Do I Need a Membrane Under Resin-Bound Driveways?

← Back to What Does Resin-Coated Tarpaulin Mean?

When laying a resin-bound driveway, the question of whether you need a membrane underneath is a common one. Installing the right underlay can make a noticeable difference in durability and appearance.

Why Use a Geotextile Membrane?

A geotextile membrane serves two main functions under resin-bound surfaces: it stabilises the sub-base and suppresses weeds. This creates a solid, even foundation, helping to prevent unsightly cracks and surface dips over time. By acting as a barrier, it also makes future maintenance much easier by reducing the chance of weeds breaking through.

Practical Guidance for Installation

Before installing your resin system, first prepare the sub-base — typically compacted MOT Type 1 or similar material. Lay a quality membrane, such as the Groundtex Woven Weed Membrane, ensuring it overlaps at the edges to avoid gaps. Secure it flat with fixing pins so it remains in place during the following stages, then add your resin-bound material on top. This ensures even coverage and maximum efficacy.

When a Membrane Matters Most

A membrane is especially valuable if your driveway is laid over earth, loose stone, or any base prone to movement and weed growth. For high-traffic areas or places with persistent weed problems, including a geotextile membrane can extend your driveway’s life and help it stay tidy with less maintenance.
