Rising Damp

Rising Damp is as destructive as the more common forms of damp and requires very specific attention and treatment.

As opposed to regular dampness, rising damp is a specific condition whereby ground water rises vertically through the pores of a wall structure, leading to deterioration of the solid structure. The natural process of evaporation means that rising damp rarely continues above a height of 1.5 metres, however given the right conditions the dampness can sometimes rise ever higher causing even more destruction. You can read more on these effects on our News page here

Aside from the aesthetic damage, Rising Damp can also cause health issues!

When the dampness breeds mould grows! it can also lead to structural damage due to the salts that evaporate from the damp wall surfaces.  They are deposited in the plasterwork around the damp areas. These salts build up and absorb moisture from the air, resulting in further damage to the wall structures.

This situation, when left untreated will damage the base of the affected wall and can affect the structural integrity of the building.

The natural process of evaporation means that rising damp rarely
continues above a height of 1.5 metres. Given the right
conditions the dampness can sometimes rise ever higher causing
more destruction. For more information on Mould, ypu can visit Health NSW Government Website here

TREATMENT FOR RISING DAMP

We have been working with home owners with Rising Damp Issues in Sydney for over 20 years. The most effective method for treatment of rising damp is installing a chemical damp proof course (DPC). This process is quicker, less costly and  intrusive than alternative methods. Other Methods often involve removing large sections of brickwork and wall coverings to get to the interior of the walls.

 

We use products from Techdry which include a chemical damp proof cream (Silicon based).  This is installed into the mortar and a salt retarder which is used in the render mix. On face bricks with no render, we can also provide salt extraction which involves using
the Westox Cocoon System.

Each job is different and we treat them that way.  There are variables such as:

blocked cavities and higher external ground levels.

In all cases we inspect the cavities using digital cameras to ensure that our DPC installation will not be “bridged out” by a blocked cavity. If there is higher ground on the opposite
side of the wall we will then need to implement negative waterproofing membranes.
