A Highly Visible Geotextile For Soil Separation & Contamination Control

This Hi-Vis Non-Woven Orange Geotextile is designed to provide a visible barrier between contaminated and clean soils. Its standout orange colour serves as a warning layer during future excavation work, while also helping to prevent the upward migration of pollutants through the soil profile.

Key Features

  • Clear visual indicator for contaminated ground

  • Separates clean and contaminated soil layers

  • Prevents mixing of adjacent soil materials

  • Quick to install and handle on site

  • Available in 4.5m x 100m rolls

  • Lightweight and easy to cut

Practical Applications

The membrane is typically used in brownfield developments, construction on ex-industrial land, and any project involving known or suspected contaminated soils. Its dual-purpose function provides:

  • A warning layer to alert future contractors during excavation

  • A separation barrier to maintain the integrity of clean fill or sub-base materials

Benefits

  • Contamination Control: Limits the migration of heavy metals, hydrocarbons and other pollutants into clean layers

  • Cost-Effective: Avoids full-site excavation by isolating affected zones

  • Time-Saving: Lightweight and easy to install with minimal training required

  • High Visibility: Supports HSE guidance for risk mitigation during groundworks

FAQs

What’s the difference between woven and non-woven geotextiles?

Woven geotextiles offer high tensile strength and are typically used for reinforcement, while non-woven variants like this one focus on separation and filtration with better permeability.

Can this membrane be used as a warning layer only?

Yes, its bright orange colour makes it ideal as a visual warning for contaminated land, even if there is no active containment required.

Is the membrane UV stable?

While short-term exposure is acceptable during installation, this product is intended for buried applications and is not UV-stabilised for prolonged surface exposure.

Does this meet construction industry standards?

Yes, all properties are tested to relevant EN ISO standards and suitable for use in most UK ground engineering applications.

Can I cut the membrane to size?

Absolutely – it’s easy to trim with a utility knife or shears to suit your trench or surface layout.
