Rising Damp Treatment: Fixing Rising Damp

Rising Damp Treatment

Rising damp poses one of the most destructive threats to homes and buildings, especially older structures. Groundwater rises through masonry and walls, introducing moisture that triggers a musty, pungent smell—often the first tell-tale sign. This can cause asthma attacks and allergic reactions in those susceptible to such health problems. When the moisture carries soluble salts, it accelerates structural decay by corroding foundations and causing costly damage.

Since 1982, Tech-Dry has been a pioneer in answering the hard question of how to fix rising dampness in Australian buildings. In partnership with Victoria University, Tech-Dry researched and developed innovative silicone-based damp course treatments, culminating in the latest advancement: a water-based rising damp treatment cream designed for long-term protection and minimal disruption.

What is Rising Damp?

Rising damp is the natural phenomena of moisture containing ground salts rising by capillary absorption up a brick or masonry structure, e.g. masonry walls or fireplaces.

Fixing rising damp in an old house typically requires installing a new damp course to block salt migration and stop moisture from rising through the walls. However, this method involves significant cost and structural risk. As a practical alternative, Tech-Dry has developed more user-friendly and cost-effective treatments for rising damp. These products are applied directly into the wall, creating a water-resistant barrier that prevents both moisture and salt from migrating upward.

How to Fix Rising Damp?

Rising damp can be a serious problem in any home. If left untreated, it can cause extensive damage to the property and create an unhealthy living environment. There are a number of ways to treat rising damp, but the most effective and economical way is with a damp proofing injection cream.

Complete kits or individual cartridges of cream can be injected or hand-pumped into specially-positioned holes in the mortar course. This will provide a physical barrier to rising dampness, preventing moisture from entering the property.

What Causes Rising Damp?

Several factors contribute to rising damp, with one of the most common being the absence or deterioration of a damp-proof course. When this barrier fails, moisture can infiltrate the structure and rise through the walls. Faulty gutters and downpipes also play a role by allowing water to pool around the foundation, increasing the risk of moisture ingress.

Groundwater seepage presents another challenge. Water accumulating around the foundation can penetrate through cracks or gaps, intensifying damp conditions. To prevent further structural damage, it’s essential to identify and resolve the underlying causes of rising damp.

Anyone suspecting rising damp should arrange a professional diagnosis. A qualified inspector can assess the property, pinpoint affected areas, and recommend an appropriate treatment strategy to address the issue effectively.

How to Fix Rising Damp in Brick Walls?

Rising damp is a problem that affects many homes. It is caused by moisture rising up through the brickwork and affecting the internal walls and surfaces of your home. While it is not a health hazard, it can cause structural damage if left untreated.

There are a number of ways to fix rising damp, but the most effective solution is to install a new damp-proof course. This will create a barrier that will prevent moisture from rising up through the brickwork and into your home.
