Injecting a wall against rising damp

Injecting a wall against rising damp

When you are dealing with damp building up from the bottom of your walls, there is a good chance that this is due to rising damp. This problem occurs when the water barrier of your house or building is missing or damaged and groundwater is, effectively, sucked up through the walls. Especially in older houses you will regularly see this happen. It is important to deal with moisture problems quickly to prevent damage to the building and your health.

With WP7-402 Stop Rising Damp you can effortlessly inject your walls and bid farewell to rising damp.

Step 1: Preparation

  • Determine the correct drilling depth by measuring the wall thickness or by penetrating the wall.

  • Reduce the measured value by 5 cm.

  • Mark the drilling depth with a piece of tape on the drill.

  • The drilling diameter should be 12 mm.


Step 2: Drilling

  • Drill a 12 mm hole every 10 cm. Respect the depth as marked on the drill.

  • For maximum efficiency, drill in the lowest horizontal joint above the ground surface.

  • If you have a porous stone, such as sandstone, it is best to inject the stone itself as well.

  • If you have an old water barrier, you should drill into the joint just below the water barrier.

  • Remove all the drilling dust.


Step 3: Injecting

  • Screw the WP7-402 Stop Rising Damp injection hose onto the nozzle of the product packaging.

  • Insert the injection hose into the back of the drilled hole and fill it with a slowly retracting motion.

  • Leave the last cm unfilled.


Step 4: Finishing
