Building A New House
Apr 09, 2016 9:41 pm
Building with Dennis Homes for my first home and apologies for a few questions regarding water proofing but the regulation was a bit confusing to me
1.Is waterproofing a separate process for the bathroom or is placing tiles on the floor considered water proofing?
2. Also is this something that must be specifically mentioned in the contract or this is a Building regulation that is standard?
3.Lastly, the regulation says shower wall needs to be waterproofed to 180cm, and walls 15cm. Does "walls" mean the general wall area in the bathroom, so 15cm from the floor has to be waterproofed? Does this mean it has to be tiled or can you waterproof behind the plaster wall?
Sorry for some dumb questions but building is a completely new process.

Water proofing is a separate process to tiling. Tiling only provides a water resistant surface, tiling by itself is not a water proof finish.
Water proofing typically consists of painting the walls and floors with a rubbery type compound. The tiles go over the top of the water proofing. In addition there is a flexible bandage that does around all the wall/wall and wall/floor junctions.
(there is an exception when pre-manufactured fibreglass shower rooms are used)
Water proofing is called up in building regulations so it is not an option.
The water proofing compound is a bit like thick paint when it is applied. It needs to be stuck to something substantial, i.e. plaster board or cement sheets.
The water proofing should go in front of the plaster board to provide additional protection to the edges of the plasterboard.
The water proofing does not provide a very smooth finish so it is typically covered with a decorative finish such as tiles.
