Why use W.Tollett?
We use a chemical injection process which is low odour and cures to form a impervious barrier to rising damp. Adjacent abutting walls are isolated using a vertical damp proof course.
Used in conjunction with our specialist waterproof rendering system, the damp proof course provides a reliable, highly effective and cost effective method for the treatment of rising damp. Specialist replastering following the damp proof installation is essential.
The installed damp proof course prevents moisture rising into the walls, however, due to the effects of ground salts, the walls will not dry out effectively unless the existing wall plaster is removed and replaced using a salt retardant render.
What you need to know about damp proofing
Most modern buildings have some form of damp proof course barrier. This is to prevent water from getting into the brickwork. In older buildings all that was used to stop this was a piece of stone, when this fails it is best to insert a damp proof course. This is usually done with a cream which is inserted into the bricks which stops water from getting into the masonry.
Why you may need damp proofing
Rising damp is one of the most common causes of dampness in a building, it is caused by moisture being drawn up through porous bricks and mortar. Various forms of salt and chlorides are found in this moisture from the surrounding air when drying out. This provides an ideal growing ground for mould.
Installing Damp Courses
Rising damp can develop within 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 moisture readings obtained around the base of the walls. In more severe cases visible damp patches may appear, along with hydroscopic salts on the wall.
Typically, treatment involves the removal of skirting boards and plaster on the walls to approx. one metre high. Once our surveyor has carried out an inspection we will know the height of the necessary replastering, it can be as high as 1 metre. The damp proof course is installed in the wall by pattern drilling at the base of the wall and injecting a specially formulated injection liquid, until the entire depth of the wall is fully impregnated.
