Installation Guides

Silt Mats™ are biodegradable geotextile products designed to capture sediment and silt carried by surface water runoff. They help prevent pollution by filtering out fine particles before they enter drains, watercourses, or the wider environment.

Silt Mats are ideal for use during groundworks, excavation, stockpiling, or any activity that disturbs soil and risks waterborne sediment runoff. They’re especially useful near site perimeters, drainage outfalls, or temporary haul roads.

Yes –  in fact, we often recommend using Silt Mats as part of a layered approach alongside our product range for enhanced performance. Contact us to discuss site specific solutions with our Technical Team.

Silt Mats typically last between two and six months in active use, depending on exposure, water flow, and sediment load. They will biodegrade over time, but we recommend regular checks and replacement if signs of clogging or wear appear.

Installation is straightforward. Lay the mat flat on the surface or within the ditch, anchoring it  with sandbags, or stakes to keep it in place. Watch our installation video or download our CAD instructions for full guidance.

Our Silt Mats are engineered to cope with varying weather conditions, including heavy rainfall. Performance depends on correct installation and site conditions. In high-flow areas, combining mats with additional control measures may be necessary. Silt Mat must be properly weighted to withstand high flow conditions.

Yes, our mats are fully biodegradable and made from natural fibres. And are delivered nationally using a carbon neutral delivery service.

• In-ditch Polishing Point: consists of just Floc Mats, Silt Mats and Silt Wattles for a capturing and separating silt from flowing water. It is designed to ‘polish’ the water rather than our other treatment alternatives better designed for bulk drop out.
• In-ditch Treatment Point: includes the use of Gel Flocculant to bind fine silt particles to treat the water, as well as our mats which capture the suspended material while the surface water flows over them.

Maintenance is minimal but important. Inspect mats weekly or after heavy rainfall to ensure they are correctly positioned and not clogged. Replace if water clarity starts to decline.
