Using Groundtex Membrane with Resin Bound Surfaces

Is Groundtex compatible with resin bound surfaces?

Groundtex is designed as a base-layer fabric for resin bound installations. It is specifically manufactured to sit beneath Flowstone resin bound gravel and other resin bound systems, making it suitable for driveways, pathways and patios.

Rather than acting as a structural layer, the Groundtex woven membrane creates a clean separation between the prepared sub-base and the resin bound wearing course. For a complete compatible system, it can be paired with the Flowstone permeable floor kit.

What Groundtex does in the ground preparation

In a typical resin bound project, the membrane provides several practical benefits:

• Weed suppression — helps reduce weed growth through the finished surface, lowering ongoing maintenance.
• Ground stabilisation — contributes to a firmer, more even base beneath the resin bound layer.
• Separation — keeps the prepared ground and the resin bound finish separate during and after installation.

It is important to note that Groundtex is not a replacement for a properly compacted sub-base. The membrane should be laid over a suitable prepared foundation, with the resin bound system installed according to its own instructions.

When this matters

This is most relevant for exterior areas where weed growth or a slightly uneven base could affect the appearance and lifespan of a resin bound finish. If you are covering a driveway, footpath or patio, taking time to install the right geotextile layer can reduce the chance of weed-related disruption later.

Coverage is also worth checking before you order. The 2m x 10m roll provides approximately 20m², so measure the prepared area carefully and allow for a little extra at edges and overlaps.
