Damp Proof & Tanking

Pics For Website274
FacebookTwitterGoogle+Share

Dampness in buildings, if left untreated, can lead to structural deterioration; it will result in decay of timber, spoil decorations and can have problematic health effects through the development of moulds and mites. When an absorbent material such as paper, wood, cloth or brick is placed in a damp atmosphere it will absorb moisture. If the humidity changes the moisture content of the material will change with it. Richard Williams stock a variety of products suitable for damp proofing your house, cellar conversion, damp floor or salt contaminated walls.

Tanking

Our most popular tanking product is KA Tanking Slurry, which provides a solution to water leakage or seepage within your home. The formation and development of insoluble crystals into water bearing capillaries and fissures effectively blocks the further passage of water and ensures permanent water tightness for the life of the structure. It is designed to function against water penetration in various conditions. KA Tanking Slurry is supplied as a powder and when mixed with water, is applied directly to concrete, block work masonry or cement renders in areas where general waterproofing is required.

Damp Proofing

Our range of damp proofing products include DPC, Wykamol, Oldroyd P Membrane Kits and Cromapol.

Polythene Damp Proof Course (DPC) is designed to prevent the passage of moisture in brick and block work from external sources. DPC is manufactured from high quality reprocessed materials to provide a cost effective and durable domestic grade damp proof course. Alongside standard DPC, we also stock Hyload DPC, which is suitable for damp proofing and cavity trays in all solid/cavity wall applications (brick, block, stonework and concrete), it is resistant to compression even under the heaviest of wall loading and won’t extrude under load. Both types of DPC are available in a variety of widths.

Our Ultracure Damp Proofing Kits by Wykamol are also a popular product. Ultracure is a unique silicone emulsion cream for injection into the mortar course etc. for the control of rising damp. Unltracure can be used in all types of masonry without the use of high pressure equipment. The cream is delivered by hand pressure only from a simple displacement pump and injector lance into a series of holes drilled into the mortar course. From here it migrates rapidly into the masonry pores where the injection cream reverts to a liquid phase and polysiloxanes are formed in situ.

Visqueen

Our ever popular blue visqueen is a low-density polythene suitable for use in concrete floors not subject to hydrostatic pressure. It is ideal as a sandwich membrane in base concrete or between the base concrete and screed and has been accredited by the British Board of Agrement (BBA). We sell visqueen either by the metre (4 x 1mtr) or a full roll (4 x 25mtr).
