The Basement in Bath Needed to be Watertight to BS Standards

March 18, 2010

For 100% peace of mind, our CSSW-qualified surveyor recommended the installation of a Cavity Drained Membrane System to the basement for maximum waterproofing and protection against ingress.

The British Standard identifies that a drained cavity system is the safest method available for those seeking maximum assurance against system failure. This is because ground water is controlled, diverted and harmlessly removed rather than being ‟blocked‟‟ at the point of entry. Consequently, the risk of increased Hydrostatic pressure is reduced, where directly applied systems generally increase the level of hydrostatic pressure imposed on the structure.

Because the basement is to be used for habitable space to the occupants, then the particular grade is 3. Performance at this grade, as specified by BS 8102:2009, assumes a dry environment. This means absolutely no dampness or water penetration is acceptable.

We specified and installed Newton Fibran XPS 500-C is a 50mm deep, closed-cell thermal insulation board made from rigid extruded polystyrene foam (XPS). The product is manufactured in accordance with EN 13164 – “Thermal insulation products for buildings – Factory made products of extruded polystyrene (XPS)-specification.”

Produced exclusively for Newton Waterproofing Ltd, Newton Fibran XPS 500-C insulation boards are used to form a 50mm spacer adjacent to the Basedrain and Floordrain drainage channels within the Newton System 500 cavity drain waterproofing system.
