How to stop rising damp?

 

Depending upon the build of property and the issues causing rising damp, different methods can be used.

​

Internally, vertical membranes can be applied, or fitted. Cement based tanking solution, such as Vandex, has been the preferred method for the last 40 years. The recent introduction of Newton membrane, a plastic membrane has provided an alternative. These applications are guarantee-able upto 10-30 years depending.

​

Alternatively, or as well DPC (Damp Proof Course) liquid injections can be applied. Effectiveness, can vary according to the building and its issues. Generally, used in-conjunction with vertical membranes.

 

Ground levels, externally, should be checked that they have not risen, in particular, with the introduction of raised patios and flower-bed which can cause moisture to go above the DPC (Damp Proof Course) line that was initially fitted in the brickwork during the build.

How to stop penetrating damp?

​

Cracks in the external rendered walls should be filled and brickwork repointed where mortar is missing. Some buildings might require having the render removed and new render applied.

​

Rainwater systems should be checked and roofs checked for leaks.

​

Internally, damp proofing can be fitted - but ideally problems should be sorted internally.
