Durable Liquid Membrane Waterproofing for Complex Surfaces

Flexible, seamless protection for complex shapes, substrates, and detailing.

Precision-applied protection for challenging areas

Liquid-applied membranes offer unmatched versatility for areas requiring seamless, flexible coverage. At MPM Waterproofing, we specialise in applying liquid systems that create a fully bonded waterproof layer across irregular surfaces, junctions, and penetrations throughout Auckland and Northland.

Ideal for both new builds and re-waterproofing projects, these cold-applied membranes are fast-curing, UV-stable, and suitable for high-traffic or hard-to-access areas. Our team ensures expert surface preparation and product compatibility, backed by QA documentation and warranty support.

Whether waterproofing a balcony, sealing facade transitions, or restoring an ageing membrane, our systems are selected and applied with long-term performance in mind.

Balconies and decks

Suitable as a standalone waterproofing solution or overcoating existing membranes.

Facade and junction sealing

Integrates into cladding or facade systems as part of a full weatherproofing strategy.

Plant rooms and service areas

Durable under equipment, foot traffic, and regular maintenance access.

Remedial waterproofing

Used to extend the life of older membranes or replace failing waterproofing.

Our Process

  • We review the substrate condition, falls, detailing complexity, and UV and traffic exposure at your Auckland site to plan the correct liquid membrane approach before work begins.

  • We select a liquid membrane system compatible with the substrate, site conditions, and performance requirements. A detailed quote and scope of work will be provided before any work begins.

  • Surfaces are cleaned, repaired where needed, and primed to ensure strong adhesion, with all reinforcing fabric installed at critical junctions, outlets, and penetrations.

  • The membrane is applied in multiple coats using system-approved methods, with correct film thickness and curing intervals maintained throughout the application.

  • A final inspection is completed under MPM's QA framework. We provide site photos, PS3 producer statements, and warranty documentation on completion.
