Inner-wall Structural Waterproofing

Junctions and roofs are also places that should be checked for penetrating damp because water can seep into faulty mortar fillets, lead flashings, ridges or hips. Internal spillage is the result of any water that overflows from baths showers or sinks, water from birth pipes, water from leaky pipes or washing machine or appliances and even accidental damage.

Below ground damp could be rising damp. This type of damp is not as common as the other types, but it’s not impossible to see. In this case, floors become damp because  moisture has evaporated from below and is inhibited by vinyl sheet, rubber backed carpets, or various other coverings.

Damp Proofing Can Help Prevent

  • Rising / Penetrating Damp
  • Ingress of Water
  • Salt Crystallization
  • Plaster Breakdown
  • Damp Staining
  • Wet Rot / Dry Rot

How To Diagnose Damp on Inner Walls

To diagnose damp on inner walls you should check your roof during wet and windy weather to determine if a spot on the ceiling is a damp ceiling patch that is due to a leak in the roof or condensation from the weather. Broken slates, tiles and other debris on the ground or daylight seen inside lofts can also indicate potential roofing problems.

Check your plumbing to ensure there are no leaks. One way to check for leaks is to meter your water bill. If you have unusually high water bills or are constantly refilling the tank, you may have leakage.

When the internal walls of your home become damp, they create the perfect conditions for damp mould spores, and these spores are the worst kind of spores. Some types of damp mould can be deadly and they exist in an alarming number of homes across the UK.

What Are The Different Internal Damp Proofing Options?

The first thing to do when fixing damp walls is to investigate and find the root of the moisture. To identify where the moisture is coming from, you will need to do a thorough check of your home, both inside and out.

It’s not always easy to decide what to look for and the most ideal internal damp proofing methods and products to apply to make your home damp-free. One way to ensure that your home stays damp free is through the use of damp proof membranes. Damp proof membranes are made from plastics such as HDPE, which resist moisture and moisture vapour. The membrane surface is formed into a stud formation similar to an egg box. This surface creates air gaps that allow moisture to evaporate from the wall without leaving damp behind on the wall.

Another way to help ensure that your house stays damp free is through the use of damp proof paint. This paint is non-toxic paint. They can be applied to as serve as blockade moisture. Damp proof paint usually has a thick consistency and comes in black or white. Sometimes damp proof paint is referred to as water resistant paint or damp resistant paint. Once you’ve applied damp proof paint, stains should no longer appear on your walls. By using damp proof paint you will be able to achieve the desired look in your home. This paint also helps prevent mould growth which has been linked to a wide range of health problems, including respiratory problems.

Cementitious tanking was created primarily for use in walls below ground level, specifically the waterproofing of basements, tanks, and ducts. This type of damp proofing is applied to the internal face of the structure and can be used on many surfaces including concrete, stonework, brickwork and block work.

The application of renovating plaster, a plaster that is a premixed lightweight backing plaster, is another way to control dampness that passes through walls of older homes. The properties of a renovating plaster are similar to a 1:1:6 render (cement: line: sand), but in place of the sand, Perlite aggregate is used, which makes this plaster light and simple to use.

Finally, an anti-mould paint is a cost-effective way to block mould, and prevent damp on your walls. Anti-mould paint can prevent the unhealthy black mould from reappearing even when there is persistent condensation in a particular area. Anti-mould paint is made from a combination of modern paint technology and some effective biocides. The paint is specially engineered using the anti-mould biocide and paint film to make it water resistant yet durable, tough, and elastic. Anti-mould paint is ideal for walls, ceilings and homes as well as different types or categories of public and commercial properties. Anti-mould paint is completely washable and resistant to the effects of condensation once the application has been fully dried.

How Much Does It Cost To Damp Proof Inner Walls?
Most of the cost involved in damp proofing internal walls comes from replastering a decoration. Costs can vary widely between different areas and different suppliers. The costs will increase if you want the whole house or every wall treated.
