Black GTM100 Woven Geotextile Membrane 100gsm

Black GTM100 is a woven polypropylene geotextile membrane developed for domestic landscaping and garden applications where light stabilisation and weed control are required. At 100gsm, it sits above entry level weed control fabrics while remaining easy to handle and install on smaller sites.

In the ground, GTM100 works by separating the underlying soil from decorative aggregates or gravel layers. This helps reduce mixing, limits surface settlement and improves the long term appearance of garden paths, borders and seating areas. The woven structure also blocks light effectively, helping to suppress weed growth when fully covered.

Unlike non woven membranes, GTM100 is not designed for fine filtration or drainage control. It allows water to pass through but should not be used where soil fines need to be retained, such as on clay heavy ground or in drainage applications. It is best suited to firm, free draining soils where stabilisation and weed suppression are the primary requirements.

Typical uses include garden paths, decorative gravel areas, patios, shed bases and general landscaping projects. The membrane must always be buried and covered with aggregate, paving or soil. It is not suitable for use under driveways, trafficked areas or heavy load bearing applications.

GTM100 is supplied in practical, prepacked roll sizes that are easy to transport and install, making it a good option for DIY users and light landscaping work.
