What Is Damp Proofing, And What Are The Benefits?

Damp proofing is the process of making your home resistant to dampness and moisture. There are several ways to handle this, but the most common method is installing a damp proof course (DPC), a physical barrier preventing water from rising through the walls or floors.

There are many benefits to damp proofing your home, including:

Preventing damage to your property: Damp can cause severe damage to both the structure of your home and your possessions. By damp proofing your property, you can protect it from this type of damage.

What Are The Different Types Of Damp Proofing Methods Available To
Homeowners Today?

There are several methods available to homeowners looking to damp-proof their homes.

Chemical Damp-Proof Course: A course of chemicals is inserted into the mortar bedding of walls to prevent water from rising through them.

Mortar Damp-Proof Course: A physical barrier, usually 50-100mm thick, inserted into the masonry of a building at or near ground level to prevent the passage of moisture. The most common type is a bitumen-based felt course.

Damp-proof membranes (DPMs): A horizontal layer of material, usually polythene, is placed in the foundation trenches beneath the floor slab before concrete is poured. Its purpose is to provide a waterproof barrier to prevent water from rising through the slab from underneath the wet ground.

Cavity trays: These are used where two walls meet at an external corner or where a wall abuts a parapet (a low wall at the edge of a roof). They form a ‘pocket’ behind the wall to collect any water that might penetrate the outer leaf and direct it back out through the cavity to a suitable drainage point.

Weep holes: Small openings (usually around 12mm diameter) drilled in the brickwork at intervals of about 600mm. They allow any moisture that has penetrated the wall to drain out. This prevents it from being trapped inside, where it could cause dampness.


Waterproofing is an essential part of home maintenance, and it’s something that should be done regularly.
