Effective Waterproofing Detail.

There are many potential causes of waterproofing failure. Most fall under four broad areas: Design and construction defects, incorrect preparation, application errors and incorrect product selection and inadequate protection.

The below photo indicates our recommended detailed preparation prior to the application of any membrane.

All showers are treated as Class 1 membrane regardless of construction materials used. The white substance in the photo is a 10mm backing rod held in position with silicone ensuring a true internal corner position. (After this stage we proceed with 50mm bond braking tape installation for bonded membranes.)

We use an engineered compound designed to level and smooth sub-floors with a minimum fall of 5mm. By doing this we ensure moisture flows to the drainage flange without ponding. This is done regardless of the drainage flange being set in or fixed to the top surface of floor substrate.

Accumulation of moisture, ponding results in breakdown of sub-standard or ill suited materials.

After the above detail has been undertaken continue with waterproofing of wet areas within residential buildings.
