Solution — "Damp keeps rising up my walls no matter what I do"

Chemical DPC Injection

Rising damp is a problem that is often misdiagnosed, and it is a problem that is often treated with the wrong solution. The damp is rising from the ground, and it is rising because the damp-proof course at the base of the wall is missing, or it is broken, or it is bridged. The water is being drawn up the wall by the capillary action of the bricks and the mortar, and it is carrying the salts from the ground with it. The first step is to confirm that the damp is rising. The pattern of the damp is the key — rising damp is a damp that is at the base of the wall, and it is a damp that is rising to a height of about a metre. The damp is also a damp that is carrying the salts, and the salts are visible as a white deposit on the wall. We measure the moisture content of the wall at different heights, and we confirm the diagnosis. The treatment is a chemical damp-proof course. The chemical is injected into the wall at the base, and it forms a barrier that stops the water from rising. The chemical is a silicone that is injected into the wall, and it is a water-repellent that blocks the pores of the wall. The chemical is injected into the wall at a series of holes, and the holes are spaced along the wall. The chemical is injected into the wall at the base, and the injection is carried out at a level that is above the floor. The chemical is injected into the wall, and the chemical is absorbed by the wall. The chemical is a water-repellent that blocks the pores, and the water is stopped at the level of the injection. The plaster is also a part of the system. The plaster that is affected by the damp is removed, and the wall is re-plastered with a salt-resistant plaster. The salt-resistant plaster is a plaster that is designed to the salts, and it is a plaster that is not affected by the damp. The plaster is applied to the wall, and the wall is finished. We also look at the cause of the rising damp. The damp is often caused by a broken damp-proof course, but it is also caused by a bridged damp-proof course. The damp-proof course is bridged when the ground is built up against the wall, or when the render is carried down over the damp-proof course. We address the cause, and we make sure the damp-proof course is not bridged. The result is a wall that is dry, a wall that is free of the salts, and a wall that is protected. We document the system, we provide the specification, and we stand behind the work. The first thing we do is look at the wall. The wall is the structure that is the damp, and the wall is the structure that is the water. We look at the wall, the base, and the height, and we find the cause of the problem. The base of the wall is the first thing we check. The base is the point that is the wall, and the base is the point that is the water. We check the base, the damp-proof course, and the ground, and we find the path of the water. The height of the damp is the next thing we check. The height is the height that is the damp, and the height is the height that is the water. We check the height, the salts, and the plaster, and we find the path of the water. The result is a wall that is dry, a wall that is protected, and a wall that is the water. We find the path of the water, and we stop the water. The first thing we do is look at the wall.

Our approach

  • On-site inspection to confirm the source and extent of water ingress
  • Substrate testing where relevant (moisture content, adhesion, cracking)
  • Written specification naming the system, prep required, and application method
  • Certified application following manufacturer specification
  • Documented sign-off and warranty information on completion

Not sure this is your problem?

Symptoms often overlap — a damp wall can trace back to a roof detail, not the wall itself. A site visit gives a definitive answer at no obligation.
