Geotextile membranes, also known as Terram membranes, are used for a variety of applications and are often an essential component of a landscape project. Geotextile membranes have three main functions: separation, filtration and reinforcement. Geotextile membranes may serve one or all of the aforementioned functions, depending on the circumstances.

Geotextile membranes used for separation purposes are primarily used to prevent surface dressings from disappearing into the underlying ground (sub-grade). For example, on a driveway where MOT Type 1 is used as a sub-base, a membrane may be used to prevent the MOT Type 1 from migrating downwards into the underlying ground if conditions required.

Geotextile membranes used for filtration purposes are often employed to prevent land drainage systems from clogging by creating a water-permeable barrier preventing fines and silt passing through but allowing free movement of water into the drainage channels.

Geotextile membranes used for reinforcement are often used when constructing banks where a layer of the fill material is laid followed by a layer of membrane. This process is repeated until the bank is the correct height. The membrane assists in preventing the lateral movement of the fill layers and helps to stabilise the bank.
