Damp Proofing Services For Chichester
& Bognor Regis


So what have Top Joints been up to within our damp proofing sector in Chichester and Bognor Regis? As you may know we are currently deep in condensation season so we have been carry out a lot of damp proofing and condensation surveys / works in the Chichester / Bognor Regis area, from PIV (positive input ventilation) instalments to full damp proofing regarding rising damp / penetrating damp projects and also structural repairs, steel beam installations.





Recent PIV Installation



PIV installed today (positive input ventilation) for a client in Chichester due to a condensation issue. Our client will now have a constant flow of fresh air entering the property along with eliminating the condensation issue and eliminating musty smells...











Current Damp Proofing Project



This is a few images of a current damp proofing project we have going on for a client in Selsey, near Chichester. Plaster hacked off at 1.2m due to a rising and penetrating damp problem, we go the extra height as sometimes moisture can be forced up above the recommended 1 meter point. Lots of making good to do to the brickwork now before our specialist damp proofing product can be applied.











What is rising damp?
Rising dampness is caused when water from the ground spreads into the brickwork by means of capillary action rising through fine pores in the walling and masonry. The height of the rising dampness will be influenced both by the amount of moisture in the soil, the height of the water table and any leaks in below ground level drainage. The maximum height that would be expected is 1200mm under normal conditions.



What is penetrating damp?


Penetrating damp, another name is lateral damp, is the result of water penetrating from the outside of a building and into your property causing problems to exterior and internal walls if not recognised and dealt with at an early stage. Unlike rising damp, penetrating damp can happen at any level within the property including roofs, ceilings and walls, it is most commonly caused from leaky pipes, broken gutters, poorly maintained brickwork, deterioration of mortar joints showing cracks which over time can become damaged or need re-pointing, crack stitching may be needed in some cases, water management systems are also a typical cause of penetrating damp. It is a very common problem found within older properties that have solid walls, newer properties tend to have much more protection from penetrating damp through the use of cavity walls and the way they are built these days, therefore new builds are less likely to suffer from this type of damp problem, although situations can arise in modern building.
