Damp Proof Course (DPC) for Walls

Description

Horizontal Capillary Rise Barrier for Brick & Masonry Walls

Our Damp Proof Course (DPC) provides an impenetrable horizontal barrier that isolates vertical wall structures from ground-water creep. Bricks and mortar beds naturally behave like a dense sponge, drinking moisture from the foundation footer and carrying it up into the building shell (rising damp). This specialized DPC line halts that capillary rise permanently, ensuring your internal breathing zones remain completely free from bubbling paint, damp plaster rot, and structural decay.

Best Used For:

• Inserting horizontally during new-build bricklaying, blockwork, and stone construction
• Retrofitting and structural damp remediation in older, historic masonry walls
• Sealing door and window frame lintel openings to prevent moisture tracking paths
• Creating water-tight barrier junctions where walls meet floor slabs and footers

Key Benefits & Features:

• Continuous Capillary Block: Forms a dense, non-porous physical layer that shuts down the upward migration of groundwater, stopping the structural dampness that triggers musty odors and toxic mold growth.
• High Mortar Grip: Features an embossed grid pattern on both sides of the polymer strip. This texture maximizes the mechanical lock between the cement mortar and the DPC sheet, keeping walls structurally stable.
• Heavy Weight Tolerance: Engineered to withstand intense, continuous compressive weight loading under heavy brick and stone walls without rupturing, splitting, or extruding.
• Long-Term Weathering Defiance: Chemically inert material remains fully uncompromised over decades of service, resisting degradation from high-alkali cement mixes, ground salts, and acids.

Technical Specifications & Handling:

• Product Material: High-Density, Embossed Polyethylene (HDPE Hybrid)
• Product Profiling: Available in pre-slit roll widths to match standard brick and block wall sizes
• Installation Protocol: Must be laid flat onto a fresh bed of mortar, with sections lapped by at least 100mm and sealed with DPC joint adhesive at junctions. Ensure it links continuously with your sub-floor Damp Proof Membrane (DPM) for total structural encapsulation.
