Structural Waterproofing Systems
Waterproofing techniques are defined in BS8102, the British Standard for Protection of structures against water from the ground.
Members of the Property Care Association (PCA) must demonstrate an understanding of this standard and the Association code of practice for underground waterproofing. The PCA also requires that surveyors providing guidance on waterproofing must demonstrate their competence by gaining the Certificated Surveyor in Structural Waterproofing (CSSW) qualification.
The two types of waterproofing system commonly used in existing structures are.
Adhered waterproof membranes or type Awaterproofing systems (as defined in BS8102) are commonly multi coat renders, cement based coatings, bituminous paints or epoxy coatings. This form of waterproofing provides an unbroken barrier to water. These systems are applied to clean walls and floors and are usually protected and held in place by floor screeds, renders, plasters or other loading coats.
Members of the PCA who specialise in structural waterproofing are able to consider the nature of the building and the clients design requirements to ensure that the correct method of waterproofing is selected and executed to the highest standard.
