Rising Damp Treatment

Home \ PU Injection \ Rising Damp Treatment

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 and building bricks.

 

Rising Damp is a phenomenon where moisture from the ground is sucked upwards while being absorbed into a wall, resulting in moisture appearing to rise from the ground. Even seemingly waterproof areas can battle moisture issues as water collects in walls through rising damp.

 

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 which can result from rising damp. Happily, we can often repair any damage dampness may have already caused.

 

 

Treatment of Rising Damp – Waterstop Solutions Injectable DPC (Damp-Proof Course)

 

 

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 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 2 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.
