What is dampproofing? And how does it work?
Damp proofing differs from waterproofing in that it protects the surface from moisture and water vapour typically coming from damp ground, while waterproofing protects from these as well as from heavy exposure to liquid water.
Waterproofing is usually selected for foundations in areas with very high water tables or continuous rainfall where the foundations are likely to be exposed to liquid water often.
Damp proofing is sometimes used on foundations in very dry areas where the foundations and exterior walls are unlikely to come into contact with liquid water.
A popular choice though is to waterproof foundations and then damp proof the structure of the house above ground for improved moisture resistance.
How is it done?
Damp proofing is done by cleaning the surface to be treated with great care (before moisture control applied), as any dust could cause the product to lift, allowing damp in. The damp proofing course or product is then carefully applied to all parts of the surface by a waterproofing professional at exactly the right thickness, and allowed to dry completely before a second coat is added. Once the second coat has been added it must be given time to dry entirely before the surface can be declared damp proof and paint or coverings can be applied over the treatment.
Using impermeable material, this will prevent moisture transmission into your solid concrete floor, concrete slab, skirting boards, outer wall and masonry walls.
Say goodbye to unwanted moisture and damp problems with a damp proofed continuous barrier to prevent structural dampness during rainy weather, or the wet summer season.
Why you need it and how it will benefit you.
Damp proofing will protect your home from two types of damp, rising damp and penetrating damp. Rising damp is caused by water rising through the walls (e.g. concrete walls or masonry foundation walls), and is usually caused by exposure to soil moisture at ground level or high water vapor levels. Penetrating damp is caused by an issue with a downpipe or gutter system where water is constantly dripping onto the walls, never giving them time to dry out.
It can also be caused by frequent exposure to rain. Without damp proofing either of these types of damp can cause problems for you and your family. The most dangerous of these is the formation of mildew and mould which can cause various health problems such as aggravating asthma in people who already suffer from it, or causing breathing difficulty in people who don’t.
The presence of the spores in the air released by these organisms is what causes these breathing difficulties. Other inconvenient and costly problems are the damage that damp will cause to your paint and plaster, meaning more frequent repainting and re-plastering.
Correctly installed foundation drains will allow for proper surface drainage and will protect your interior spaces, building walls, interior walls and exterior walls.

Is damp proofing the same as waterproofing?
A subtle difference in damp or waterproofing exists. Dampproofing is meant to keep out ground moisture while waterproofing mainly keeps out moisture and liquid water. Dampproofing is a coat usually using asphalt in its application on the exterior of walls.
Does damp proofing really work?
When properly installed they’re 100% effective. No one suddenly fails. Please avoid the option to install a Chemical Damp Proof course in one of these buildings. One small inquiry almost certainly will find a water leak, usually internal, that are usually covered by your Building Insurance.
Can you do damp proofing yourself?
Even installing a moisture resistant membrane (DPM) of the plastic sheets mesh variety can be considered a DIY proofing solution. Once again they also feature the available damp proof membrane kits that may do the job.
How do you damp proof a wall?
The easiest way to dampproof a room is for a wall to be sprayed with a damping resin or epoxy coating. You can also use plastic sheeting on the exterior of wooden walls, or plastic to fill in gaps in masonry to prevent damp.
