Lift Pit Waterproofing Services in Brisbane & Gold Coast
Specialist lift pit waterproofing solutions keeping lift shafts dry, safe, and fully functional using advanced negative-side techniques.
About Lift Pit Waterproofing
Lift pits are particularly vulnerable to water ingress due to their below-ground location and exposure to groundwater pressure. Water in lift pits can damage electrical systems, cause corrosion, create safety hazards, and violate building codes. Our negative-side waterproofing solutions are specifically designed for lift pits where external access is impossible, providing effective protection against groundwater seepage.
Benefits of Our Lift Pit Waterproofing Services

Negative-side waterproofing is applied from inside the lift pit, eliminating the need for costly and disruptive external excavation.

Our Lift Pit Waterproofing Process
We follow a systematic approach to ensure quality results and lasting protection for your property.
Assessment & Testing
We assess the pit construction, water sources, and ingress severity to develop an appropriate waterproofing strategy.
Surface Preparation
The lift pit surfaces are cleaned, cracks are chased out, and active leaks are temporarily controlled for membrane application.
Crack Injection
Active water leaks are sealed using polyurethane injection, creating a barrier against ongoing water pressure.
Membrane Application
A negative-side waterproofing membrane system is applied to walls and floor, creating a continuous waterproof barrier.
Protection & Finishing
Protective render or coating is applied over the membrane to provide mechanical protection and a professional finish.
Frequently Asked Questions
Common questions about our lift pit waterproofing services.
Why do lift pits leak?
Lift pits are below ground level and subject to hydrostatic pressure from groundwater. Leaks occur due to construction joints, cracks, deteriorated original waterproofing, or inadequate waterproofing during construction.
What is negative-side waterproofing?
Negative-side waterproofing is applied to the inside surface of a structure (the side opposite to water pressure). It uses specialised materials that can resist water pressure pushing from behind, ideal when external access is unavailable.
How long does lift pit waterproofing take?
Typical lift pit waterproofing takes 3-5 days depending on size and condition. We can stage works to minimise lift downtime in buildings with multiple lifts.
Will my lift be out of service during works?
The lift will need to be isolated during waterproofing works. We work efficiently to minimise downtime and can schedule works during low-use periods or in stages for multi-lift buildings.
