Damp Proof Course in Ireland’s Construction IndustryJosephSapsed
Damp Proof Course, commonly known as DPC, is an essential component in the construction industry. It is a horizontal barrier placed within the walls or floors of a building to prevent moisture from entering the structure. In this blog post, we will discuss the key benefits of DPC in the Irish construction industry, and when and how it is used.
What is DPC?
Damp Proof Course is a physical barrier, typically made of materials such as slate, bitumen, or plastic, which is installed horizontally within a wall or floor. It is usually placed at the base of the wall or floor, where it can prevent moisture from entering the structure.
Key Benefits of DPC in the Irish Construction Industry
- Prevents Dampness and Moisture Damage
The primary benefit of DPC is that it prevents dampness and moisture from entering the building structure. Dampness can cause serious damage to a building, such as structural decay, wood rot, and mold growth. By preventing moisture from entering, DPC ensures that the building remains dry and structurally sound.
- Increases Energy Efficiency
Dampness can also lead to increased energy consumption as it can affect the thermal insulation of a building. By preventing moisture from entering, DPC helps to maintain the insulation’s effectiveness and, therefore, reduces energy consumption, ultimately making the building more energy-efficient.
- Provides Long-Term Protection
DPC is a long-term solution to prevent moisture ingress. Once installed, it can last for decades, providing continuous protection against dampness and moisture damage.
When is DPC Used?
DPC is used in both new construction and renovation projects. It is typically installed at the base of the walls, between the foundation and the first course of masonry, or between the concrete slab and the first course of blockwork.
In addition to walls, DPC is also used in floors to prevent moisture from entering through the ground. It is installed between the concrete slab and the insulation layer or between the insulation layer and the floor screed.
How is DPC Installed?
DPC is installed during the construction process, typically as part of the wall-building process. The material used for DPC is cut to size and inserted into a groove in the wall or floor. Once installed, the DPC material is sealed to the wall or floor, ensuring that there are no gaps or spaces for moisture to enter.

By preventing dampness and moisture damage, DPC ensures that the building remains structurally sound and energy-efficient. In addition to new construction, DPC can also be installed in renovation projects to protect against dampness and moisture damage.
