What Is Waterproofing?

Waterproofing is the application of a membrane, either liquid or sheet, to create a barrier preventing water transfer between wet areas and other structural components of a building such as framing or plasterboard in adjacent rooms.

Waterproofing is the second most expensive insurance claim, after fire damage to properties.  Ensuring a tight waterproof seal could save thousands of dollars of repair bills.


To ensure that tiles are installed correctly, please consider using a tiling professional. All Natural Stone and Encaustic tiles should be sealed immediately after install.


To ensure long lasting, beautiful tapware, please do not use any chemical based or harsh cleaners. Also avoid any rough surface materials such as scourers, only use a soft cloth with warm soapy water.
