When Penetrating Damp occurs above ground level, it is usually caused by bad, broken or damaged pointing or render. In the case of bad pointing, the simplest remedy is to re-point the affected area. This is very inexpensive and more often than not, works. When a house is rendered and the render is damaged, bigger problems are caused by water seeping into cracks that can be of any size. At this point the water will usually seep into the brick or block work behind the render and slowly penetrate through to the inside of the property. This is much more difficult to stop and is usually quite costly. We have Tanking Slurries and other water repellent chemicals that will often reseal the property and reinstate its water tight integrity. As always, we conduct a full site survey and will advise on the most probable cause of a problem and give solid advice on the best, most practical and cost effective solution.
