2024年5月31日 · One of the most effective and historically sympathetic solutions for addressing damp problems in traditional homes is the installation of slate damp proof courses (DPCs). These specialised courses, made from high-quality slate, act as a barrier to prevent rising damp from penetrating the building’s walls.

2011年1月2日 · Beds of natural slate were quarried and the heavily compressed, dense material that was formed in layers was split to thin slates that were sufficiently impermeable to water to serve as an effective dpc. Two courses of dense Welsh slates were laid at first in lime or hydraulic Iimc and sand, and later in cement and sand.

2023年1月22日 · SLATE BED DPC. A slate DPC is a type of moisture barrier that is made of slate and is used to prevent the passage of water through walls and foundations. The slate DPC is typically installed in the mortar joint between the brickwork or stonework of a building, creating a barrier that prevents water from penetrating into the walls and floors.

2023年1月24日 · To get a better understanding of the damp proof course in old houses it’s important to know how a DPC works and understand the construction style of your home. This guide will provide a full overview of an old house’s damp proof course, what it does and importantly what not to do to an old house.

2018年10月12日 · A DPC is a solid layer built into the wall and is placed above ground level so as to prevent the moisture from rising over the wall through capillary action. The material used in those times for DPC included – bitumen, jute, slate, and hessian. A layer of slate was the most common form of DPC then.

2023年2月1日 · A damp proof course (or DPC) is a layer built into a wall, or injected at a later date, which prevents moisture rising up the wall via capillary action. Without a damp-proof course, rising damp will move from the ground and up the wall; in most cases, this will be to a height of around 500 – 600mm above floor level.

2021年4月13日 · In the later part of the 19th Century properties started to be built with an installed damp proof course (dpc). These were slate dpc’s and years later many properties had a Bitumen dpc installed. The main purpose of a Damp Proof Course is to prevent moisture rising room the ground into the wall .

A Damp Proof Course (DPC) is an impervious layer built into a wall. It is placed above ground level to prevent moisture rising up the wall via a capillary action. Older buildings used a range of materials for a DPC, including slate, bitumen, jute and hessian.

2021年9月1日 · A DPC is a layer of damp proofing material laid between bricks to help prevent moisture rising through porous elements of a buildings via capillary action. By The Public Health Act 1875 it is now a requirement of the Building Regulations (Approved Document C) that walls should resist the passage of moisture.
