Treatments for rising damp

Rising damp occurs when a physical damp proof course breaks down, or there is simply no damp proof course in the wall. Ground water is then permitted to rise up the wall through capillary action, the water bringing building infill with it. The permanent damp state and infill react and form hygroscopic salts; the salts remain in the wall, rendering the masonry permanently damp.

To cure the contaminated wall, plaster is removed to a height above the last sign of dampness. The wall is salt neutralised if required. A chemical damp proof course is then injected at the base of the wall to prevent any more water from rising. An SBR slurry is then applied to the base of the wall to protect the exposed part and prevent any further damage to the skirting boards. The wall is then sand and cement rendered, water proofed and salt inhibited to block salts from travelling through. Finish plaster is then applied.

Treatments for penetrating damp

Penetrating damp occurs when exterior masonry becomes porous. Examples include defective pointing, damaged or ineffective rainwater goods, and cracks in the exterior render-work or porous brickwork.

To prevent water from penetrating the wall, action must be taken to correct the fault. These include re-pointing of walls, repair or replacement of water goods, sealing or replacing render or applying waterproof sealant to the wall. Internally contaminated plaster is removed, penetrating damp can track into adjacent walls. The wall is then salt neutralised if required. The wall is sand and cement rendered, waterproofed and salt inhibited. Thermal plaster boards are then installed if required. Finish plaster is then applied.

Treatments for flue salts

Flue salts appear on chimney breasts and are high in nitrate content. They are due to rainwater penetrating the flue or the flue being sealed allowing trapped moisture to condensate. The chimney is made water-tight and air flow supplied by vents. Plaster work is removed from the chimney breast, salt neutraliser is then applied due to the high salt content, the chimney breast is then sand and cement rendered, waterproofed and salt inhibited. Finish plaster is then applied.

All the above work is covered by a 20-year guarantee. Insurance-backed guarantees are available upon request.
