Function ~ the primary function of any damp-proof course (dpc) or damp-proof membrane (dpm) is to provide an impermeable barrier to the passage of moisture. The three basic ways in which damp-proof courses are used is to:-. Building Regulations, Approved Document C2, Section 5: A wall may be built with a damp-proof course of bituminous.
FFL at ground level Damp & DPCs
A Damp Proof Course (DPC) is a continuous barrier installed in buildings to prevent capillary climb of water in walls. Current building regulations state that walls must resist the passage of water from the ground and that this requirement can be reached if a damp proof course is provided. Therefore almost all modern houses within the UK will.
Damp Proof Course (DPC) Methods of DPC application in Construction Cement Concrete
DPCs are now required to construct new buildings, preventing rising/penetrating damp which can lead to costly repairs due to mould and damp in the building materials.

In all cases, cover flashings should be built-in under the stepped DPC. Metal used for flashings should be non-ferrous. In cases where lead is used, the lead should be at least a code four (colour code blue). Laps for flashings should be greater than 100 mm (150 mm in locations prone to high wind and rain) and individual lengths should be less.

User note: About this chapter: Chapter 3 contains a wide array of building planning requirements that are critical to designing a safe and usable building. This includes, but is not limited to, requirements related to: general structural design, fire-resistant construction, light, ventilation, sanitation, plumbing fixture clearances, minimum room area and ceiling height, safety glazing, means.

The thickness of DPC is not a mere detail; it is a crucial factor influencing its effectiveness. Compliance with building regulations and considerations of environmental conditions guide this decision.. (DPC) in a building is a crucial construction element designed to prevent the capillary rise of moisture through walls, providing a barrier.

14.10.2021 News Cavity trays are an important feature in external cavity walls to assist in ensuring any water is directed outside the building. Incorrect specification or installation can lead to defects in the wall and water damage that might be expensive or needlessly destructive to rectify.

DPC barriers are required when constructing new buildings to prevent rising damp, and in some cases, it can also help prevent penetrating damp or water ingress. There are different regulations for walls and floors, as these face different risks and causes of damp - rising damp as well as penetrating damp and condensation must be protected against.
Building Guidelines Cavity walls DPC's
A damp-proof course is a barrier, usually formed by a membrane, built into the walls of a property, typically 150 mm above ground level, to prevent damp rising through the walls. Historically, damp-proof courses may have been formed using bitumen, slates, lead, pitch, asphalt or low absorption bricks. They emerged during the Victorian era and.

impermeable. Figure 9: DPC at least 150mm above finished ground level Figure 10: Stepped DPC levels on sloping sites Where homes are 'stepped' on a sloping site, care should be taken to link DPCs and DPMs so that all parts of each home are protected. DPC materials # Acceptable materials for DPCs include:
Building Guidelines Cavity walls DPC's
What is DPC? The damp proof course (DPC) is generally applied at basement levels, which restricts the movement of moisture through walls and floors. The selection of materials for the damp proof course and its various methods of applications in buildings is discussed. Materials for Damp Proof Course (DPC) Properties of Materials for DPC

Numerous lintels also act as a DPC but where these are less than 150mm in height (commonly many are 140mm) they do not technically satisfy the damp protection requirements demanded in Building Regulations Part C and British Standards unless accompanied with additional DPC protection providing the minimum dimension stipulated.

Damp Proof Course (DPC) Methods of DPC application in Construction Cement Concrete
A cavity wall is designed to prevent moisture penetrating to the inside face of the wall and causing damp problems in the building. In many situations it is necessary to include cavity trays in the wall, to prevent water penetration to the inner leaf.
