Waterproofing / Cavity Waterproofing
Drainage
The cavity drain system would in the event of flooding rely on the effectiveness of your drainage to
remove water from the drainage channel.
You should have your drainage inspected and tested to ensure it can cope with any potential water ingress.
We would always recommend the installation of pumps so as in the event of a blockage in your drainage or
the drains generally being overwhelmed water ingression into your basement system can be safely pumped
away.

Finishes
A wide range of finishes can be adopted to walls, floors and soffits, which also provides protection to
the membrane system. Typical wall finishes include:-
A) Block work wall built in front of the system
B) Independent timber framing and plasterboard
C) Independent metal framing systems
D) Conventional plasters and renders:
Floors
E) Sand and cement screeds
F) Fast drying screeds with lightweight reinforcement
G) Wood-based sheets (tongue and groove flooring grade)
H) Timber boarding on floor beams
I) Sports floors
All the above finishes can be installed with insulation, where appropriate or specified.
Benefits
We would recommend the
MACLENNAN-LSE
WATERPROOFING Membrane system in preference to cement based, Bitumen, epoxy systems
or Waterproof concrete the benefits being:-.

Environment
Any building work in a basement or below ground area will produce water, which will condensate on cold
surfaces for a short period of time during and after the work.
The basement heating, ventilation and insulation should be designed to remove excess moisture vapour so
the basement has a comfortable environment free from condensation. Environmental control is not a part of
the water proofing design or installation.
