Types of geotextile membranes

Also known as Terram membrane, a geotextile membrane is a type of protective fabric used in civil engineering and landscape projects. These are essential components when making driveways, land drains, paving, pathways and Equestrian arenas. Related: Geotextile membranes: your questions answered. What is geotextile membrane used for? Geotextile membrane has three main functions: filtration, separation and reinforcement. Filtration purposes. Geotextile membranes create a water-permeable barrier that prevents fine soil particles and silt from passing through whilst allowing free movement of water into the land drainage systems. This prevents drainage channels from clogging. Separation purposes. This protective fabric can also be used for soil separation to prevent surface aggregates from disappearing into the underlying sub-grade soil. For instance, on a patio where MOT Type 1 or MOT Type 3 is used as a sub-base, a geotextile membrane should be used to prevent the sub-base from sinking into the underlying ground. Reinforcement purposes. Membrane fabric helps prevent erosion as well as stabilise river banks and the banks of canals and ditches. This fabric is used for reinforcement when constructing river banks where a layer of the fill material is followed by a layer of geotextile membrane. This also helps prevent the lateral movement of the fill layers. Geotextile membranes can be used for one of these functions or all of them, depending on the situation. Types of geotextile membranes. At Mainland Aggregates, we supply a selection of Terram geotextile membrane, from non-woven geotextile membrane to woven geotextile membrane. Whether you are searching for geotextile membrane for driveways or geotextile membrane for soakaway, find the right membrane fabric online at Mainland Aggregates. Non-Woven Geotextile Membrane. Our non woven geotextile membrane is equivalent to Terram 1000. This thermally bonded geotextile can be used as a drainage filter and soil separator. This geo membrane is ideal for the following applications: - Permanent and temporary access roads as a firm base to place the crushed stone foundation layer. - Equestrian arenas as a separation between the sub-base layer and the riding surface. - Drainage trenches to prevent the fine soil particles from clogging the filter stone. It can also be used for pathways, driveways and paving. The non-woven geotextile membrane features non-slip properties that ensure that the surface grips the membrane for maximum traction. This membrane also allows water through whilst preventing soil particles from passing through. Our non-woven geotextile membrane should not be used for weed prevention. Woven Geotextile Membrane. Our general purpose geotextile membrane is a woven geotextile that can be used for separation and filtration purposes. The G90 membrane can be used for a variety of applications, including: - Equestrian arenas for separation purposes between the drainage layer and the sub-base layer. - Drainage trenches to prevent small soil particles from blocking the filter stone. - Access roads (both temporary and permanent) to create a firm base to place the crushed stone foundation layer. - Weed prevention in landscaping and garden applications. This geotextile weed membrane suppresses weeds while still allowing the passage of water. This woven geotextile membrane can also be used for root barriers, paving, pathways and driveways. We have two sizes available: Rolls of 2.25 x 100m (225m2) or 4.5 x 100m (450m2).
