What is DPC damp proof course?
What is DPC damp proof course?
A damp proof course (DPC) is a physical barrier that prevents water from moving up a wall. This process of water travelling up through walls is known as rising damp. You can either use liquid DPCs or physical DPCs to prevent this from happening. Many homes will already have some form of DPC.
How high should DPC be above ground?
Ensure the dpc is a minimum 150mm above external ground level.
What is the thickness of DPC?
The DPC should be of 40mm thickness and should be of uniform thickness. It should not be provided at the locations of the door openings. The top level of DPC should match with the planned finished floor level.
Can DPC be higher than 150mm?
As long as the Dpc is a minimum of 150mm from the ground, you can step the dpc as much as you like. However, the dpc on the internal wall, should be level all the way round to match the existing dpc level.
What do you mean by DPC?
A damp proof course (DPC) is a form of damp proofing installed in a property to prevent rising damp and associated problems.
Why DPC is used?
The damp proof course prevents damp from the ground rising up the walls and damaging your property. Properties which have no appropriate damp protection layer or has a damaged damp course may be affected by excess moisture rising from the ground.
Do I need a damp proof course?
Why do you need a damp proof course A functioning damp course is an essential part of any property in order to prevent moisture from the earth and soil rising up the walls through capillary action (also known as rising damp) and damaging the property as a result.
Is a damp proof course necessary?
The reason why a damp proof course is important is because any excess moisture entering a building can lead to more serious property problems such as timber decay or structural damage. Properties that do not have an effective damp proof course are more prone to suffer from the following: Wet rot. Dry rot.
Should damp proof course be visible?
Unlike timber suspended floors where the damp proof course will be sited below floor level with solid constructed floors the DPC should always be sited above finished floor level and should be visible.
Where should a damp proof course be installed?
All damp proof courses must be laid between an even, fresh bed of mortar in continuous lengths for the full width of the wall or leaf and preferably project beyond the finished external face of the external leaf. (including any externally applied render).
What is damp-proof membrane?
A damp-proof membrane is a moisture-inhibiting foil that is 100% watertight (unlike a breather membrane!). Thus damp – which exists in the surrounding air in the form of condensation – is prevented from penetrating the membrane.
What materials are commonly used for a damp proof course?
Using grout or concrete to fill gaps and voids in a buildings formation is an inexpensive and practical option for a damp proof course. Usually determined by a professional, holes are drilled into specific areas of the building before concrete is pumped into the voids to make it damp proof.
