FAQ

Waterproofing inspections in Pakenham: common questions

What is wrong with membrane over the plug?

When the plug is pulled out at fit off, the membrane tears with it and leaves the outlet unsealed under the tiles.

What does a water stop do?

It stops water on the bathroom floor travelling under the door into the next room.

Why protect the membrane?

Boots, ladders and dropped tools puncture it, and a puncture under tiles is a leak.

Is this the same as the fixing stage?

No. Waterproofing is checked before tiling. Fixing comes later, once linings, doors and joinery are in.

How long does a waterproofing visit take?

Roughly an hour for two bathrooms and a laundry.

What standard applies?

AS 3740 for waterproofing of domestic wet areas and the NCC.
