1800 18 20 20Engineered Water Ingress Solutions for Commercial, Industrial & Infrastructure Assets
Water ingress is one of the leading causes of concrete deterioration, reinforcement corrosion, asset degradation, and costly maintenance across commercial and infrastructure assets. Even small leaks can allow moisture to penetrate concrete, leading to structural deterioration, operational disruption, and reduced service life if left untreated.
At Rectify, we provide commercial leak sealing and water stopping solutions for buildings, tunnels, basements, reservoirs, water treatment facilities, utilities, and civil infrastructure across Melbourne, Victoria, South Australia, and projects throughout Australia. Our engineering-led approach identifies the source of water ingress before applying site-specific remediation methods that seal leaks, protect structural assets, and minimise disruption to ongoing operations.
Unlike temporary surface repairs, our solutions are designed to stop water at its source while helping preserve the structural integrity and operational performance of valuable assets.
What Causes Water Ingress?
Water penetration usually occurs because structural movement, ageing materials, or environmental conditions create pathways that allow moisture to enter the structure.
Concrete Cracks
Concrete naturally develops small cracks due to shrinkage, thermal movement, settlement, or loading. These openings allow water to travel through structural elements and eventually reach reinforcing steel.
Foundation Movement
Settlement and ground movement can place stress on foundations and retaining walls, causing new cracks or widening existing joints that permit water ingress.
Failed Waterproofing Systems
Over time, waterproof membranes and joint seals can deteriorate, reducing their ability to prevent moisture penetration.
Hydrostatic Pressure
Groundwater surrounding basements, retaining walls, tunnels, and underground structures creates continuous pressure against concrete. Even minor defects may eventually allow water to enter.
Construction Joints
Movement joints and construction joints are designed to accommodate structural movement, but if they deteriorate or lose their seal, they may become leakage paths.
Ageing Infrastructure
Older commercial assets are often exposed to decades of moisture, chemical attack, environmental weathering, and operational loading, increasing the likelihood of water ingress and concrete deterioration.
What Types Of Leaks Occur?
Concrete slabs and walls can form small cracks over time. This can be due to shrinking, poor workmanship or constant wetting and drying. Even though these cracks do not initially affect the structural integrity of concrete element, it can cause water leaks. This will lead to concrete cancer and spalling, which will compromise the structural capacity of the concrete elements.
Together with our engineering partners we are able to identify the underlying causes of the leaks and provide the appropriate rectification methods to push moisture out of existing concrete elements and provide a seal preventing the leaks from causing further damage to the structure.
Some structures requiring leak sealing:
- Concrete roof tops or suspended slabs exposed to water/rainfall
- Utilities and below ground assets including concrete sewer/drain pipes and pits
- Liquid storage tanks
- Basement retaining walls
- Tunnels
Scenario 1
A suspended slab with a roof top terrace and garden bed: If minor cracks occur, and the water in the rain garden leaks into the apartment below there are two options.
Conventional Repair
Remove all trees, vegetation and soil, and strip all waterproofing. Once all stripped, the area is to be cleaned, dried and waterproofing reapplied. Only once this is done, can the garden bed be reinstated, and terrace re-opened for public access. This requires permanent closure of affected area, it is also time consuming and expensive.
Our solution
Inject polyurethane resin into the crack through the slab from below; until the crack is fully sealed and the water leak has stopped, providing a permanent waterproof seal. This is not only non-invasive, it will only take a fraction of option 1.
Scenario 2
A basement wall on a site boundary has a leak through it. There are 3 options:
Conventional Earthworks
Expose the wall from the leaking side, this will require access to the neighboring property and the use of heavy machinery to expose the wall and re-apply waterproofing. This will require permits and permission from your neighbor, will be very costly and may take weeks.
Hide the Leak:
Create a false wall, or provide a seal on basement wall so no leaks are visible. However, since water is still entering the crack, this will lead to concrete cancer and further degradation and no ability to monitor the failure.
Our solution
High pressure inject polyurethane resin into the crack, not only sealing the crack but also providing a negative side waterproof seal.
