A High-Visibility Woven Membrane For Separating Contaminated & Clean Soil Layers
This bright orange geotextile acts as both a physical separator and a visual warning marker during groundworks. It’s designed to identify and contain hazardous soils in land reclamation and other civil engineering projects.
Practical Applications & Benefits
Used widely in construction, brownfield development, and industrial remediation, this membrane prevents cross-contamination while helping future contractors spot buried hazards.
- Clearly identifies contaminated ground during future excavation
- Prevents upward migration of polluted soils
- Visibly separates contaminated and uncontaminated mineral layers
- Withstands site stresses thanks to woven polypropylene construction
- Resistant to soil acids, alkalis, bacteria, and fungi
- Predicted durability of 25+ years in standard conditions
- Lightweight and easy to install
Typical Applications
- Land remediation and brownfield redevelopment
- Civil engineering and construction projects
- Infrastructure and utility trenches
- Industrial decontamination sites

FAQs
What is this geotextile used for?
It’s designed to separate contaminated and clean soil layers while warning future excavators of hidden hazards.
Is this membrane UV resistant?
Yes. It contains UV inhibitors, making it suitable for short-term surface exposure prior to burial.
How do I install it?
Lay the membrane flat over the contaminated area, overlapping joints where necessary. It should be covered within two weeks of installation.
Can it be used with machinery traffic above?
Yes, it’s designed to handle moderate stress levels typical of civil site preparation.
What makes this better than a standard black membrane?
The orange colour provides an unmistakable warning marker, reducing health and safety risks during future digs.
