Soluform have developed a range of
biodegradable and water soluble film bags for the placement of concrete in
rivers. The bags can be used on their own, or as liners to traditional
hessian/jute sand bags, to ensure cement fines are contained and not able to
leak out into the environment before the concrete has hardened. They have been
designed to offer an environmentally acceptable means of placing concrete in
Concrete filled hessian/jute bags (sand bags) have been used for decades to place concrete in rivers, for structuiral repairs, underpinning and scour protection works. The nature of the fabric bags however, meant that cement unavoidably leaked out and frequently polluted the watercourse. In the absence of extensive temporary works or dewatering, consent to use such a product within UK rivers is currently often difficult to obtain from either the Environment Agency or SEPA.
SoluForm's patented range of biodegradable or
water-soluble film liners have been designed to be placed inside traditional
hessian sand bags. The film liner creates an impermeable barrier that safely and
effectively contains the wet concrete and eliminates the risk of environmental
contamination, allowing the placement of concrete bagwork without the need for
dewatering. Once the block has hardened and the film is effectively redundant,
the bag will either safely biodegrade or dissolve, depending upon the type of
film bag, together with the biodegradable hessian bag.
SoluForm manufacture and distribute two forms of hessian bag liners; a biodegradable (potato) starch liner and a water-soluble pva liner. Our liners are supplied along with the hessian outer bags. We also provide suitable bag filling and bag closing devices, and training, if necessary........more.......
