Do You Notice These Signs of Rising Damp?
- Flaking and Blistering Paint
One of the most visible signs of rising damp is flaking, blistering or powdery paint. Paint needs a dry surface to adhere, but damp works against this. As your porous masonry walls absorb water, the walls become drenched with liquid, salts and minerals. This damp disrupts the painted finish on surfaces, causing major damage to the protection and aesthetics of your walls.
- Structural Damage
Structural damage caused by rising damp can be easy to spot in your walls. After drawing up water, your masonry will contain trapped salts and minerals. Over time, these salts and minerals will expand, forcing their way out of the masonry from the inside. This will eat away at the mortar joins between bricks and disintegrate masonry into dust, turning your home’s walls into a crumbling mess.
- Mould Problems
Deep down in the foundations of your home, the moisture that your porous masonry has drawn from the ground has nowhere to escape. As a result, it doesn’t dry out naturally. This can cause the base of both your interior and exterior walls to develop a dark green or even black mould. If you spot mould localised around the base of your interior walls, the likelihood of rising damp is high.
- Yellow or Brown Tide-Like Stains
If your walls are showing yellow, wavy, tide-like stains, it’s likely you have a rising damp issue. When moisture in your masonry has a chance to dry, it leaves behind salts and minerals. These are what cause the ugly stains. But don’t be fooled–this is only surface-level drying. If you see stains, it’s a big warning sign that your walls are soaked through and damaged on the inside.

How does the Resin Injection process work?
FREE Structural Assessment
Our experts undertake a thorough inspection of your walls to confirm the presence and extent of rising damp. This ensures that the correct treatment plan is tailored to your home’s specific needs.
Step 1
Preparing For Injection
Before treatment begins, small holes (typically around 1 cm in diameter) are drilled into the affected wall, roughly 150mm above ground level. These holes allow DampBlock™ to be injected directly into the masonry, creating a protective barrier against moisture.
Step 2
DampBlock™ Injection
DampBlock™ is then injected into the drilled holes at high pressure. This water-based silicon formula fills the microscopic pores in the masonry, preventing capillary action, which is the process by which water rises up from the ground into the walls. The injection forms a long-lasting barrier that stops further moisture.
Step 3
Curing The Area
Once injected, DampBlock™ begins to set almost immediately, forming a gel-like substance that blocks moisture. It typically takes around 24 hours to fully cure. The rising damp is stopped immediately.
Step 4
Clean-up
Once the job is complete, we ensure all work areas are spotless, leaving your home looking as good as new.
Step 5

Have any questions?
We are here to answer any questions you may have Monday – Friday 9am to 4pm AEST. Give us a call on 1300 854 115.
How long will it take for my walls to dry after damp proof treatment?
We employ our damp proofing solution, DampBlock™, to counteract the effects of rising damp in your walls by blocking capillaries, reducing the walls ability to draw moisture upwards. After this process, the existing damp in your walls will generally take 6-12 months to dry out.
Do I need any follow-up work after damp proofing?
After the damp proofing process, your walls will start to dry. However, this can result in natural salt crystallisation and residual dampness on the surface. To prevent the surface plaster from deteriorating and the appearance of damp, an application of a salt-blocking solution is recommended, which we are happy to assist with and discuss during your assessment.
Will I have to vacate my property during the work?
Certainly not. DampBlock™ is non-hazardous and completely odourless, allowing you and your family to stay at home while we work.
What's your track record on completed projects?
Buildfix has successfully completed well over 10,000 projects across Australia over the past decade. This includes mostly residential projects, as well as some commercial and strata buildings.
