Remediation works on the Kennet and Avon Canal
Gardiners recently carried out works for the Canal and River Trust to remediate an old brick flume, taking overflow water from the canal, under a railway line and into the River Avon.
As the original brick flume was in need of substantial repair, a more suitable solution was sought in the form of Concrete Canvas® GCCM, which is a cement impregnated geotextile that hardens on hydration to form a durable, fibre reinforced, impermeable concrete layer. The material can be deployed by hand from portable batched rolls or from large bulk rolls mounted on spreader beam equipment for larger projects and where plant is available. CC can be cut to the exact section of any given channel, eliminating waste and accommodating variations in profile. The main advantages over conventional concrete are speed and ease of install, cost savings, durability and environmental friendliness.
Given the restricted access, CC8™ batched rolls were the chosen solution. Access to the site was via a steep slope of around 40 degrees and through a set of wooden steps. Water was diverted via temporary pipes and existing bricks were jet washed. Large voids were grout repaired prior to laying the CC.
After this preparation, 40m² of CC8™ was installed in just one day by two of our operatives.
