Damp Proofing Quotes in Havant Hampshire

Rising Damp Havant Hampshire

Dealing with rising damp issues can be as simple as checking your outside walls to see if you can spot a DPM. For satisfactory protection it ought to be 150mm (about 6") above the level of the ground. If you find this gap doesn't exist, you could dig away the ground to increase it, or if this approach is not possible, a higher DPM will need to be put in.

If this is not the problem and your damp course is in order, there could be more serious issues to resolve caused by the moisture rising up from the ground beneath, through your floor, and into the walls.

Havant damp proofing experts will quickly be able to identify the cause of your rising damp issues, and employing a number of different techniques will soon deal with the problem.

Another remedy for minimal areas of membrane damage may include painting with a bitumen based, waterproof latex emulsion. This has to be applied underneath your floor coverings, so tiles, carpeting and wooden flooring must be lifted prior to work being done. This is particularly effectual in basement areas as an integral part of the tanking process to create a room which is watertight. For further protection in these troublesome areas, your Havant damp proof specialist may recommend the use of building paper (a specialist foil backed membrane) before the bitumen coating has completely dried out.

Tanking: Tanking an area, such as a basement or part below ground space, is a process of covering any exposed surfaces with a waterproof paint. Since this waterproof coating must be applied to the bare surface of floors and walls, all plaster and wall covering must be taken off before any work can commence, and all surfaces prepared properly. Once this paint has been applied, it should be permitted to dry thoroughly before replastering and decorating over the top of it. This is a really disruptive job as it must be applied to a whole basement level or ground floor of a building, and it is recommended that you obtain more than one expert opinion on whether this is really the only answer to your rising damp problems.
