Mastic Asphalt Tanking ~ the objective of tanking is to provide a
continuous waterproof membrane which is applied to the base slab
and walls with complete continuity between the two applications.
The tanking can be applied externally or internally according
to the circumstances prevailing on site. Alternatives to mastic
asphalt are polythene sheeting: bituminous compounds: epoxy resin
compounds and bitumen laminates.External Mastic Asphalt Tanking ~ this is the preferred method
since it not only prevents the ingress of water it also protects the
main structure of the basement from aggressive sulphates which
may be present in the surrounding soil or ground water.Waterproofing Basements
