The MACLENNAN
Cavity Drain system
The cavity drain
membrane system required very little preparation and as it is
mechanically fixed and not designed to come under water pressure
bonding is not an issue.
The walls were dry lined and plastered by the main contractors
plastering team who had been trained in the plastering of membranes
by

basement every year but the inside of the cellar is unaffected.
Because the system was installed by
MACLENNAN

qualified company, the system is guaranteed for 10 years by the GPI
insurance scheme which is the only insured scheme available for
water proofing. The guarantee is renewable every 10 years if a
service agreement is entered into.
