Damp-Proof Course

/Damp-Proof Course

Damp-proof course (DPC) forms a damp-proof membrane (DPM) to act as a barrier to rising damp. Construction regulations require damp-proof course as standard to prevent rising damp and penetrating damp in new buildings.

Technical Info

Above Adjoining Ground Level: 150mm.

Clear Wall Cavity Depth: 225mm.

DPC with DPM: continuous.

Benefits

Prevents surface condensation, interstitial condensation and rising damp.

Prevents frost damage.

Improves the performance of insulation.

Prevents corrosion / decay of the building fabric or damage to surface finishes.

Prevents mould growth due to damp.

Process

Materials can absorb moisture and damage wall structures, joints that support doors / window frames / timber beams; so a damp-proof membrane can prevent the moisture from corroding the installation.

NEW BUILDS
Damp-proof course can be made with bituminous material, polyethylene, engineering bricks / slates or any other material that resists moisture.

OLD BUILDS
Leaks or defects may develop in the structure with time, these must be identified and corrected before any damp-proof course. Buildings without DPC require a moisture-impermeable layer created by damp-proof course, or injecting water-repellent chemicals.
