How do we apply damp proofing?

We apply Damp Proof Course (DPC)

We apply a number of techniques:

  • A specifically prepared cream or water-based substance is most frequently used to insert a chemically injected DPC. A member of our Damp and Mould Solutions team drills holes in the wall at the proper level, inserts the chemical, and seals the holes to prevent growing dampness.
  • Mortar DPC is primarily used on random stone walls. In order to apply a specially formulated cement-based mortar, our professionals will drill holes in the wall.
  • Electro-osmosis is another method of administering a DPC. This technique employs an electric charge that is earthed to the ground and affixed to the wall through wires. This is in order to reverse the polarity of the capillary action and draw the damp back into the ground.

We remove the plaster during damp proofing

When damp proofing a building, plaster must be removed since rising damp from the earth also contains hygroscopic salts, nitrates, and chlorides in addition to moisture.

Salts that are hygroscopic draw moisture from the air. These salts will contaminate the plaster inside the building, and the dampness of the salt-contaminated plaster can persist even after a repair DPC has been installed. During the course of treatment, it is crucial that contaminated plaster be removed and replaced.

Our experts will only remove what is necessary, which is typically one metre above floor level. The removal of one metre is necessary because, in general, moisture can rise up to one metre above ground level, depending on the site’s design and other factors. The appropriate repair for each damp scenario will depend on the property

Is my property damp proof?

Living in London means that it is essential for your home to have a damp-proofed construction that will guard against issues like penetrating damp, rising damp, and below-ground damp.

To stop moisture from entering interior living spaces, a damp proofing system is a moisture management barrier that can be applied to walls, floors, and the structure. In the UK, damp problems in buildings are very frequent, and damp remediation is one of the most often performed property maintenance tasks.

In order to prevent moisture from passing through concrete and masonry walls, a horizontal and vertical damp-proof barrier is needed in the proper location. A suitable damp proofing system can be installed by our Damp and Mould Solutions specialists for your property:

  • In order to prevent capillary action, which is damp rising from the ground, a damp-proof course (DPC) is a barrier that can be installed through a structure above ground level. Rising damp is a possibility if capillary activity is not stopped. To prevent rising moisture, a DPC layer is often installed in all masonry walls, whether the wall is a partition or a load-bearing wall.
  • A damp-proof membrane (DPM) is a type of membrane material that is used to stop moisture from entering a building. Typically, this is positioned beneath a concrete floor.
    In order to make the concrete itself moisture resistant, integral damp proofing in concrete entails adding water proofers to the concrete mix.
  • For resistance to non-pressurised moisture, such as rainwater, waterproof materials are applied as renders and surface coatings.

What causes damp?

Damp can happen for a variety of reasons, although it is most commonly caused by a failing damp proof course (DPC), inadequate ventilation, or poor property care.

Older housing were constructed entirely of porous materials with no attempt at damp proofing.

How to avoid damp in bathrooms

The easiest approach to avoid it is to keep the room adequately aired by opening a window or turning on the extraction fan whenever you shower or bathe.

Because of the constant excess moisture in bathrooms, damp and mould are very common.

Even if your bathroom has inadequate ventilation, there are still some things you can do to decrease condensation.

  1. Use a squeegee to remove extra water from the walls after you’ve taken a bath or shower. This can reduce the amount of excess moisture in your bathroom by up to three-quarters.
  2. Once a year, use a basic sealant to prevent moisture from leaking through the grout.

Penetrating Damp Treatment

Damp caused by rainwater ingress, due to defective external rendering, perished pointing, defective rainwater goods, defective roof coverings/flashings, Abutting solid structures, (yard walls etc.) and broken or worn out window seals.

Our surveyor will investigate the source of condensation within your property and explore the suitable long term solution. The results and feedback will be provided in a full written report, along with recommendations and details of the cost.

Rising Damp Treatment

Rising Damp is the vertical flow of groundwater through a permeable wall. The water rises through a series of interconnecting pores by a process loosely called ‘capillarity’ in other words porous masonry acts like wick.

Causes of rising damp is due to some of these factors; Slate DPC prone to damp from vibration and can deteriorate with age, becoming friable/brittle especially during the winter months. Lack of DPC at construction phase. Bridging of the DPC via blocked cavities, high ground levels and wall plaster
