Damp Proofing for Your Home
There are a number of ways that damp proofing can be carried out, which will include either of the following options or even a combination, if that is what is required to solve the damp problem.
- Installation of a chemical injected damp proof course together with associated re-plastering
- A structural waterproofing system incorporating a damp proof membrane and possible sump pump.
- The use of conventional cementitious tanking system.
At Pennine Preservation, we are experienced in damp proofing walls, basements and cellars in properties of all ages and size.
We offer guarantees with our damp proofing treatments for both rising damp and penetrating damp for Huddersfield Halifax, Bradford homes.
Damp Proofing Solutions
The use of a low odour water-based silicone injection is generally regarded as the most effective type of damp proof course to prevent moisture rising through a wall and leading to rising damp.
Installation of damp proof course:
Where rising damp is diagnosed, Pennine preservation’s will install a remedial damp proofing course in Huddersfield Halifax, Bradford using their PAM Cream Silane Diffusion system, the very latest in damp proofing technology.
This involves the introduction into the wall of a concentrated thixotropic silane/siloxane ,‘cream’ to form a barrier against rising damp. As the cream slowly diffuses, it releases a silane vapour which reacts with the silica in the masonry to form a water repellent resin.
No liquid is involved so the wall is quicker to dry out and it is not injected under pressure which means that there are no problems with party walls.
- Low hazard, non-caustic and solvent free
- Non-flammable and virtually odourless
- Recommended for brick or stone
- Suitable for walls of any type and thickness
- For both internal and external use
Following the insertion of a damp proof course it is common for re-plastering to be required. Any new plastering has to prevent damp and salts present within the wall migrating onto the internal wall finish.
The most common approach to re-plastering is using a dense sand and cement render as a backing coat incorporating a waterproof additive. Once dry, a gypsum skim coat is applied to give a smooth finish.
When the existing plaster is removed, there may be a lot of dust. We advise that adequate steps are taken to remove or cover furnishing for protection.
Following re-plastering a minimum of at least two weeks must elapse before the new plaster can be decorated and all areas need to be visibly dry.
At this time decoration should only be with a water based permeable emulsion, vinyl paints should not be used.
Permanent decorations such as wall papers can be applied when the wall is fully dry, which can take up to a year and in some cases much longer.
