Damp Proofing

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 or renovation.

There are many ways in which rising damp may be found in a property. Rising damp may be found during a Building Survey, by tests carried out to the base of the damp walls, however in more severe cases where damp has been left untreated for prolonged periods of time, visible damp patches may appear, along with hygroscopic salts on the surface of the walls.

Effective damp proofing treatment requires removal of the wall plaster to approximately one metre or higher (depending on the salts within the masonry and several other factors). In addition to this, installation of a new damp proof course within the damp walls will help to provide protection for the property.

Damp Proofing Walls

How is a damp proof course installed?

The method of damp proofing walls involves two key elements. Installing a damp proof course is by pattern drilling the masonry at the base of the damp walls and injecting a specially formulated solution of Kenwood siliconate injection fluid or Kenwood DPC cream, until the entire depth is fully impregnated.

Kenwood PLC’s injection process when damp proofing walls, is low odour and cures within the masonry wall to form an 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 as part of the damp proofing treatment.

Used in conjunction with our specialist waterproof rendering system this provides a reliable and cost-effective method of treatment to ensure damp walls are no longer an issue in your home.

The new damp proof course within the damp walls will prevent moisture rising and the masonry will begin to dry out. However, due to the effects of ground salts, the damp 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.

Kenwood’s Waterproof Rendering SystemThe benefits of the Kenwood’s Waterproof Rendering System ensure perfectly batched renders where the proportions of sand, cement, lime and waterproofers are computer controlled in factory conditions, and not determined by site operatives ‘mixing’ the products together from various bags of material.   Following the application of the waterproof rendering system, when damp proofing walls, we apply a top coat skim plaster to provide a smooth plaster finish.

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