New Membrane Installations & Remedial Solutions

Waterproofing membranes are a thin, water-resistant material that’s laid over a surface to protect against water leaks and damage.


Available in a liquid form or as a pre-formed sheet, we typically use sheet membranes for larger, flat spaces including rooftops, subfloors and commercial properties.


We take all forms of water damage and ingress seriously as we understand the risks when left untreated. Unless rectified with the right waterproofing, your building’s infrastructure will be severely compromised.


We install waterproofing for new builds, renovations, extensions and for remedial repairs. So, when you’re looking to keep the water out, be sure to contact us at Unique Waterproofing Solutions.
