Basement Waterproofing

Waterproofing is usually required by building codes for structures that are built at or below ground level. Waterproofing and drainage considerations are especially important in cases where ground water is likely to build-up in the soil or where there is a high water table.

Water in the soil causes hydrostatic pressure to be exerted underneath basement floors and walls. This hydrostatic pressure can force water in through cracks, which can cause major structural damage as well as mould, decay and other moisture-related problems. BPQ has different methods to solve basement water ingress, each job is unique.

Structural Dampness

Structural dampness is the presence of unwanted moisture in the structure of a building, either the result of intrusion from outside or condensation from within the structure. A high proportion of damp problems in buildings are caused by condensation, rain penetration or rising damp.

Deck and Balcony Waterproofing

Waterproofing systems have become quite sophisticated and are a very specialized area. Failed waterproof decks, polymer or tile, are one of the leading causes of water damage to building structures and of personal injury when they fail. Where major problems occur in the construction industry is when improper products are used for the wrong application.

 For under-tile waterproofing products or exposed membrane systems, we have a waterproofing solution for your deck under construction or a leaking tiled balcony. We work only to the Master Builders standards for Internal and External Waterproofing. All products used comply with AS/NZ 4858:2004 and come with manufacturers warranties.

Crack Injection

 Hairline cracks in a concrete foundation are normal, but cracks that continue to widen spell trouble, we offer a lifetime warranty on all crack repairs. We offer both epoxy injection and polyurethane injection, and exterior crack repair solutions. Cracks in a poured concrete foundation which are diagonal or vertical and which are generally uniform in width, or which taper to an irregular hairline form and stop entirely, which are usually discontinuous in the crack's finest or hairline area (the crack "stops and starts" in the same area), are usually shrinkage cracks and should not be ongoing nor of structural significance, though they may invite water entry through the wall.

Rooftop Membrane

We are Working at Heights qualified and have all the safety equipment and experience to attend to waterproofing your rooftop. We have EWP (Elevated Work Platform) tickets so we can attack your job from any direction.
