Geotextile and Geogrid Products
Our geotextiles and geogrids improve drainage, reinforce the ground and help extend the lifespan of construction and drainage projects. Geotextile membranes are designed to be porous enough to allow filtration (6–30%) while retaining soil. They help facilitate effective drainage by preventing soil particles from entering drainage systems. Non-permeable membranes create a watertight barrier that prevents water from passing through.
Geogrids are a versatile solution that reinforce weak ground by locking aggregate into place, creating a stable foundation for roads, driveways, car parks and drainage systems.
Non-woven geotextiles are typically white and offer a higher level of permeability, making them ideal for lining land drains and soakaway crates to help reduce the risk of silt and debris causing blockages.

Geotextile & Geogrid Products FAQs
What is the Purpose of a Geotextile Membrane?
A geotextile membrane creates a separation layer between soil and aggregate while allowing water to pass through. This helps maintain effective drainage, reduce contamination and support the long-term stability of construction projects.
What is the Difference Between Woven and Non Woven Geotextile Membrane?
Woven geotextiles provide greater strength for ground stabilisation and separation, while non-woven geotextiles offer higher permeability, making them ideal for filtration and protecting drainage systems from silt.
What Considerations Are Needed When Choosing a Membrane for My Project?
Consider your ground conditions, drainage requirements and the membrane's intended purpose. If your project requires ground reinforcement, choose a woven geotextile. For improved filtration, choose a non-woven material.
What is the Difference Between a Geotextile Membrane and a Geogrid?
Geotextile membranes separate, filter or contain materials, while geogrids reinforce weak ground by stabilising aggregate. The right choice depends on whether your project requires drainage or ground reinforcement.
Which Industries Commonly Use Geotextiles and Geogrid Products?
Geotextiles and geogrids are widely used in construction, civil engineering, landscaping, highways, drainage, agriculture and rail projects. They’re designed to improve ground stability, separate different soil layers and allow water to drain without preventing soil loss, which is why they’re widely used in these sectors.
