with a 6-man crew. Concrete Canvas Hydro may also be used in this application.
Concrete Canvas can be used as an alternative to brattice cloth, plaster board or concrete block-work to construct blast and vent wall structures for underground mining applications. Trials have shown that Concrete Canvas typically provides cost savings of over 20% compared to conventional solutions.
