USING FABRICS TO THE FULL. THE USE OF POLYMERIC FABRICS IN CIVIL ENGINEERING

The article examines the development of impermeable and permeable fabric materials for a range of applications in civil engineering. For linings of reservoirs and canals the chemical resistance of butyl rubber or polyolefin materials offers a cost-benefit advantage over polyethylene and pvc materials which, although cheaper, need protection against abrasion, ultraviolet light and ozone to avoid degradation. In reinforced earth applications polyethylene tapes anchored to butyl rubber form the body of the structure while glass-fibre panelling is attached to the irregular face of the reinforced earth. The most common use for permeable fabric is for interceptor or cut-off drains set vertically in a slit trench. The introduction of permeable fabrics into road construction, for temporary as well as permanent constructions, offers instant stability for soft subgrade materials. /TRRL/
