FAQ

Waterproofing inspections in Aintree: common questions

Why does the tape on joins matter?

If the tape fails or is missing, water can run behind the tiles and into the wall cavity.

What is wrong with short upturns?

Water runs down the wall and pools at the floor edge. This eventually causes the tiles to lift.

What does a screed fall issue mean?

It means the floor is not sloped correctly towards the drain. Water will not drain away properly.

Which standard applies here?

AS 3740 covers waterproofing of domestic wet areas, with compliance against the NCC.

Is the plumbing flood tested?

No. A flood test is work that belongs to the waterproofer.

Who fixes these defects?

The waterproofer must make the repairs before the tiler proceeds.
