Waterproof treatment for exposed balconies and decks to prevent water from penetrating into the structure or rooms below.
Roof Membrane Application
Installation of torch-on or liquid-applied waterproofing membranes for long-lasting protection on flat roof surfaces.

WARNING SIGNS
SIGNS YOUR PROPERTY
NEEDS WATERPROOFING
Waterproofing issues rarely resolve themselves. Look out for these warning signs and act before damage escalates:
Look out for: water stains or damp patches on ceilings or walls, blistering or bubbling paint on internal surfaces, mould or mildew growth inside the property, rising damp at wall bases, pooling water on flat roof surfaces, cracked or deteriorating waterproofing membrane, and any visible water entry after rain.
