Product Overview
1m x 10m geotextile filter membrane, manufactured from 80g/m² non-woven polypropylene fibres, covering 10m² per roll. Designed for drainage and soil separation, it allows water to flow freely while preventing fine soil particles from washing into drainage layers.
The fabric is commonly used in soakaways, French drains, and behind retaining walls, where it preserves the efficiency of the drainage system by stopping soil fines from clogging gravel or perforated pipes. Its non-woven structure balances permeability with particle retention, ensuring long-term stability in domestic and light civil applications.
Durable, rot-proof, and chemically inert, this compact roll size is ideal for narrow drainage trenches, small soakaways, or patch repairs to existing systems.
Features & Benefits
- Filtration: Permits water movement while preventing migration of fine soil particles.
- Drainage efficiency: Maintains performance of gravel layers and perforated pipes.
- Soil separation: Keeps soil and aggregate layers distinct, preserving structural stability.
- 80gsm non-woven construction: Balanced strength and permeability for domestic drainage.
- Durable polypropylene: Resistant to rot and unaffected by soil chemicals.
- Easy installation: Lightweight and easy to cut, handle, and position.
- Roll coverage: 1m x 10m (10m²), suited to small projects and repairs.
Applications
- Narrow trenches: Lines small drainage channels.
- Small soakaways: Prevents soil fines clogging aggregate.
- Drainage repairs: Useful for patching existing systems.
- Garden projects: Suited to small-scale landscaping drainage needs.
Installation Guidance
- Preparation: Excavate trenches or soakaway pits to design specifications.
- Positioning: Unroll fabric, laying flat against soil before backfilling with aggregate.
- Overlapping: Overlap sheets by at least 300mm to maintain continuous coverage.
- Wrapping: Fully encase drainage aggregate or soakaway crates where required.
- Covering: Ensure the fabric is completely enclosed by soil or aggregate to protect from UV.
