Waterpoofing For Garden, Decks and Flat Rooftops

Rapid Installation

ARDEX WPM is a versatile strong, continuous rubber membrane that can be heat welded. Single ply protection and fast hot air welded seams combine for rapid installation.


ARDEX WeldTec™ Waterproofing Membranes contain Impervashield technology, offering great flexibility and versatility combined with all the benefits of welded seams and quick application. With lower emissions during application, plus the fact they can be re-blended and therefore recycled, ARDEX WeldTec™ Waterproofing Membranes are the more eco-friendly choice.

We have been roofing with Butynol and related waterproof membranes for more than 20 years. We know what we’re doing and you can be sure of the highest quality job – every time. We are an approved Ardex waterproof membrane applicator, and known for being one of the top Butynol applicators in Auckland.
