Rudders & Paynes has a history dating back to 1956, arguably - it's the best known and most highly regarded name in the Remedial Treatment Industry in the West Midlands.

Rising damp solutions

One of the most common problems affecting buildings in the U.K. is Rising Dampness, yet it is frequently misdiagnosed or inappropriately treated resulting in re-occurring problems and costly repairs.

Rising dampness is the passage of moisture from the ground through the capillary fissures or pores in masonry thereby raising the moisture content in the lower part of the wall to unacceptable limits.  Symptoms can include spoiled decorations, damaged plaster and decay to adjoining timber floors and skirting.  Externally brickwork may become damaged and salt crystals can emerge externally and/or internally.

We have been one of the foremost authorities on the eradication of rising dampness in residential, commercial, historical and ecclesiastical buildings for over 50 years and have successfully treated thousands of buildings across the Midlands.
In the first instance, our investigation will centre upon causes other than rising dampness.  Often the cause of problems will become obvious to the trained eyes of our experienced, qualified surveyors.  Only when other causes have been discounted and our investigation has complied with British Standard 6576 and rising dampness proven, will we suggest the installation of a BBA approved silicone damp course; which will be formally guaranteed to solve the problem for a period of not less than 20 years.

In cases of true rising dampness wall plaster is always affected by salts that migrate with the dampness from the ground and from building materials.  The salts will invariably cause the breakdown of wall plaster or cause the plaster to absorb moisture from the air and fail to dry out satisfactorily.  Therefore, as part of our recommendations, wall plaster at the lower part of affected walls should be replaced with a specification for re-plastering designed to prevent these problems.  Normally, our quotation will include for both the installation of a silicone damp course and removal of old plaster and re-plastering.

Not all walls that are affected by rising dampness should be treated with standard damp proofing systems. Stone walls, very thick walls, rubble filled walls and some listed buildings may be better treated utilizing moisture ‘sinks’ and surface evaporation (breathing).  In these instances internal membranes with air gap technology may be recommended in conjunction with lime plaster or insulated dry lining systems.  Rudders & Paynes have successfully treated many listed buildings and even ancient monuments using these tried and tested systems.
