The MacLennan cavity drain system is an internal lining system which provides a cavity through which water will pass. The system consists of a profiled plastic wall membrane which drains to a plastic drainage channel (sited at the wall floor junction) and a profiled plastic floor membrane. Further to this sumps and pumps will also be required if natural drainage is not available. BS8102 requires that all waterproofing is maintainable and repairable. How do you comply with BS8102?
