Flat roofing · Liquid waterproofing
Liquid resin roofs with no seams to fail
A cold-applied resin that cures into one continuous waterproof layer. Ideal for detailed roofs, terraces and refurbishments.
Overview
We are fully trained and approved installers of Westwood Liquid Technologies PMMA and PU liquid resin waterproofing systems. The resin is applied as a liquid and cures into a single seamless membrane, so there are no joins for water to find.
Because it is cold applied, there is no naked flame on site. That makes it a calm choice for occupied homes and buildings with lots of pipes, rooflights and awkward details.
Upgrading an existing flat roof? After assessing it, we can often apply the resin over the current covering with a new guarantee, sometimes without stripping the old roof at all.
Liquid systems resist UV and come in a range of colours and finishes. Anti-slip toppings make them suitable for walkways, terraces and balconies too.
