Chemical Damp Proofing

Rising Damp can develop within ground floor walls due to the lack of an effective damp proof course or the omission of damp proofing during earlier construction. In most cases, rising damp is identified by a moisture line around the base of the walls just above skirting board level. In more severe cases of prolonged dampness, visible damp patches may appear along with hygroscopic salts on the wall surfaces. The result of this is damage to interior plaster and wall coverings. It should also be noted that recent findings by the asthma foundation concluded that damp rooms could increase the risk of developing asthma.

If left untreated it will rot any floor joists and other interior timber it comes into contact with, as well as causing more damage to the interior of the property. To remedy the problem a new DPC (damp proof course) will need to be installed. This is achieved by removing all plaster and backing coats back to the brickwork in the affected areas.

Drilling holes into the base of the wall and injecting Triton's "new generation" DPC formula. This is a water based and water soluble Thixotropic gel, which diffuses naturally into damp substrates. After injection, Tri-Gel reacts to form a water repellent silicone resin network within the capillaries of the substrate. This network is permeable to water vapour which means that the walls can "breathe" and dry out naturally. The formulation is not reliant on alkalinity for effective curing. Tri-Gel can be used effectively to treat brick, stone and other substrates.

Once the affected area has been injected waterproof sand and cement render is applied to the wall, followed with a plaster finish when the render has completely dried out.
