Damp Proofing Services
Damp proofing is a significant aspect to consider when it comes to maintaining a healthy and secure home. Dampness in your home can lead to a range of issues such as mould, rot, and unpleasant odours. It can also adversely affect the structural integrity of your home’s walls and foundations. To avoid these problems, it is crucial to get a professional to assess your home’s moisture levels and perform damp proofing measures if necessary.
Damp proofing can be carried out in several ways, such as the installation of damp proof membranes, coatings, or injection treatments. The sooner such measures are taken, the easier the job will be, and the less impact it will have on the overall structure of your home. By investing in damp proofing, you can ensure the well-being of your family and preserve the value of your property. Don’t overlook this essential aspect of home maintenance and seek professional guidance for the best solution for your specific needs.

Frequently Asked Questions
Damp proofing prevents moisture from the ground or walls from rising through capillary action, typically via a damp-proof course (DPC) or damp-proof membrane (DPM). Waterproofing, on the other hand, blocks both water and vapor, and is used where there’s hydrostatic pressure (like underground basements). Damp proofing controls moisture; waterproofing offers full water resistance.
Signs include peeling paint, blistering plaster, musty odours, mould growth, discoloured patches, and a cold, clammy feel to the walls. In basements, visible water stains or pooled water on floors are strong indicators. A professional inspection can confirm the cause and recommend the correct treatment.
Rising damp is caused by groundwater moving up through brick or concrete walls via capillary action, often due to a damaged or missing damp-proof course. Treatment usually involves injecting a chemical DPC into the wall at the correct height to form a new moisture barrier. Damaged plaster may also need to be removed and replaced.
Not necessarily. While external water ingress due to poor drainage, cracks, or hydrostatic pressure is common, condensation from poor ventilation can also cause dampness. A damp specialist will assess whether it’s structural, drainage-related, or humidity-based before recommending a solution.
High-quality damp proofing solutions can last 20–30 years or more if properly applied and maintained. Chemical DPC injections typically come with 10–25 year guarantees. Longevity also depends on ongoing maintenance of external drainage and gutters to prevent water buildup near walls.
Costs vary depending on the extent of the problem, wall or basement size, and treatment type. On average:
Chemical DPC injection: R350–R600 per linear metre
Basement tanking or waterproofing: R1000–R2000+ per square metre
Always request a site inspection and detailed quote before committing.
Yes, many damp proofing methods, like chemical injections, internal waterproofing slurries, or membrane tanking, can be applied from the inside, especially for basements or areas with limited external access. However, external work may still be necessary if structural drainage issues are involved.
Most internal wall damp proofing jobs take 1–3 days, depending on wall length and whether re-plastering is needed. Basement waterproofing systems can take 3–7 days or more. Drying times for re-plastered walls can range from 2 to 6 weeks, depending on conditions.
It can eliminate the root cause if the mould is due to excess moisture from rising or penetrating damp. Once treated, and after thorough cleaning or re-plastering, the area should remain mould-free, provided ventilation and drainage are also addressed. Mould from condensation may require improved airflow or dehumidification in addition to damp proofing.
In most cases, no planning permission is required for damp proofing work. However, if the property is a listed building or in a heritage zone, additional approvals may be needed. It’s always best to check with your local municipality or heritage body before starting work.
