Targeted Leak Sealing for Concrete Structures

Persistent water ingress can severely weaken concrete, compromise waterproofing membranes, and accelerate structural damage. WS Remedial Group delivers targeted leak sealing solutions that identify, isolate, and repair active leaks in concrete walls, slabs, basements and retaining structures. Using high-performance hydrophilic and hydrophobic injection systems, we stop water at the source preserving structural integrity, reducing maintenance costs and extending the lifespan of your asset.

Stop Active Water Ingress with Targeted Leak Sealing

Leak sealing protects your concrete structures from long-term water ingress that can lead to corrosion, cracking and membrane failure. At WS Remedial Group, we use precision injection techniques and high-performance sealants to stop active leaks in basements, retaining walls, tunnels and slabs. Our tailored solutions help maintain the integrity of your building envelope, reduce costly repairs, and extend asset life all while meeting Australian waterproofing and structural standards.

Resin Injection for Active Leak Sealing

Stop water ingress at the source with low- and high-pressure resin injection. Ideal for concrete joints, cracks and voids, this method seals leaks in basements, tunnels, and lift pits with long-lasting flexibility and durability. 
null

Leak Sealing for Retaining Walls and Basements

Our team specialises in sealing leaks through concrete and masonry walls exposed to ground pressure. We inject waterproof sealants that restore barrier integrity without the need for external excavation.

Water Ingress Solutions for Underground Structures

From podium slabs to basements and car parks, we apply high-performance polyurethane and acrylic gels to prevent long-term water damage, corrosion and spalling in below-grade concrete assets.

Waterproofing Injection for Expansion Joints

Protect critical movement joints in concrete structures with flexible waterproof injection systems. These solutions accommodate thermal and structural shifts while blocking active leaks. 
null

Curtain Injection Behind Failed Waterproofing

We seal inaccessible water pathways behind failed membranes or construction joints using curtain injection. This creates a watertight barrier without exposing the external wall or surface.

Leak Sealing for Slabs, Roofs and Podiums

We target horizontal surfaces like rooftops, suspended slabs, and planter boxes with advanced leak sealing techniques that eliminate moisture entry and preserve structural integrity. 

 

Protect Your Concrete with Specialist Leak Sealing Solutions

Persistent leaks can compromise structural integrity and accelerate concrete deterioration. At WS Remedial Group, we provide advanced leak sealing services that eliminate active water ingress and prevent future damage. Whether it’s basements, rooftops, retaining walls or tunnels, our expert team uses high-performance injection systems to restore water-tightness and extend the life of your concrete structures.
