Concrete Cloth (CC) is a flexible concrete material used to armor and protect earthen berms at oil refineries. CC hardens upon hydration to form a durable fiber-reinforced concrete layer preventing erosion from weathering. It can be rapidly installed by a small crew at over 3,000 square feet per day. CC conforms well to protrusions and corners, and allows installation in wet conditions, reducing delays from poor weather. It provides effective protection for sensitive infrastructure and prevents damage from animals or fires.

3. Erosion Protection Concrete Cloth (CC) – Technical Advantages
CC provides a hard armor surface protection preventing weathering erosion of the bund. CC is fiber
reinforced and has an abrasion resistance twice that of ordinary Portland cement.
Rapid Install
CC can be installed at rates of 3,000+ sf per day using a 6 man crew.
Weed Suppression
CC is an effective weed suppressant, reducing future maintenance costs associated with grass cutting of top
soils and negating the risk of fire from dried grasses.
Install in Wet Weather
Once hydrated, CC has a working time of 2 hours. This allows for installation in wet conditions
which reduces disruption due to inclement weather. When the weather was such that refurbishment
work on the berms isn’t possible, the contractors can switch to lining the already refurbished sections with
CC, meaning that there was a minimum delay in installation due to poor weather conditions.
Conformation to Protrusions
CC was able to conform to 90° turns, pipe protrusions through the bunds and terminations at buttress walls.

4. Erosion Protection Concrete Cloth (CC) – Technical Advantages
Protects Sensitive Infrastructure
The proximity of sensitive infrastructure meant that shotcreting or spray applied protective finishes were not
a feasible option at this site.
Prevents Animal Damage
CC preventing rodents from damaging underlying membranes and stopping burrowing animals from
compromising the integrity of the bund.
Fire Protection
CC can provide an additional level of fire protection in the event of catastrophic failure and subsequent ignition of
stored hydrocarbons.
Efficient Material Transportation
CC is very efficient in terms of material transport on truck can deliver 25,000+ (CC5) sf of material

9. Summary of Concrete Cloth (CC)
Concrete Canvas (CC) is a flexible concrete impregnated geotextile that hardens on hydration to form a thin, durable,
fiber reinforced concrete layer. Used predominately for above ground drainage applications, the material can also be
used for hard armor capping of earth berms around oil refinery tank farms
CC provides high level protection against degradation of earth bunds by preventing surface erosion from wind, rain
and freeze thaw. CC significantly extends the operational life span of berms, reducing through-life maintenance and
rebuild costs.
CC has excellent drape characteristics, allowing the material to conform in and around existing infrastructure, form
sealed joints around pipe protrusions and negotiate sharp bends and variations.
CC produces no back spray, eliminating problems associated with using sprayed concrete or resin based lining and
reinforcement systems around sensitive infrastructure.
CC Reduces maintenance and repair work by eliminating the risk of membrane or structural damage from burrowing
animals.
