Coffs Harbour Liquid Waterproofing Membrane

Liquid waterproofing membrane is one of the most versatile systems we offer at Bananacoast Waterproofing. Applied across Coffs Harbour, this flexible solution suits internal bathrooms, external balconies, rooftops, retaining walls and more. It forms a seamless layer that adapts to irregular surfaces, making it ideal for areas with multiple junctions, corners or penetrations.


  • Flexible membrane for complex surfaces
  • Seamless coverage with excellent adhesion
  • Works for both internal & external areas


Our team applies these systems with precision, ensuring correct film build and drying times for long-term performance. If you need a reliable membrane that moves with your structure, give us a call on 0412 065 525.

Ideal for Bathrooms, Decks & Rooftops

When traditional sheet membranes aren’t the best fit, liquid waterproofing fills the gap. It’s great for detailing around drains, wall joints, stairs and uneven surfaces. We use high-quality liquid products that cure into an elastic, water-resistant membrane, offering excellent durability in both sun-exposed and moisture-heavy environments.


  • Suitable for new builds & remedial works
  • Ideal for detailed internal & external areas
  • Applied by experienced, licensed installers


It’s a smart choice when flexibility, speed and full surface coverage matter. We’ll help you choose the right product based on site conditions and expected use.
