Basement Waterproofing Perth

What is basement waterproofing? 

Below ground or basement waterproofing is an area that’s not often seen yet it’s an area of construction that’s usually neglected.  

Moisture is the biggest factor in the corrosion of reinforcing steel within concrete and, given enough back pressure, water can penetrate perfectly intact concrete.  Therefore, it’s crucial that the concrete be kept dry and protected in order to maintain the integrity of the structure itself. The solutions must be able to last the expected design life of the structure and longer.

Waterproofing is a requirement under the Building Code of Australia for structures that are built at, or below, ground level and are subject to ground water pressure.   If there is insufficient external drainage or a waterproofing failure, water will penetrate. All structures including residential homes, high rise commercial building and apartment buildings require basement waterproofing to prevent against water ingress.

In recent years there has been a dramatic increase in the construction of multi-storey buildings, commonly mixed-use and residential tower developments, in Australia. In these developments the basement structure is generally used as carparks, storage areas and utility areas and therefore require long term basement waterproofing solutions; it’s not commercially viable, or even possible in some cases, to upgrade or fix a failed waterproofing system in a basement of one of these structures.

What causes water ingress in below-ground basements?

Water ingress in below-ground basements result in damage that often take years to develop and may not always be visible.  However, over time there will be multiple signs of water damage that could lead to structural failure; these signs may include:

Cracks

The cracks may be vertical, horizontal, diagonal or stair-stepped and the widening of cracks indicate that water is putting pressure on the structure.

Odours

If your basement develops musty odours that cleaning, dehumidifiers and added ventilation do not remedy, then it’s a very good sign that there is a water leak.

Mould Growth

This fungus grows in damp dark areas and may cause respiratory problems over a long period of exposure.

Buckling Walls

The walls appear bowed inward and this is usually caused by hydrostatic pressure.

Efflorescence

This is a white, powdery residue that’s generally found on basement walls near the floor.

Peeling Paint

When water seeps through walls peeling (or bubbling) paint is evident along the basement walls.
