Controlling Rising Damp throughout Beckenham, London, and the Surrounding Areas

Defend your property against damp with first-class services from Apollo Damp Proofing Ltd. Primarily seen in ageing properties, rising damp is caused when damp proofing has either failed or become ineffective over time. Our Beckenham-based experts carry out DPC injections to restore or replace damp-proofing courses throughout London and the surrounding areas. Unfortunately, rising damp can never be cured, but it can be controlled, so get in touch today to request a survey and quotation.

How Damp Progresses

Damp moves through capillary action, travelling across the mortar joints of the brickwork and eventually causing damage to the interior finishing of the walls. Moisture being driven up from the ground will also be transported along damaging hygroscopic salts. The salts are the white deposits you may have noticed on the outside of brickwork or the surface of interior plasterwork. If rising damp, or any form of damp, is left untreated, further damage could spread to interior floor timbers, resulting in major, expensive repair works.

Effective Controls

To control rising damp, the existing, broken-down damp-proof course needs to be replaced. This is achieved by injecting a chemical solution through holes drilled in the mortar joints. Due to the damaging hygroscopic salts that occur with rising damp, the internal plaster will need to be removed and replaced as part of the damp-proofing process.

DPC Injection Methods

DPC injections are a reliable modern equivalent to older, outdated treatments such as cement-based injections or crystalline products, which produced excessive salts and drying times. The most common and effective method is a chemical cream pressure injection. All our DPC injection methods are fully approved, and all equipment carries the British Standards trademark.
Our method of installing a new damp-proof course is as follows:
  • Remove the Skirting Boards and Wall Plaster to Reveal the Brickwork (The Removed Plaster Must Be 1 Metre High)
  • Drill 12mm Holes into the Mortar Joints, Starting from 150mm above Ground Level and Then at 12cm Intervals
  • Inject the Chemical Cream into These Holes until They Are Full
  • Once Injected the Cream Will Liquidise and Be Dispersed through the Mortar, Forming a Full, Horizontal Damp Proof Course
  • Apply a Specialist Render and Plaster System to Finish
