WATERPROOFING

3.png

Safe, Practical Delivery

Many waterproofing projects take place on live commercial sites where access, safety and coordination are critical. APS combines experienced tradespeople, detailed planning and strong Health & Safety systems to deliver waterproofing works safely and efficiently, including projects requiring height access, staged works or complex site logistics.

We work with a range of waterproofing systems depending on the building type, substrate and environmental exposure. This includes membrane recoating, remedial waterproofing repairs, deck and balcony waterproofing, roof membrane replacement and preventative maintenance solutions designed to extend the life of existing systems.

Waterproofing Systems and types

2.png

Leak Detection & Assessments

Not all leaks are straightforward. Water can travel through cavities, membranes and building materials before becoming visible internally. Our team carries out detailed waterproofing investigations to identify likely failure points, assess existing systems and recommend practical repair or replacement options based on the condition of the building.

Our Approach

Waterproofing issues can cause serious damage if left unchecked, from internal leaks and membrane failure through to long-term structural deterioration.

Are you seeing signs of your waterproofing systems failing?

Wondering if you have a waterproofing issue?

Check out some common examples of waterproofing failure below.

ChatGPT Image May 10, 2026, 07_52_58 PM.png

01

Cracking, lifting or bubbling membranes

Visible movement, splitting or bubbling in the membrane can be a sign the system is deteriorating or losing adhesion.

ChatGPT Image May 10, 2026, 08_57_44 PM.png

02

Leaks or water stains appearing inside

Marks on ceilings, walls or around penetrations — especially during or after heavy rain — can indicate the waterproofing system is no longer performing as it should.

03

Ponding or standing water

Water that remains on the roof long after rain can place ongoing stress on the waterproofing system and often points to drainage or surface issues.

04

Signs of ageing or general deterioration

Older systems can become brittle, worn or damaged over time due to weather exposure, movement and general wear.

05

Damage around joins, edges or penetrations

Weak points around flashings, joints, vents and roof penetrations are common areas for waterproofing failure to begin.

06

Ongoing patch repairs

If the same areas continue to leak or require repeated repairs, the underlying issue may not have been fully resolved.

The process behind the system

Successful waterproofing relies on understanding the substrate, identifying failure points and applying the right system correctly.
