Outside Wall Waterproofing

Masonry surfaces, such as exterior walls, are among the largest surface areas exposed to weather conditions such as rain, dust, UV rays and fungus.

Water tightness (Impermeability) of external walls is usually achieved by providing adequate wall thickness, waterproofing, proper design of construction joints, surface rendering and finishes, which serve as a barrier against water ingress.

If the exterior walls are not waterproofed, the invading moisture can cause damp walls, which are excellent breeding grounds for mildew and mold. This damages the walls and leads to health problems for the occupants.
