Treatments for Rising Damp in Barnsley

Rising damp in Barnsley is the process of water rising vertically up from the ground and travelling by capillary action through porous material such as bricks and mortar. This will cause the wall to become damp as hygroscopic salts travel into the brickwork and plaster. As water evaporates, these salts are deposited into the wall attracting more moisture from the atmosphere.

As the process continues the wall and surrounding area becomes more saturated and signs of rising damp will become evident such as crumbling of plaster and white tide marks appearing on a wall up to a height of around 1 metre. Problems such as dry rot, wet rot and wood boring beetle infestations are also more likely to occur as surrounding timbers become saturated. It is a slow process and can be present for many years before any sign of a problem appears.

Rising damp in Barnsley will typically occur due to:

  • No damp proof course (DPC) as is commonly the case with older buildings
  • Deterioration and failure of the DPC over time
  • Changes in external ground levels meaning the DPC becomes bridged. For example if a new patio has been laid
  • Moisture traveling in between the wall and the render so bypassing the DPC.

Treatment of Rising Damp

There are a range of solutions involved in the treatment of rising damp Barnsley which have to work in combination with each other and be carried out correctly using the correct specifications and materials to ensure treatment is successful. Curedamp Ltd  will conduct a diagnostic survey before recommending the best course of action. Our surveyors have the experience to ensure the best solution is recommended and applied.

Solutions can be considered in terms of above and below ground solutions as follows:

Above ground

A chemical injected damp proof course will involve drilling into each brick at carefully calculated intervals then injecting under pressure the silicon 8 fluid or gel. This forces the chemical into the brick which creates resistance to moisture. The height of where you inject is determined by the site conditions such as external ground levels and internal subfloor levels.

The treatment usually takes place from the inside as external renders and plinths can make it difficult to do from the exterior of a property. As part of a damp proofing system, contaminated plaster will be hacked off and replaced using a specialist replastering specification (adhering to BS6576/1985 guidelines).

Other solutions may also be specified to work in combination. This may include an application of the Stormdry water repellent masonry protection cream to give additional protection in particular situations such as when bricks are highly porous, if a wall is heavily exposed to wind drive rain or if ground levels means rain water splashes up and over the damp proof course.

Below ground

If the wall is a party wall and/or there is a possibility of lateral penetrating damp such as where there is an internal suspended timber floor or solid floor combined with high ground bridging the damp proof course, it is recommended to apply a waterproof cementitious membrane. This will be required below the injected damp proof course to protect the skirting and sub floor timbers. A cementitious membrane uses a cement based chemical slurry which when plastered onto the wall reacts and penetrates the prepared surface to prevent water moving through earth retaining walls.

This method can work in conjunction with a chemical DPC system and also as a solution for basement waterproofing either in combination with a cavity drainage waterproofing system or as a standalone solution.
