A surface filler hides a crack. Injection fills it from the back of the crack to the face, so it either bonds the concrete back together or seals it against water.
AWS Services has carried out crack injection on freeway barriers, tunnels, water recycling plants, and bio-reactors, as well as basements, lift pits, and slabs in commercial and strata buildings. Our technicians undergo continuous training to stay up to date with industry practices and technologies.
Bonds the concrete back together to restore structural integrity. Used to seal cracks, strengthen foundations, and repair concrete and masonry.
Best for: Structural cracks in walls, slabs, and barriers
Reacts with water and expands to seal cracks, leaks, and voids. Fast to apply, with very little disruption.
Best for: Leaking cracks, foundation stabilisation, and waterproofing
A low-viscosity gel used to seal fine cracks against water. Used in the road barriers at Lane Cove Tunnel.
Best for: Fine cracks in barriers and tunnels
The process we followed at Boneo Water Recycling Plant.
Injection packers are drilled along the crack to the depth needed.
The surface is pressure washed to remove algae and contaminants.
Resin is pumped in until the crack is filled through its full depth.
Packers are removed and the holes and any screed patched.
Stress cracks in the road barrier system injected with epoxy resin. All work was done at night, on time and on budget.
Joint remediation on two bio-reactors: new joint sealing systems, high-pressure epoxy crack injection, and water plugs to stop live leaks.
Crack injection, structural concrete repair, joint sealing, and waterproofing on failed walls and movement joints.

Epoxy restores strength, so it suits structural cracks. Polyurethane reacts with water and expands, so it suits leaking cracks. Some cracks need both.
Yes. Polyurethane injection is designed to seal cracks with water running through them, and fast-setting water plugs can stop flowing leaks first.
Usually not. Injection is done from the face we can reach, so basements, pits, and walls can be sealed from the inside.
An injected crack is usually stronger than the concrete around it. If the structure is still moving, the cause needs fixing too, which is why we look at it first.
