Basement
Conversions - converting basements for Dry Storage or Habitable Rooms?
Cellar
waterproofing of newbuild or refurbishment of existing cellars?
Considering
tanking or waterproofing a basement?
It is possible
to turn a damp or even wet basement or cellar into a habitable room
or area used for dry storage, but it is imperative to know the correct
waterproofing membrane system to use.

Solution
Used:
The Newton
500 range of membrane products are used in all below ground waterproofing
applications. The Newton 500, Newton 500 Lath and Newton 520 membranes
are specifically designed for this environment.
WATERPROOFING BASEMENT
WALLS AND FLOORS:
The Newton 500 or Newton
500 Lath membrane would be applied to the walls either to give a waterproof
base for a dry-lined or rendered finish respectively. The Newton 500
(8mm cavity) or Newton 520 membrane (20mm cavity) would then be applied
to the floor to achieve a completely waterproof system. Drainage
products are used as appropriate to prevent the build-up of water
and pressure behind the membrane.
INTERNALLY APPLIED WATERPROOF
MEMBRANE INSTALLATION:
The success of the project
depends upon the understanding that BS8102 states that the design
of the drainage system should make allowance for water penetration
at some point in the future of the buildings life. A drainage
mechanism such as our our Newton
Titan range of pumps and Newton Basedrain
should be designed into the waterproofing system to prevent any water
pressure building up that if unchecked could lead to a sealed (tanking
only) system failing.
Internally applied systems
have the benefit that, should problems occur, the system is accessible
for remedial work unlike cementitious systems. Varying factors such
as external ground movement the location of the property, proximity
to underground streams and wells all have a bearing on the ultimate
design of the project. Companies specialising in this field who have
a greater understanding of the above should ideally be used. For a

BASEMENT WATERPROOFING
- NEWBUILD BASEMENTS:
Waterproofing a newbuild
basement using Newton Geo-drain:
The Newton
Geodrain membrane is laid to the blinding prior to the slab being
poured that goes above the membrane. Enough membrane is allowed for
to enable an effective join. The walls are formed by either concrete
block or poured concrete using shutters. Once cured and the wall is
complete, the Geodrain is fixed to the walls and joined to the Geodrain
on the floor. Additional Newton Geotex is wrapped around a perforated
pipe set in stone below the junction of the wall and floor. The pipe
must terminate to a discharge point.
