Rising Damp

B.Barker Damp Control & Timber Preservation

Rising Damp

Rising Damp is caused by moisture rising from the ground into the walls of a building. Damp is able to rise up the walls because most construction materials contain tiny pores. These pores ‘suck’ water from the ground, causing moisture to rise up the wall.

The damp p

roof course may be missing altogether or may have failed or have been bridged or bypassed in some way. The damp does not rise quickly and does not normally reach higher than 1 metre up the wall. It leaves characteristic tide marks and sometimes salt deposits on this edge. The marks will look the same for long periods and are not normally affected by changes in climatic conditions.
This damp is usually seen on external and party walls above the skirting boards. If left untreated, further damage to the inside of the property will occur, including the rotting of floor joists and other internal timber with which it comes into contact.

Research has found that dampness - long associated with wheezing and coughing - is also a risk factor for asthma, partly because it helps the growth of the house dust mites which irritate asthmatics' airways. The findings report that children are more likely to stay asthmatic if they live in a damp home.

We provide the following damp proofing treatment to remedy the problem:

• The professional installation of a chemical damp proof course, using Triton Triject 3, a water-based damp proofing liquid intended for injection into walls affected by rising dampness. Triject 3 can be injected into pre-drilled holes formed either in the bricks or the mortar joints to form a continuous barrier against water rising from the ground. Within the walls, Triject 3 reacts with carbon dioxide to form a permanent water repellent coating within the capillaries of the masonry. The active ingredient is Potassium Methyl Siliconate.
