At Unitech SA, we’ve seen first-hand how moisture problems can compromise the comfort, value, and structure of a home. That’s why we always emphasise the importance of installing a proper damp proof course (DPC) — especially during new home construction.
What is a Damp Proof Course?
A damp proof course is a protective layer built into the walls of a home, typically near the base. Its main purpose is to stop moisture from the ground rising up into the structure — a common issue in homes that leads to damp patches, peeling paint, and even mould.
The DPC acts as a barrier, keeping unwanted moisture out and ensuring that your walls remain dry, stable, and protected over time.
What We Do to Get It Right
At Unitech SA, we consider drainage at the start of every foundation design. It’s not an afterthought—it’s part of the plan. Here’s how we build for long-term performance:
-
Site Sloping: We evaluate the natural slope of the site to ensure water drains away from the house, not toward it.
-
Drainage Channels: We install swales, trenches, and other systems that redirect rainwater and groundwater.
-
Subsurface Drainage: For certain builds, we install French drains or perforated pipes to carry water away from beneath the foundation.
-
Gutter & Downpipe Coordination: We make sure water from the roof doesn’t pool at the base of your home—because what’s the point of good roofing if it ruins your foundation?
-
Waterproofing Measures: In certain soil types or wet areas, we add waterproofing layers and sealing systems around the foundation.
Why It Matters
There’s more to DPC than meets the eye. Here’s why it plays such a vital role:
-
Prevents Dampness
A DPC blocks rising damp before it starts, helping to prevent water damage and surface deterioration. -
Protects the Building’s Structure
Moisture weakens bricks and mortar over time. A quality DPC helps maintain the long-term integrity of the structure. -
Improves Indoor Air Quality
Damp environments encourage mould growth and poor air quality. DPC helps create a healthier, drier living space. -
Reduces Future Maintenance
With a properly installed DPC, you reduce the risk of moisture-related issues — and the costly repairs that follow.
The Long-Term Benefits of Damp Proof Course
For homeowners, a damp proof course offers real, lasting value:
-
Durability
It supports the longevity of your home by keeping moisture damage at bay. -
Healthier Living Conditions
By minimising damp, your home becomes a cleaner, safer space for your family. -
Increased Property Value
A DPC reflects quality construction and attention to detail — two things buyers are always looking for.
