Don't let moisture become your building's worst enemy. The Fortune DPC 100MM 4" Damp Proof Course (supplied in a convenient 9roll pack) is the professionalgrade solution trusted by builders and contractors to keep structures safe, dry, and built to last — from the very first course laid.

Every construction project faces the same invisible threat: rising damp. Left unchecked, moisture silently destroys foundations, warps timber, corrodes steel, and creates the damp, unhealthy interiors that homeowners and occupants dread. This rollout DPC membrane is your first and most reliable line of defence — installed once, protecting for a lifetime.

• Stops moisture before it starts — Creates a robust, continuous barrier within your wall structure, preventing ground moisture from ever reaching the living or working spaces above.
• Protects the health of occupants — A dry building is a healthy building. By blocking the conditions that allow mould, mildew, and bacteria to thrive, you're helping to ensure cleaner air and a safer environment for everyone inside.
• Keeps energy bills down — Wet insulation is wasted insulation. By keeping wall cavities dry, DPC helps your insulation perform at its best — meaning better heat retention in winter and cooler interiors in summer.
• Preserves your investment longterm — Concrete, brick, timber, and steel all suffer under persistent damp. Laying a quality DPC membrane extends the serviceable life of your entire structure, protecting the value of the build for decades.
• Saves money on costly remedial work — Reactive damp repairs are expensive, disruptive, and avoidable. One pack of Fortune DPC rolls laid correctly at construction stage eliminates the risk of bills that can run into thousands further down the line.
• Easy to handle and install — Supplied as 9 rolls per pack for straightforward site management, the 100mm (4") width is ideal for standard cavity and solid wall construction, making it quick to roll out and trim to length.

Whether you're laying foundations for a new home, extending an existing property, or working on a commercial build, Fortune DPC 100MM gives you the confidence that moisture will never compromise your work. It's a small step in the build process that makes an enormous difference to the finished result — and to everyone who lives or works inside.

Build it right. Build it dry. Build it with Fortune.
