Damproofing and Tanking
Rising Dampness can develop within walls due to the lack of an effective damp proof course or the omission of damp proofing during earlier construction.
Rising dampness may be found during a Building Survey, by tests carried out to the base of the walls, however, in more severe cases of prolonged dampness, visible damp patches may appear, along with hygroscopic salts on the wall surfaces.
Effective treatment requires removal of the wall plaster to approximately one meter or higher (depending on the salts within the masonry and several other factors) along with the installation of a new damp proof course.
Damp Proofing Walls
How is a damp proof installed?
The method of installing the damp proof course is by pattern drilling the masonry at the base of the wall and injecting a specially formulated solution of Kenwood silicone injection fluid.
The injection process is low odor and cures within the masonry wall to form and the impervious barrier to rising dampness, which prevents moisture rising from the ground into the treated walls. Adjacent abutting walls are isolated using a vertical damp proof course.
Used in conjunction with our specialist waterproof rendering system this provides a reliable and cost-effective method of treatment.
The new damp proof course will prevent moisture rising and the masonry will begin to dry out, however, due to the effects of ground salts, the walls will not dry out fully unless the existing plaster is removed and replaced using a salt retardant render, such as Waterproof Rendering System.
