The team at Waterstop Solutions are experts in Rising Damp Waterproofing Treatment. Our services are offered in Sydney and outlying areas in the New South Wales Region, with offices in Sydney and Brisbane.

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 Penetrating Water Repellent (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 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.
