“To understand what Rising Damp is, you first need to know what Rising Damp is not.”
Rising damp is frequently confused with condensation, leaking plumbing, or external water ingress.
Treating the wrong issue leads to ineffective repairs and recurring damage.
Correct diagnosis requires understanding how moisture and salts move through masonry and identifying whether the moisture source is truly rising from the ground.

“We specialise in diagnosing and treating true rising damp in masonry buildings across Sydney & NSW.”

Rising Damp Under A Microscope
Here’s a list of myths that most contractors don’t want you to know.
This video shows salt extracted from brickwork into a paper medium then studied under a microscope.
Rising damp damages masonry because salts migrate into the brick or stone and crystallise inside it.
As moisture evaporates, the salts form crystals between the tiny mineral particles that make up the masonry.
These crystals expand and force the particles apart, gradually breaking the material back down into sand and dust.
Over time, this process can lead to significant deterioration and structural damage.
We never skimp with our chemical injection product, we overdo it
This video showcases a Rising Damp Treatment in progress
This is a Silonexx rising damp injection treatment.
The injected silane-based fluid migrates through the masonry pore structure and chemically bonds with the mineral substrate, converting the masonry itself into a water-repellent barrier rather than relying on surface coatings.
The treatment is injected deep into the wall to ensure full penetration and maximum saturation within the masonry matrix.
Injection continues until refusal, indicated by material emerging at the masonry surface, confirming complete pore filling and barrier formation.

Pre-Purchase Reports
Pre-Purchase Building Inspection for Waterproofing & Rising Damp.
Find the hidden water problems that the sellers don’t want you to know about!
Don’t buy a lemon.
Know what’s wrong and estimate how much it will cost to fix before you buy.
Rising Damp and waterproofing issues can often be concealed — and even experienced building inspectors may overlook them. These problems can be very costly to repair and frequently catch homebuyers off guard.
As a Rising Damp Specialist, I use advanced diagnostic tools and years of experience to identify hidden issues that others miss, giving you clarity and confidence before purchase.
***By law, a vendor must disclose known property issues. However, many simply claim ignorance — “Oh, what a surprise, I’ve never seen that before!”
Even if the seller won’t negotiate on price, at least you’ll know exactly what you’re committing to and how much it will cost to fix.
I charge a small fee for pre-purchase Rising Damp and waterproofing building inspections — $420 plus GST — but it’s a small price for genuine peace of mind and expert insight.

FAQs
Does chemical injection actually stop rising damp?
Yes. When rising damp is correctly diagnosed and properly treated, chemical injection stops moisture rising through the wall by forming a permanent barrier within the masonry.
How do you confirm it’s true rising damp?
We start by confirming the moisture source. Rising damp has a specific pattern and salt behaviour, and we carefully rule out condensation, plumbing leaks, and other moisture issues before recommending treatment.
How long does rising damp treatment last?
A correctly installed injection system is designed as a long-term solution. Once the barrier forms inside the wall, it doesn’t break down or wash out under normal conditions. Our product has a 27 year warranty.
How long does it take for walls to dry after treatment?
Moisture is stopped immediately, but walls dry gradually. Depending on the wall and conditions, this can take weeks to several months as the wall dries naturally.

Experience
Broad experience within construction for over 30 years.
Jason (our Director) began working in the building industry at the age of 12, installing skylights alongside his father. In the early stages of his career, he gained experience in the following trades:
- Plumbing
- Drainage
- Demolition
- Commercial concrete polishing
- Handyman services
- Carpentry
- Roof replacements
- Bathroom waterproofing
- Roof waterproofing
- Basement waterproofing
This broad exposure across multiple construction disciplines gives us a clear advantage when assessing complex moisture-related issues, allowing for fast, accurate diagnosis through cross-referencing real-world trade practices.
Manufacturing
The science of rising damp is something Jason (our director) has a deep fascination with. If you ask, he’ll explain the chemistry of how rising damp occurs.
From this foundation, he began researching rising damp treatment chemistries used throughout the world, and the result of more than three years of research led to the in-house manufacture of our own rising damp injection fluid.
Our rising damp injection system was developed using a specialised chemistry-sector AI engine designed to model and optimise molecular behaviour within masonry pore structures.
This advanced development process allows us to deliver a highly predictable and consistently performing rising damp treatment system.
