Woven geotextile membranes are manufactured by weaving polypropylene tapes into a stable grid structure. This produces a membrane with high tensile strength and low elongation, suited to applications where ground stabilisation and load distribution are required rather than filtration.
These membranes are typically installed beneath driveways, access roads, car parks, patios and hard standings, particularly where the sub grade is weak or variable. By spreading imposed loads across a wider area, woven membranes help reduce rutting, settlement and long term deformation of the surface. They are also used in construction platforms, embankments and areas subject to repeated trafficking.
Woven membranes are permeable, allowing water to pass through the structure, but they are not designed to retain fine soil particles. Their role is stabilisation and separation, not drainage control. On clay, silt or fine soils, a non woven geotextile is often required alongside a woven membrane to provide effective filtration and prevent fines migration.
When fully buried, woven membranes also provide effective weed suppression by blocking light and limiting growth from below. This makes them suitable for long term installations where access for maintenance is limited and surface stability is critical.
Selecting the correct woven membrane depends on ground conditions, traffic levels and loading. Lighter grades are suitable for domestic driveways, paths and patios, while higher strength grades are used for commercial, industrial and civil engineering applications. Correct installation, including adequate overlaps and protection during aggregate placement, is essential to achieve the expected performance.
