Waterproofing creates a barrier

Waterproofing is the process where a building component is made totally resistant to the passage of water flow or water vapour. It creates a barrier which prevents the flow of moisture through porous materials such as concrete,brickwork and masonry. This process is only achieved when using a membrane coating which makes the surface waterproof.
DampShield specialises in the waterproofing of all wet areas in Residential, Commercial and Industrial properties. The work is fully Guaranteed and carried out by Licensed and experienced tradesmen to comply with Australian Standards.


Waterproofing areas include:

  • walls
  • bathrooms
  • balconies
  • laundries
  • concrete surfaces and slabs
  • sub-tile areas
  • planter boxes
  • sandstone facingswaterproof membrane coatings
  • roofs
  • decks
  • retaining walls
  • cavity flashings
  • basements
  • drainage areas

Waterproof membranes are applied to the positive side of the wall also known as the side of the wall in which water is penetrating. In circumstances where the positive side is denied such as basements, areas of high soil build up (which cannot be moved) and common walls (where the neighbour denies access), a tanking solution is applied instead of a waterproof membrane.

As demonstrated in the top photo, the external or positive side of the building had become porous allowing water to penetrate to the internal living area.

The bottom photo shows the finished membrane coating following wall preparation including removal of old paint, patching of the render surface and the reinforcement of cracks. The wall is then sealed before 2 coats of UV stable membrane is applied.
