Damp problems in buildings, often caused by a failed or deteriorated Damp Proof Course (DPC), can be a serious issue. Fortunately, damp proof injection offers a fast, cost-efficient, and highly effective solution to tackle rising damp. We will explore how damp proof injection works and why it’s a preferred choice for dealing with severe water saturation in walls.

How Does Damp Proof Injection Work?

Damp Proof Course (DPC) injection is a specialsed process designed to prevent moisture from rising through brickwork via capillary action, which can lead to rising damp. The active component in this process is silane, which lines the capillaries within the masonry and creates a water-repellent barrier. Once installed, the damp proof injections can effectively combat rising damp for the lifespan of the property.

The Damp Proof Injection Process

At Anke Damp Proofing, we follow a meticulous process to ensure the proper installation of a remedial damp proof course:

  • Preparation: Our technicians begin by preparing the treatment area, both internally and externally. This may involve removing plaster and any fixtures and fittings, such as skirting boards and radiators, to provide access.
  • Drilling Holes: Small holes are then drilled horizontally into the wall mortar joint, approximately 40mm from the opposite face. These boreholes are where the damp proof course will be injected.
  • Injection: The damp proof course is injected into the boreholes. The injected chemicals penetrate the masonry surrounding the borehole, and the silane starts creating the water-repelling barrier.
  • Replastering: After the damp proof injection, our team re-plasters the affected areas internally using specific materials to ensure that any residual salts in the brickwork do not affect the new plaster.

Why Choose Professional Damp Proof Injection?

It’s crucial to choose a rated and approved contractor like Anke Damp Proofing for damp proof injection due to the potential pitfalls and mistakes that inexperienced tradespeople might make. 

Here are some common errors to avoid:

  • Drilling holes directly into the brick or stone instead of following the mortar line.
  • Applying a new damp proof course into pre-existing holes where a previous injection has failed.
  • Injecting a damp proofing course where an effective one already exists.
  • Injecting into a damaged or poor-quality mortar joint that needs repair.
  • Injecting when there are bridged cavity walls, which can lead to moisture passing through the damp proof course.
