In cases where embankments must be constructed over soft soils, or ground which may contain subterranean voids which are prone to subsidence there may be a requirement for high-strength geosynthetic reinforcement. Tensar’s Basetex range of high strength geotextiles is designed to offer the strength necessary to provide stability.
Made using a weft-insertion knitted process, the characteristic properties of Basetex enable the yarn to remain linear, so that they are able to reach their full tensile strength without the initial elongation associated with woven yarns. Polyester has excellent creep performance and high tensile modulus.
When correctly installed, Basetex can improve an embankment’s stability against deep seated failure planes and can thus be used to reduce or avoid staged construction and lead the project to remain on time and within budget. When any significant settlement cannot be allowed within a project, the embankment may need to be piled, in which case Basetex can be used to form a Tensioned Membrane Load Transfer Platform
. This will ensure that embankment loads are transmitted into the pile heads, which can be less costly and quicker than constructing a reinforced concrete raft. Over potential voids, such as in areas of mineworkings or those prone to dissolution features, Basetex can offer an early, safe warning of void development or a permanent solution.
