HighRise
Waterproofing

Membrane systems that keep water out and stay out — specified for the building, installed by licensed roofers and waterproofers, and documented for your insurer or body corporate.

What we do

Water gets in one way.
It has to be stopped there.

Most leaks aren't a mystery — they're a detail that was never finished properly. A penetration without a collar, an upstand that's too short, a lap rolled the wrong way. We start by finding the actual entry point rather than coating over the symptom.

From there we specify a full system — not a patch. That means the right membrane for the substrate and exposure, the correct falls and drainage, and every junction, upstand and penetration detailed to the manufacturer's spec so the warranty actually holds.

We're accredited applicators for Nuralite, Equus, RoofLogic, Ardex, Allco, GAF, Sika and Hitchins, so the system we install comes with manufacturer backing behind our own workmanship.
