Sureproof Waterproofing Membrane — Heavy-Duty Protection for Basements & Below-Ground Walls

When you need guaranteed, long-term waterproofing, Sureproof is one of the most reliable systems available. It forms a tough, self-adhesive barrier around below-ground walls, protecting your property from water pressure, damp and structural damage.

To maximise performance, we also install a geotextile protection membrane over the Sureproof layer. This adds impact resistance, protects the waterproofing from backfill damage and helps manage ground moisture — giving you an even stronger, longer-lasting system.

Why homeowners and builders choose our Sureproof + Geotextile system

  • Creates a fully sealed, watertight barrier that stops water before it reaches your structure.
  • Geotextile layer protects the membrane from punctures and movement during backfilling, ensuring the waterproofing stays intact.
  • Resists ground water, salts and chemicals, ideal for basements, retaining walls and new builds.
  • Strong and flexible, able to cope with pressure and minor structural movement.
  • BBA-certified & BS 8102 compliant, providing total confidence in long-term protection.

The result

A dry, protected structure built to last. With the Sureproof membrane and geotextile covering working together, you get professional-grade waterproofing that stands up to real-world conditions for decades.
