Cellar Tanking & Basement Waterproofing

Damp Protection Services Limited offer specialist advice to building owners, local authorities and various contractors. Damp Protection Services Limited have in-house experts that have extensive knowledge and experience in supplying and applying various cellar tanking systems.

The way that cellar and basement tanking systems work is by applying a waterproof tanking coating directly to the inside of any wall to prevent moisture from penetrating the property. This does not remove the water, it simply creates a barrier and is usually used in below ground level situations but also when a conventional damp proof system cannot be used.

We offer help, advice and guidance in connection with the various levels of waterproofing and cellar tanking as defined in BS8102:2009.

• Grade 1, Basic Utility – Some damp and seepage is tolerable. i.e. Plant rooms, underground Car Parks.
• Grade 2, Mid Utility – No penetrating water, ventilation may be required. i.e. Workshops, storage areas and electrical plant rooms.
• Grade 3, Habitable, Zero penetrating water, totally dry! i.e. Ventilated office and residential, restaurants and leisure facilities.

BS8102:2009 Outlines 3 different types of waterproofing methods we use:

Type A – a waterproof tanking  barrier coating either applied to the external or internal face of a building.
This is a cementitious coating that is applied to the walls to form a barrier against the ingress of water. This systems requires the brickwork of the house to be in a stable condition due to the fact that tanked walls need to resist the water pressure that will build up. In older houses, preparing walls can be quite time-consuming, involving hacking off old plaster, raking out old mortar, re-pointing and applying salt-neutralising products.

Type B – an integral tanking waterproofing system built into the fabric of a structure.
Watertight concrete tanking systems that can be integrated into the construction of a below ground structure.

Type C – a drained waterproofing tanking system.
This system involves a studded membrane, made from high-density polyethylene, being fixed to the walls with plugs. This allows water to flow down behind the membrane within the cavity created and to the floor and into a drainage system.

Damp Protection Services Limited offer a complete range of cellar tanking and basement waterproofing solutions available for all of the above requirements. Internal multi-layered cementitious tanking renders. External fully bonded cellar waterproofing sheet membrane and liquid applied systems.
