Geotextile membranes are often used to prevent surface dressings from disappearing into the sub-grade layer. This material is used for separation purposes underneath driveways, patios and pathways.


If you want to prevent land drainage systems from clogging, geotextile membranes can be used to create a water-permeable barrier. This barrier will prevent fine rocks and silt from passing through whilst allowing free movement of water.


Geotextile membranes are often used when constructing banks to help prevent lateral movement of the fill layers and stabilise the bank. This is done by laying a layer of fill material followed by a layer of membrane, and repeating this process until the bank is at the correct height.
