Dry Rod - Protection from Rising Damp

What Are Dry Rods?

Dry Rods are specialist damp-proofing rods used to stop rising damp. Inserted into the mortar line, they form a chemical barrier that blocks moisture from travelling upward through brickwork and masonry.

How Do Dry Rods Work?

Dry Rods create a chemical barrier in the masonry, preventing moisture from rising through walls. They release a solution that reacts with brickwork, forming a permanent, waterproof barrier to stop capillary action.

Does Dry Rod Protect From Rising Damp?

Yes. Rising damp happens when groundwater moves up the walls via capillary action. Dry Rods stop this by creating a long-term barrier in the masonry. Certified by the BBA (Certificate No. 97/3633), they are proven to remain effective for at least 20 years.

How Long Do Dry Rods Take to Work?

Dry Rods begin working straight after installation. Visible results may vary depending upon wall thickness and damp levels, but most walls dry out within 6–12 months. For persistent humidity, consider pairing with our Positive Input Ventilation (PIV) systems.

Difference Between Wet Rods & Dry Rods?

Wet rods and dry rods both serve the purpose of preventing rising damp, but they differ in their application and effectiveness:

  • Dry Rods:
    These are solid, chemically impregnated rods that are inserted into the mortar joints. They slowly release chemicals that block moisture. Once installed, Dry Rods remain effective for 20 years or more.

  • Wet Rods:
    Unlike Dry Rods, they are liquid-based solutions that are injected into the wall, creating a temporary barrier that eventually evaporates or degrades. Wet rods may not offer long-term protection like dry rods and often require reapplication.

Signs Your Home Needs Dry Rods

Typical symptoms of rising damp include:

  • Peeling wallpaper or flaking paint near the floor

  • A tide mark or damp patches at the base of the walls

  • Crumbling plaster or salt deposits

  • Musty smells and cold walls
