Why Cavity Drainage ?

We propose cavity drainage for the following reasons: •The installation of a cavity drain membrane system does not increase hydrostatic pressure against the structure of the building. •Easier preparation-no need to grit blast to remove paint or bush hammer to form a key to the substrate or open up the pores of the concrete. •Less wet trades are used and less dust is created. •When used with dry lining systems and chipboard finishes they give improved insulation performance thereby helping to reduce problems with condensation and lower heating costs. •Easier and more flexible locating of electrical and plumbing services. •One of the most reliable internal waterproofing systems-BS8102 •Quick drying to enable redecoration to be carried out sooner. •Greatly improved ability to withstand structural movement and vibration. •Can be used over different substrates without the need for specialist jointing systems. •Can be used on contaminated surfaces. •A wider range of decorative finishes can be applied. •Proven long term performance. •Does not involve the use of chemicals associated with COSHH (Control of Substances hazardous to Health) Regulations. •The membranes provide a water vapour barrier. •Quick, clean and sympathetic to the residents and the building structure.
