In the building industry they say that waterproofing is 1.8% of construction costs, but accounts for a whopping 83% of building defect complaints! Waterproofing is an essential step in your construction process, as it ensures the longevity of your home by reducing the possibility of structural damage to your home. 

Evident signs of waterproofing failure can include,  Damp areas and fungi growth in adjoining rooms, swollen architraves and skirting boards, wet carpet with mould growth, fungal decay or staining, degradation of structural timbers and ceilings, strong musty odors, moisture droplets or staining to sub-floor timbers such as bearers and joists under or adjacent to wet areas, rising or penetrating damp in walls adjacent to wet areas, water seepage and more.

Water can permeate through incorrectly applied or damaged membranes and can also pass above and below a sound membrane that is not detailed correctly. To the untrained eye, a seemingly small issue could be masking a larger issue.

​It only takes the wrong product or the incorrect installation, due to the lack of knowledge and inexperience to damage and send the whole waterproofing project into disarray, that is why it's important that the waterproofing process should only be applied and carried out by a licensed, reputable, waterproofing professional who can complete the work to a quality standard. 


As with all waterproofing systems, the price should not be a determinable factor - as the lowest price does not always mean the best value. Consider the price you will pay for a failed waterproofing system at a later stage, when remediation work is involved to rectify the issue. Get the job done right without compromising on quality.
