Frequently asked questions

  • What types of waterproofing do you provide?

    We offer comprehensive waterproofing solutions for roofs, balconies, floors, bathrooms, planter boxes and commercial applications. 

  • What commercial properties do you offer waterproofing for?

    Our licensed waterproofers travel across Castle Hill to install waterproofing membranes for factories, offices, schools, retail locations, restaurants, libraries and other commercial properties.  

  • What is a waterproofing membrane?

    A waterproofing membrane is a thin layer that’s installed onto a surface to prevent water leaks and damage. It typically consists of either a liquid that’s painted onto a surface or a pre-formed sheet. Waterproofing can be applied to foundational slabs, roofs, floors and even planter boxes

  • I have a flat roof and am concerned about water damage, what can you do?

    For flat commercial roofs we will generally apply a large, pre-formed sheet that’s tightly fitted to the surface. Flat roofs are particularly susceptible to water damage as heavy rainfall can cause the water to accumulate and pool on the roofs surface.
