Yes, you can use dry rods on internal walls to treat rising damp. However, the correct rod length is crucial for effective application.
Here's a breakdown of how to use dry rods on internal walls:
-
Wall Thickness Matters: The length of the dry rod you use depends on the thickness of your internal wall.
-
Cutting the Rods:
- For walls thinner than 9 inches (220mm), the dry rod should be cut 10mm shorter than the length of the drilled hole.
- For walls thicker than 9 inches (220mm), insert one rod. Then, measure the remaining space in the hole and cut a second rod 10mm shorter than this measurement.
-
Pre-Cut Options: Dryrod is available in pre-cut 85mm lengths, specifically designed for 4 ½ inch internal walls.
In summary, dry rods are suitable for internal walls, provided you select or cut them to the appropriate length according to the wall thickness.
