FEATURES - Basement Tanking London
There are several methods on the market that ABS use in regards to basement tanking London, below is an explanation of two:
PASSIVE DRAINAGE SYSTEM
The Passive Drainage System is a tried and tested method of controlling moisture based
upon over 30 years of successful installations, by internally lining structures
that are subject to moisture ingress.
A cavity is created through which
free moisture can safely drain and across which capillary held moisture
cannot cross.
The 
system installation when applied to all floors and walls, will dramatically reduce the evaporation of ground water into the adjoining ground floor areas.
This method of moisture control meets the principals
of BS 8102 type C protection and has been fully explained, tested and
approved by the British Board of Agreement. (No other system has currently
met with their approval for the use in areas where free water may occur).
CEMENTITIOUS TANKING METHOD
The Cementitious Tanking System, is an alkali-resistant, synthetically
modified cement, 
which is mixed with styrene-butadiene and water, producing
a waterproof coating against both moisture and hydrostatic ground water.
The chemicals in the slurry react, penetrate and fill off or block the capillaries,
bonding onto the prepared surface.
The system is used for the positive and negative
waterproofing of below ground structures, such as cellars, underground car
parks, swimming pools, service tunnels, portable (drinking) water tanks,
garage inspection pits and lift shafts etc.
