Yellow Directory - Water Proofing

Waterproofing is the formation of an impervious barrier, which is designed to prevent water entering or escaping from various sections of building structures. Internal areas that are waterproofed include bathrooms, shower recesses, laundries and toilets. Whilst external areas waterproofed extends to roofs, planter boxes, podiums, balconies, retaining walls and swimming pools.

Waterproofing can be applied to various substrates and backgrounds such as: concrete, cement render, fibre cement sheets, gypsum boards, and timber. Water, which enters or escapes from buildings, can have immediate and long-term undesired effects. Apart from damage to the buildings contents, structural damage is unavoidable if the problem persists. Water damage is second only to fire as a cause of building decay and deterioration. Furthermore, the Australian building systems appraisal council, ABSAC, a division of the CSIRO state that the majority of building materials have a considerable shorter life span when subjected to moisture or emersion over a prolonged period of time. The casualties of water damage include:

Rotting of timber structures and finishes such as floor joints, beams, floors, studs, skirting, architraves and frames.
Corrosion of metals such as steel reinforcement in concrete, steel beams, lintels, metal doorframes etc.
Swelling of plasterboards and the subsequent de-bonding of ceramic tiles.
Electrical hazards causing the possible short circuit of lighting and power points.
The blistering of paint.
Unsightly deterioration of the building facade.
Health problems due to dampness, which may lead to respiratory problems.
Rotting carpet.

The importance of waterproofing cannot be overstated. The damage caused to the building's structure, coupled with the high cost of rectification warrants the careful design and application of waterproofing.
