Rising Damp & How To Treat It

What is Rising Damp?

Rising damp is a form of dampness that is present in walls as a result of the water underground or next to walls rising through the fabric of the wall. It is a particular problem in older buildings where the damp proof course (DPC) has become damaged or when the ground level around the house has been raised by the addition of a path or driveway.

The Causes of Rising Damp

Causes of Rising Damp

Rising damp can occur as a result of ground water finding its way into your home through brickwork or stonework. This ground water contains soluble salts, which deposit on the interior and exterior walls of the property. In turn, these salts draw moisture from the atmosphere giving a permanently damp feeling to the wall. Most ground water contains small quantities of salts which are, in most cases, at an acceptable level. The dampness isn’t necessarily caused by rising damp as there maybe another source of water that you are unaware of causing the problem.

It is important to understand that penetrating damp is the most common form of dampness compared to rising damp. To find out more about the pentetrating damp then click on the following page below:

What are the Signs of Rising Damp?

Identifying Rising Damp in the property

There are certain checks that can be made by yourself without the assistance of a damp surveyor. The simple procedure of looking and running your hands around the suspected rising damp areas will allow you to identify a rising damp problem. The typical signs of identifying rising damp include the following:

  1. Horizontal brown or discloured marks to be seen up to 1 meter in height on interior walls. These will be damp to touch and otherwise known as ‘Tide Marks’
  2. Plaster will bubble and peel away from the interior walls
  3. Wooden beading and skirting boards will become brittle and eventually show the signs of deterioration
  4. Mould on walls
  5. Walls will feel damp when touched

If any of these signs of damp are suspected within the property then contact Timberwise where our expert team of surveyors can provide you with the right treatments to eradicate any damp problems you may have. Call 0800 288 8660 or request a property survey by clicking the link below.

Treating Rising Damp

Any form of rising damp must be stopped at the source to be sure that the damp problem is fully rectified. Carrying our quick fixes will only cover up the issue for a short term period and therefore make it more expensive for you to solve in the long term.

To solve the issue of rising damp in your property you may require the installation of a damp proof course. For a professional rising damp treatment service, Timberwise will provide an experienced surveyor who will visit your property and outline potential damp proofing treatments and costs. Our damp proofing specialists will control rising damp through 3 methods:

Rising Damp Treatment Methods

Rising damp treatment being appliedDri-Wise Pressure Injection

Dri-Wise damp proofing cream is a unique product to Timberwise, this water based product is injected into old brick and stonework structures and into granite boulder walls. This creates a barrier that moisture cannot pass, the cream will tend to fill any fine cracks and this forms a solid plug. This product comes complete with a 20 year guarantee giving complete peace of mind.

Injection Mortar

This grouting type of material is ideal for many applications, particularly where a good sized bedjoint is in evidence. The damp proofing agent is carried into the porous mortar beds and rubble by the rising damp, where it crystallises to form an impermeable barrier to control subsequent water rise.

Timberwise EOS (Electro Osmosis System)

The Electro Osmosis System introduces a very small electric current into the wall just above the ground level. The current repels rising moisture back down the wall. As long as the charge is maintained the walls will remain dry and free of damp.

Preventing Rising Damp Issues

Most of the modern buildings in the UK have a damp proof course which can act as a barrier water penetration. However, there are some cases where there is damage that affects the building and damp can become a problem. All the external masonry, guttering and rainwater pipes should be properly maintained.

There should be regular checks for signs of dampness on internal surfaces on the ground floor surfaces and skirting boards. Checks should also be made on ensuring that external roofs, gutters and roof pipes should be free from debris as much as possible. All air vents must be free from obstruction to allow air to flow freely out of the building.
