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.

Geotextile membrane has three main functions: filtration, separation and reinforcement.
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.
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.
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.
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.
Our non woven geotextile membrane is equivalent to Terram . This thermally bonded geotextile can be used as a drainage filter and soil separator. This geo membrane is ideal for the following applications:
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.
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:
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).

Geotextile is a synthetic permeable textile material used to improve the soil characteristics. It has the ability to separate, filter, reinforce, protect and drain when used in association with soils. Geotextiles are ideal materials for many infrastructure works such as roads, harbors, landfills, drainage structures, and other civil projects.
Fig 1: Uses of Geotextile in various places.Geotextiles are made up of polymers such as polyester or polypropylene. They are divided into 3 categories on the basis of the way they are prepared :
1) Woven Fabric Geotextiles
2) Non-Woven Geotextiles
3) Knitted Geotextiles
Commonly found geotextiles are of the woven type and are manufactured by adopting the techniques which are similar to weaving usual clothing textiles. This type has the characteristic appearance of two sets of parallel threads or yarns. The yarn running along the length is called warp and the one perpendicular is called weft. (As shown in the figure below)
Fig 2: Woven Geotextile.Non-woven geotextiles are manufactured from either continuous filament yarn or short staple fiber. The bonding of fibers is done using thermal, chemical or mechanical techniques or a combination of techniques.
Fig 3: Non-Woven Geotextile.Geo-fibers obtained from mechanical interlocking or chemical or thermal bonding have a thickness of 0.5-1 mm while chemically bonded non-wovens are comparatively thick usually in the order of 3 mm.
Knitted geotextiles are manufactured by the process of interlocking a series of loops of yarn together. All of the knitted geosynthetics are formed by using the knitting technique in conjunction with some other method of geosynthetics manufacture, such as weaving.
Fig 4: Knitted Geotextile.Apart from these three geotextiles, other geosynthetics used are geonets, geogrids, geo-cells, geomembranes, geocomposites, etc. each having their own distinct features and uses for special applications.

The mode of operation of a geotextile in any application is defined by six discrete functions :
Fig 5: Functions of Geotextiles.The separation function of geotextile is majorly used in the construction of roads. Geotextile prevents the intermixing of two adjacent soils. For example, by separating fine subgrade soil from the aggregates of the base course, the geotextile preserves the drainage and the strength characteristics of the aggregate material.
Some of the applicable areas are:
The equilibrium of geotextile-to-soil system that allows for adequate liquid flow with limited soil loss across the plane of the geotextile. Porosity and permeability are the major properties of geotextiles which involve infiltration action.
A common application illustrating the filtration function is the use of a geotextile in a pavement edge drain, as shown in the figure above.
Introduction of geotextile in the soil increases the tensile strength of the soil the same amount steel does in concrete. The strength gain in soil due to the introduction of geotextile is by the following 3 mechanisms :
A layer of non-woven geotextile is impregnated in between existing and new asphalt layers. The geotextile absorbs asphalt to become a waterproofing membrane minimising vertical flow of water into the pavement structure.
The scope of geotextile in the engineering field is very vast. The application of geotextile is given under the heading of the nature of work.
Geotextiles are widely used in the construction of the road. It reinforces the soil by adding tensile strength to it. It is used as a rapid de-watering layer in the roadbed, the geotextiles need to preserve its permeability without losing its separating functions.
Fig 6: Use of Geotextile in road construction.The woven fabrics or the non-woven ones are used to separate the soil from the sub-soil without impeding the groundwater circulation where the ground is unstable. Enveloping individual layers with fabric prevents the material from wandering off sideways due to shocks and vibrations from running trains.
It is used for mud control. For the improvement of muddy paths and trails those used by cattle or light traffic, nonwoven fabrics are used and are folded by overlapping to include the pipe or a mass of grit.
The use of geotextiles to filter the soil and a more or less single size granular material to transport water is increasingly seen as a technically and commercially viable alternative to the conventional systems. Geotextiles perform the filtering mechanism for drainages in earth dams, in roads and highways, in reservoirs, behind retaining walls, deep drainage trenches, and agriculture.
Geotextiles protect river banks from erosion due to currents or lapping. When used in conjunction with natural or artificial enrockments, they act as a filter.
