Rising Damp Waterproofing Solutions – Brisbane – Queensland

Rising Damp Treatment


Rising Damp is a phenomenon where moisture from the ground is wicked up through the masonry and building materials by capillary action, resulting in moisture appearing to rise from the ground.


Rising Damp is one of the many types of water ingress issues our clients face.  The issue with rising damp is that it often goes on inside walls undetected for a long time, slowly damaging the structure of buildings.  Early visible signs of rising damp may be subtle enough not to raise the alarm of the property owner until the extent of the problem is clearly evidenced by deteriorating stumps, footings, masonry and building bricks.


A musty smell may be one of the first sign of rising damp that you notice. The wet areas affected by rising damp are typically found behind skirting boards. The detection often happens when someone opens the wall and finds that the structure behind it is rotten.
Rising damp can also be identified by a characteristic whitish powdery tide mark (Efflorescence) on the lower section of affected walls. This tide mark is caused by salt being brought through to the surface by the effects of evaporation. These salts accumulate at the “peak” of the rising damp.



What are the Common Signs of Rising Damp that you can look out for?

  • Tide marks of salts / raised white deposits
  • Dark patches on walls that can be damp to touch – Determine that the brickwork/masonry is actually wet and not just the plaster or wallpaper.
  • Stained or crumbled plaster, peeling wallpaper and blistering paint around the floor level
  • Damp and musty smell.
  • Discolouration and black spots of mould
  • Decaying timber such as skirting boards, floorboards, floor joists.
  • Deterioration of mortar joints


Mould or damp patches are not always visible and you may have hidden mould or damp:

  • There is a mouldy/earthy odour
  • There is regular condensation indoors
  • The home feels regularly humid.


Rising damp problems often occur because a Damp-Proof Course (DPC) has not been installed or that the DPC is faulty due to age or incorrect installation as shown in our illustration.

Our team will: assess the cause of your rising damp issue; solve the problem/s that have allowed the penetration of moisture to occur; and properly waterproof the area. Our injectable damp-proof course treatment (chemical DPC injection) will protect your structure from damage that can result from rising damp.  Happily, we can often repair any damage dampness may have already caused.

Our treatment of Rising Damp involves injecting a damp-proof course (DPC) into a location where no physical DPC is present.


  • We drill holes at regular intervals.  The distance between the holes will vary depending on certain variables such as the type of brick, the extent of the cavity and how far the product travels when injected.


  • We inject our own PWR chemical into the wall creating a Damp Proof Course (DPC). This barrier prevents moisture from seeping up through capillary action, and thereby protects the brickworks from further damage caused by rising damp.


  • The product cures clear/invisible.  In some cases, however, it may slightly darken the area where applied.  White spirit is used as a carrier so it does have an odour, but this quickly dissipates.


  • The product works by lining the pores of the substrate to reduce their size – water can no longer pass through, but air still can. The method can be combined with our other systems to treat moving cracks, wide gaps or voids.

There are 3 main Categories of Dampness in buildings, of which Rising Damp is one

There are many causes of excess moisture in the structure of a building, such as leaking pipes and damage to gutters and roofs. However, a high proportion of damp problems in buildings are caused by rain penetration, condensation or rising damp.

Many of the visual signs of the three main categories of dampness in buildings may look quite similar to the untrained eye. This is why penetrating damp and condensation can be mistaken for rising damp or vice versa.
