What is Rising Damp
Rising damp is a form of moisture intrusion that occurs when groundwater travels upward through porous building materials, such as brick, stone, or plaster. This happens due to capillary action, where water is drawn up through small pores in the material.
Signs of Rising Damp:
Damp or stained walls – (especially near the bottom, roughly, up to about 1.5meter high)
Peeling paint or wallpaper
Crumbly or deteriorating plaster
White, powdery salt deposits (efflorescence)
Musty smell
Warped wood or rotting skirting boards
Causes of Rising Damp:
Lack of damp-proof course (DPC), a protective barrier in walls)
Failure of a damp-proof course (DPC), a protective barrier in walls
High groundwater levels
Defective external surroundings of a building (penetrating damp)
How to treat Rising Damp
Install or repair a damp-proof course.
Apply waterproof coatings or sealants.
Improve air circulation around the property.
Improve defective surroundings of a building.
Use specialist injections to create a chemical barrier against moisture.
Treatment to stop Rising Damp
At T.A Damp Proofing, we provide comprehensive solutions for Rising Damp. We inject silicone emulsion cream and or liquid into the mortar. The chemicals are formulated with silane/siloxane-based compounds, which are highly effective at repelling moisture.
The injected chemical works by diffusing through the pores of the bricks and mortar. As the active ingredient spreads within the masonry, it reacts with the natural minerals in the wall to form long hydrophobic (water‑repellent) molecular chains. These chains line the capillaries of the wall, significantly reducing their ability to absorb and transport moisture.
When the correct volume of chemical is applied, these hydrophobic bonds create a continuous and unbroken damp proof course (DPC) across the entire length of the wall. This internal transformation forms a durable water‑repellent barrier within the masonry, preventing rising damp and helping to control moisture movement.
Structural Damage
Prolonged exposure to moisture can weaken and damage building materials. Damp can lead to rotting of wooden structures, corrosion of metal components, and deterioration of masonry and concrete. Over time, this can compromise the structural integrity of your house.
Unpleasant Odours
Damp often results in musty or unpleasant odours in your home. This may be particularly noticeable in basements, bathrooms, cabinets or areas with poor ventilation
Damage to Interior Finishes
Damp can cause damage to interior finishes such as paint, wallpaper, and plaster. Damp can lead to peeling paint, bubbling walls and crumbling plaster, requiring repairs and reapplication of finishes.
What is a Damp Proof Course
Damp proof course (DPC) is a protective, waterproof layer built into the walls of a property to prevent moisture from rising through the masonry. It acts as a barrier that stops groundwater from travelling upward through the tiny capillaries in bricks and mortar—a process known as rising damp.
Most problems with rising damp occur when:
No damp proof course was ever installed, or
The existing DPC has become damaged, bridged, or ineffective over time.
Without a functioning DPC, moisture can rise through the walls, leading to:
Structural deterioration
Damage to plaster, paint, and finishes
Mould growth
A properly installed or restored damp proof course repels water and protects the building from these issues, keeping the internal environment healthier and the structure more durable.
Signs of Rising Damp
Rising Damp
Without a DPC, moisture from the ground rises through the walls by capillary action. This dampness can travel up to about 1.5 meters above ground level.
Mould Growth
Damp walls create the perfect environment for mould and mildew, which can lead to respiratory problems and allergies.
Unpleasant musty odours.
Structural Damage
Crumbled plaster, blistering and peeling paint – Moisture weakens wall finishes.
Salt deposits – Minerals from the ground accumulate on walls, causing powdery white stains (efflorescence).
Weakened masonry & timber – Continuous dampness can cause bricks and mortar to deteriorate, and timber elements to rot.
Heat Loss and Energy Bills
Damp walls lose heat faster, making it harder to maintain a warm interior, increasing heating costs.
