Resin injections to block rising damp are a common and effective method of treating rising damp problems in buildings such as foundation walls and perimeter walls. This problem occurs when ground water is absorbed by building materials, causing structural damage and health problems inside buildings. Two-component resins are often the ideal choice to tackle this problem.

How the resin injection process works to stop rising damp:

1 – Assessment of the problem: Before starting treatment, it is essential to carry out a thorough assessment to identify the extent of the problem and identify the areas affected by rising damp.

2 – Surface preparation: The surface of the affected walls must be properly prepared; it may be necessary to remove existing plaster or coatings to access the affected areas.

3 – Drilling of injection holes: injection holes are drilled into the wall surface

4 – Mixing the two-component resin: Two-component resins, which may be epoxy or polyurethane resins, are mixed according to the manufacturer’s instructions. These resins are designed to react chemically once injected into the wall.

5 – Resin injection: The mixed resins are injected into holes drilled in the wall. The pressure of the injection forces the resin to expand and fill the cavities within the wall, creating an impermeable barrier against rising damp.

6 – Monitoring and curing time: After injection, the process must be closely monitored. The curing time of resins may vary depending on the type and environmental conditions, but it is essential to wait for the resin to solidify completely.

7 – Surface Restoration: After the resins have cured, the wall surface is restored. This may include repairing the previously removed coating or plaster.

Resin injections to block rising damp are an effective method of tackling the problem of rising damp in building structures. However, it is essential that this work is performed by experienced professionals, as it requires specialised knowledge and the use of appropriate equipment. Furthermore, it is essential to follow the manufacturer’s specifications for the preparation and use of resins.
