What is Damp Proofing?

Damp proofing is a term commonly given to the process of installing a barrier to protect a property from unwanted moisture, which can enter from either the ground or through the walls.

If your property is suffering the negative effects of rising damp or penetrating damp, our damp specialists at Prokil can help. We can assess the extent of the problem with a thorough damp survey, before carrying out damp proofing treatment to suit the severity of the damp.

Why Do I Need Damp Proofing?

Damp proofing within your property is very important to ensure that you do not face long-lasting problems and potentially uncomfortable living conditions, such as condensation issues and rot.

Damp wall treatment is also important to meet current building regulations. All properties built today must have a damp proof course (DPC) in the walls and a damp proof membrane (DPM) in the floors, if they are of a concrete construction.

If you think you could be at risk of damp due to a missing or ineffective damp proofing, Prokil can ensure that your home is safe and comfortable to live in with damp proofing treatment.

How Do I Know If I Need Damp Proofing?

If you see signs of decorative spoiling, rotting timbers inside your property or feel that you could benefit from damp proofing and removal, Prokil can carry out a damp survey. Our fully qualified surveyors have a wealth of experience in damp proofing, allowing them to assess the initial cause and extent of the damp problem.

Prokil are able to use a wide range of tests, including non-intrusive radio frequency tests, intrusive calcium carbide tests and salt analysis, in order to correctly identify the form of damp and the correct form of damp proofing required.

Failure to have effective damp proofing can lead to a range of problems, which include:

  • Rotting timbers
  • Crumbling plasterwork
  • Condensation problems
  • Salt staining
  • Woodworm

What Types of Damp Proofing Treatments Are There?

Prokil offer a variety of damp proofing treatments depending on both the type of damp you have and the construction of the property. The different components which Prokil offer for damp proof work include:

Damp Proof Course

  • Installing a physical damp proof course in walls: A modern damp proof course usually comes in the form of a plastic material. Previous forms of damp proof courses have included flint, slate and bitumen.
  • Injecting a chemical damp proof course: Prokil use hand injection guns to insert chemical damp proof courses into walls to restrict the amount of rising damp.

Other Damp Proofing Treatments

  • Salt neutralisers: As moisture enters the substrate of a property, it often brings with it salts and minerals, which remain unless treated properly with effective damp proofing.
  • Specialist epoxy resins: If a concrete floor laid without a damp proof membrane or where the membrane has been damaged, Prokil can apply specialist damp proofing resins to protect your flooring.
  • Slurry tanking: Slurry tanking is another form of damp proofing, where a cement based product with water resisting properties is applied to floors and walls.
  • Specialist membrane systems: These membranes are often installed in basements but can also be used above ground as a damp proofing system.
  • Specialist render coats: A key component to remedial damp proofing work is to remove affected plasterwork and apply a specialist render coat. This contains salt inhibitors and waterproofing agents to effectively damp proof a property.
