Wastes & Flanges you can trust

Wastes and flanges are used to connect the waterproofing system to the plumbing drainage system. Without the use of wastes, flanges or a waterproofing membrane system, you may observe problems such as water leaking into your walls and ceilings, which can easily lead to major structural damage over time. Although, if not observed early enough, it can lead to consequential problems with mould growth in between insulation and cladding in your ceiling cavity, resulting in poor insulation and high heating costs.

Puddle flanges are designed with a distinctive process that guarantees a watertight seal around concrete wall pipe seams, intercepting them from bursting. Puddle flanges are obtainable for both tiled and vinyl floors in order to suit the needs of several floor waterproofing installation techniques.
