What is damp proofing?

Damp proofing is the installation of moisture control barriers to a structure (typically flooring or wall) to stop moisture from rising past the damp proof layer into the interior space. An example of damp proofing treatment involves a damp proof injection being applied to a property, which fills up space where the moisture occurs, soaks it up and prevents it from recurring.

What are the types of Damp?

There are three types of damp: condensation, penetrating damp and rising damp. Each type of damp requires a different method of damp proofing control and treatment. To ensure the right approach is taken to solve your damp problem, we recommend you only work with an experienced damp proofing company. Elite Builders London is an experienced damp proofing company you can count on.

Damp cases are never identical. This makes the diagnosis of a damp specialist surveyor essential. A damp survey this will prevent you from spending unnecessarily on a damp solution that doesn’t solve the underlying damp issue. A lot of the time all that is necessary is a proper survey to ascertain that the solution to the damp problem is inexpensive and doesn’t require an expensive damp proof course to be installed.

What causes damp?

Your property can develop a damp problem if there are channels for moisture to get into your property and/or there isn’t enough ventilation. The combination of these two factors will mean when moisture comes in, it doesn’t evaporate, which leads to the damp issue.

Damp can also occur when:

  • There is condensation – for example, water droplets that cover your bathroom mirror after a hot shower.
  • By penetration – moisture comes in from outside
  • By rising damp – water that goes up brick walls from the ground.
  • Damp penetration can be brought on by high ground levels, where exterior ground levels are built up at the same level or higher than the internal floor.
  • Cracked chimney stacks or broken roof tiles -this should be obvious but it is often overlooked but damp on internal walls or ceiling is usually a sign of a cracked chimney stack or a broken roof tiles.
  • Moss and vegetation – Climbing plants and moss on roofing soak up water. They also force the water away from drainage points like downpipes and guttering and prevent it from drying.
  • Other sources of damp include – watering fish tanks, washing the bathtub, doing the laundry, individual gas/ heating units without extraction, shower oil stoves and so on.

It’s as simple as this – if the air isn’t properly circulating inside a home, then moisture will not evaporate and this turns into a damp problem.

Rising damp treatments

Rising damp is probably one of the most common forms of damp issues, it is probably what you are most likely to have heard about. Rising damp occurs when cracks, holes and damages to a building’s brickwork draw water upwards; this is also known as capillary action.

Materials like brick are quick to absorb moisture from the ground. This moisture is then redistributed to other areas, which is why rising damp issues can damage large areas including the internal surfaces of floors and walls.

Like other types of damp problems, rising damp is best addressed as quickly as it is discovered to prevent its spread and reduce the cost of repairs. One of our in-house team of experienced surveyors at Elite Builders London will be more than happy to carry out a damp proofing survey of your property.

If the rising damp is mild, for most individuals, there is no need to worry. Although it may look unsightly and smells, the health risk won't be high.

The major difference between waterproofing and damp proofing is that damp proofing is designed to keep out moisture from the soil, while waterproofing keeps out liquid water and moisture.
