Structural waterproofing is used to protect a structure from rising or penetrating damp by the use of a physical barrier.
It can be used for:
• Party Walls
• Basement conversions
• Swimming pools
• Garage conversions (single skin)
• Installation of a wet room
• Properties built into a bank
• Bunds to fluid tanks in factories/farms
• Lining of concrete slurry tanks (agricultural use)
• Concrete floors where there is no membrane
• Areas of penetrating damp
As the term “structural waterproofing” includes a variety of systems, it is imperative that a survey is carried out by a qualified Damproofing or Structural Waterproofing surveyor, to ensure that the correct system is recommended and installed appropriately.
Most Common Types of Structural Waterproofing:
• Membranes. A preformed, mechanically fixed system that offers a range of designs for different areas. Uses a cavity drain system which re-directs water to a suitable outlet. Specific applications depending on the finish required.
• Cementitious. The use of cement based waterproofing slurries, usually multi-coat, including bitumous paints or epoxy coatings. These can be applied to clean concrete and masonry where the sub-structure is in good condition.
Drainage & Ventilation also play a vital role and must be considered as part of the structural waterproofing process.
