Liquid Membrane Waterproofing

Seamless liquid membrane waterproofing systems for commercial and residential applications — flat roofs, decks, balconies, and below-ground walls across New Zealand.

Liquid Membrane Waterproofing

Liquid membranes are seamless waterproofing coatings applied directly to a prepared substrate. Once cured, they form a fully bonded, flexible membrane that protects against water ingress while accommodating structural movement.

Unlike sheet membranes, liquid systems are installed in a continuous layer with no joins — reducing weak points and allowing for precise detailing around penetrations, upstands, and complex junctions.

Where Liquid Membranes Are Used

  • Flat and low-pitch roofs
  • Podium decks and balconies
  • Gutters and box gutters
  • External walls
  • Below-ground walls and retaining structures
  • Plant rooms and service areas

Key Advantages

  • Seamless application — no laps or joins, reducing potential leak points
  • Flexibility — accommodates substrate movement and thermal expansion
  • Effective for remedial works — ideal for repairs, detailing upgrades, and overlay systems
  • Recoat options — systems can be top-coated to extend service life and renew warranty

Technical Precision

Our certified coatings technicians follow strict substrate preparation, thickness control, and curing procedures to ensure system integrity. Every project is delivered with a focus on compliance, durability, and workmanship quality.
