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 of the surfaces. Range of treatments.

Effective treatment requires removal of the wall plaster to approximately one metre or higher (depending on the salts within the masonry and several other factors) along with the installation of a new damp proof course.

The height of the necessary replastering will be individually specified on your quotation, once our surveyor has carried out an inspection of your property. Replastering above one metre high is not uncommon.Penetrating dampness can cause structural difficulties

Damp Proofing Walls

How is a damp proof course 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 siliconate injection fluid or Kenwood DPC cream, until the entire depth is fully impregnated.

Dealing with condensation and damp

Kenwood Plc’s chemical injection process, is low odour and cures within the masonry wall to form and 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, effective and cost effective method of treatment. See repairing damp.

How to cure damp

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 Kenwood’s Premix Waterproof Rendering System.

The benefits of the Kenwood’s Waterproof Rendering System can be found under the ‘Specialist Replastering’ section of our website. Following the application of the waterproof rendering system, we apply a top coat skim plaster to provide a smooth plaster finish.

Stop rising damp

Where high ground levels are present, Kenwood SWS Tanking system may also be required in conjunction with the chemical damp proofing and resolving damp walls.
