Waterproofing Membrane Systems

The membrane is the barrier that actually keeps water out. Nova Tiling installs both liquid and sheet membrane systems, selecting the right approach for each wet area.

Quick Answer

What is a waterproofing membrane and which type is best?

A waterproofing membrane is the layer that stops water reaching the structure behind your tiles. Liquid membranes are applied in coats and conform to complex shapes and detailing, while sheet membranes are pre-formed for consistent thickness and fast, reliable coverage. The best choice depends on the area and detailing. Nova Tiling specifies and installs both across Auckland.

Who this is for

Anyone building or renovating a wet area — showers, bathrooms, balconies or decks — who needs dependable, correctly installed waterproofing beneath the tiles.

Overview

Tiles and grout are not waterproof on their own. The waterproofing membrane is the layer that genuinely protects the building structure, so getting it right is the single most important stage of any wet-area project.

Nova Tiling installs both liquid and sheet membrane systems. Liquid membranes are applied in coats and excel at complex detailing and penetrations; sheet membranes offer consistent thickness and fast coverage over larger, regular areas. The right system is chosen based on the area, detailing and conditions.

Liquid vs sheet membranes

Liquid membrane

Applied in coats; ideal for detailing, penetrations and irregular shapes.

Sheet membrane

Pre-formed; consistent thickness and fast, reliable coverage.

Performance

Correctly installed membranes protect the structure for the long term.

Reliability

Detailing at corners, joints and outlets is critical to success.

Appropriate applications

  • Showers, bathrooms and wet rooms
  • Laundries and other internal wet areas
  • Balconies, decks and exterior tiled areas
  • Areas with complex detailing and penetrations

Maintenance

Once tiled, the membrane is protected beneath the surface. Long-term performance is preserved by keeping grout and silicone joints sound, as these are the points where water could otherwise begin to reach the membrane.
