If you live in England, it’s critical that your home has a damp-proofed structure to protect it from problems like penetrating damp, rising damp, and beneath-ground damp. A Damp Proofing system is a moisture control barrier that may be utilized to block moisture from entering the interior living areas of buildings. Damp problems in construction are very prevalent throughout the UK, and damp remediation treatment is one of the most often performed property maintenance repairs.
Although it is difficult to repair, timber rafters are not as vulnerable to water penetration as concrete and masonry walls. A horizontal and vertical damp-proof barrier is required at the proper location for concrete and masonry walls, however, this isn’t necessary for wood rafters. DBI LTD can install a damp proofing system that matches your property:
A damp-proof course (DPC) is a barrier that can be put in place of a building’s above-ground level to prevent capillary action from causing damp to rise. If capillary action isn’t stopped, rising damp could develop. A DPC layer is routinely installed in all masonry walls, regardless of whether they are load-bearing or partition walls, to protect them from rising damp.
A damp-proof membrane (DPM) is a permeable sheet that is used to prevent moisture from entering the property. This is most commonly installed below a concrete slab.
Adding water proofers to the concrete mix makes it moisture resistant.
Waterproofing and finishing are the applications of waterproof materials used to resist non-pressurized moisture, such as rainwater.
What method do you employ to install a damp-proofing course (DPC)?
There are a number of ways to get a solid, preventative damp proofing system in place:
A chemically injected DPC is most often inserted with a specially prepared cream or water-based solution. The correct height of the wall is determined by a member of our Richardson and Starling staff, and the chemical is then injected into the holes, creating a barrier against rising damp.
In random rubble stone walls, especially in masonry construction, the DPC technique is commonly employed. Our specialists will drill holes in the wall and apply a specially formulated cement-based mortar.
A DPC may also be achieved by utilizing an electro-osmosis system. This technology utilizes an electric charge that is applied to the wall via wires and grounded to the ground to reverse capillary action and pull damp back into the earth.
Why must damp proofing course works involve the removal of the plaster?
During the damp proofing procedure, the plaster must be removed since rising damp from the earth not only contains moisture, but also contains hygroscopic salts, nitrates, and chlorides.
Hygroscopic salts attract moisture from the air. These salts will seep into the plaster within the building, and even after a successful DPC intervention, salty plaster can still become wet. It is critical that polluted plaster be removed and replaced during therapy.
Our specialists will take out only what is absolutely necessary and in most situations, this will be one meter above the floor level. Damp may rise to a height of up to one meter above ground level depending on the site’s construction and conditions. Each instance of damp is unique, therefore the repair will be determined based on the property.
