Controlling Penetrating Dampness

Mitigating the impact of lateral water movement through walls

Penetrating damp is the horizontal movement of water through walls. Our survey will investigate the source of moisture – we need to be able to exclude poor maintenance which can easily be corrected such as defective gutters, down-pipes, poor pointing or plumbing leaks.

In considering the most appropriate solution for penetrating dampness, our first suggestions will usually be to reduce any high ground levels surrounding the affected structure. If this is not possible our Stonehouse surveyor will consider and select one of the following internal solutions:

  • We can utilise our own plaster mix to ‘tank’ the internal wall surface, specifically using Stonehouse Premix No.5 with a higher concentration of Stonehouse Pro-proof R additive. We link the walls and floor with a junction at this vulnerable position
  • Alternatively, we may suggest using a cementitious slurry system such as Vandex BB75 in conjunction with Stonehouse Premix No.5 in areas of high risk

If there is a well-ventilated timber floor, we often choose a cavity drain membrane system, extending the membrane down into the sub-floor void.

We offer long-term guarantees for all categories of works which are frequently in conjunction with the installation of a damp-proof course.
