TREATING
RISING DAMP

Diagnose

A diagnosis can be made by placing a Tramex Moisture Meter onto the affected wall. The reading of the meter indicates the amount of moisture present.

Prep

Applicators remove the original skirtings to be refitted at the end of the Chemical Dampproof Course work. The damp affected plaster is then removed to expose the brick or stone

Drill

A course of brick or stone is selected to become the new dampproof course. A series of 10mm holes are drilled at an appropriate depth and width.

Westox

The Westox chemical injection pump is then introduced and the injection lances are placed into the holes, a seal is formed by a rubber expansion washer which holds the lance firmly into the brick or stone. The injection is then pumped into the brickwork and the fluid forced under pressure into capillaries of the brick and stone until it is visually evident that saturation has taken place. The injection fluid continues to penetrate through the masonry and mortar joints by capillarity for approximately

24 hours and then gels.  

Dry & Done

After a drying period the walls are replastered using Westox Salt Retarder to complete the job. The new render is designed to allow the passage of water vapour, so that the residual moisture can dissipate from the wall to stop damp returning.
