The Cavity Drainage System
As one of the most sympathetic systems that can be applied to a structure, the cavity drainage system will not induce any additional stresses as a result of increased water pressure, protecting your home for you and your family. Our cavity drainage system is designed to control both water vapour and the penetration of ground water. This is achieved using a sealed system with pre-formed drainage channels that divert incoming water to a sump chamber. When it reaches the chamber, the water is then pumped to an external drainage point.
Containing complex colloidal silicates, the cementitious waterproofing additive swells in contact with water and blocks the capillaries and pores of sand/cement renders, screeds, and mortar to provide an effective barrier against the transmission of water. To help determine which method is best for your property, call CPM Waterproofing Services Ltd today for a free consultation.
