The “Green” damp control

May 17, 2011

"Green" damp control vents

I’m now noticing more and more properties that have been installed with the so called “green” damp cure from Holland. This involves installing specially designed clay vents into a masonry wall.

The idea is that external “dry” air circulates through the device and absorbs the moisture entrapped within the masonry. The air then leaves the vents, taking with it moisture that was allegedly making the wall damp.

I don’t want to comment on the effectiveness of this method of damp control, but before a strategy can be established for drying a damp wall you first have to find the dampness defect(s).

Finding the dampness defect(s) requires a thorough inspection of the building to identify all possible causes of the dampness.

Vents also installed at high level.

.

Failure to identify the defect(s) causing the dampness may result in costly and unnecessary work being done to your home. For example, installing costly vents will not fix the leaking gutters.

Again, please take care and if it sounds too good to be true, it probably is!

  1. Holland Damp are no longer in business, the best green solution on the market currently is the Schrijver System which is superior to Holland anyway. The Schrijver system actually works very well.
