Seamless, brush-applied waterproofing — no joints, no seams, no weak points. The system of choice for complex surfaces, wet areas and tight geometries.
Liquid membranes are applied in liquid form and cure to a seamless, fully adhered waterproofing layer — eliminating the seams and overlaps that create failure points in sheet systems.
Liquid membrane waterproofing systems are applied as a liquid coating — by brush, roller or spray — and cure to a flexible, fully adhered waterproofing layer. Because the system is applied in liquid form, it conforms completely to the substrate geometry: no cutting, folding, or overlapping required.
The absence of seams is the defining advantage. In sheet membrane systems, seams and overlaps are the primary failure point. Liquid membrane eliminates this vulnerability entirely — the cured membrane is a single continuous layer from edge to edge.
System advantages
Sheet membranes rely on seam integrity for their waterproofing performance. Liquid membranes have no seams — the cured layer is monolithic, with no preferential failure path for water to exploit.
Pipes, drains, steps, curved walls, tight angles — liquid membrane flows into and around any geometry. No heat welding or cutting required, making it the only practical system for many detailed areas.
Liquid membrane can often be applied over existing waterproofing systems in sound condition — making it a practical remedial option when full replacement is not warranted.
Applications
The seamless application is ideal for balconies — particularly those with complex drainage, upstands or architectural details that sheet membranes struggle to detail correctly.
NZ building code requires wet area waterproofing. Liquid membrane meets this requirement with a seamless, fully adhered layer that covers floors, walls and penetrations in a single system.
Liquid membrane is frequently used alongside sheet membrane systems — applied at penetrations, upstands and transitions where precise sealing is required before the main membrane is laid.

FAQ
Service life depends on the specific product, substrate condition and exposure. Most quality liquid membrane systems used in NZ are designed for 10–20 years. Wet area applications (bathrooms, showers) under tile typically exceed this when correctly installed on a clean, prepared substrate.
Yes — exterior-grade liquid membrane products are designed for full UV and weathering exposure. Product selection matters: not all liquid membranes are formulated for exposed exterior applications. We specify the correct product for each project's exposure conditions.
Liquid membranes are applied in multiple coats to achieve the specified dry film thickness. We use wet film gauges during application to verify coverage, and the final cured thickness determines the membrane's waterproofing performance and longevity.
Yes — liquid membrane is the standard wet area waterproofing system in NZ precisely because it can be tiled over once cured. The membrane provides the waterproofing layer; the tile provides the finished surface. Adhesion compatibility between the membrane and tile adhesive should always be confirmed.
