Seal Smart injectable waterproofing delivers longer-lasting, stronger protection than foam or poly membranes. It outperforms across wall cracks, lift pits, secant piles and sheet piles. “
By penetrating deep into cracks, joints, and voids within the structure, Seal Smart forms a permanent, flexible seal that moves with the building rather than breaking down over time. Unlike traditional foam or surface-applied systems that can shrink, degrade, or fail under pressure, Seal Smart reacts within the substrate itself, stopping water at its source. This makes it ideal for high-risk and hard-to-access areas where long-term reliability is critical, delivering a durable waterproofing solution that reduces repeat failures, minimises disruption, and extends the life of the structure.
Is there water pooling on the ground? Are there stains on your walls? Do you have mould or peeling paint? Are there rust stains? If you answered yes to any of these, it’s likely you have a leak and should contact Seal Smart for a consultation.
Water ingress refers to unwanted moisture entering your structure, while water egress is the controlled removal or drainage of water. Proper waterproofing addresses ingress to protect your building from damage.
Injectable waterproofing works across a wide range of concrete structures, including basements, lift pits, rooftops, podiums, foundations, construction joints, underground tunnels, secant piles, car parks, ramps, and retaining walls.
Our revolutionary Seal Smart Injectable Waterproofing Sealant penetrates cracks, joints, and porous concrete, creating a permanent barrier from within. It works in combination with surface membranes to provide a dual layer of protection, stopping leaks and reinforcing the surrounding structure.
Injectable solutions can be applied to both new and existing structures, including high-pressure environments like basements, underground tunnels, retaining walls, car parks, ramps, secant piles, and more.
Cutting-edge, product and system designed specifically as a water ingress solution
Outdated and ineffective for long-term
leak prevention.
Ultra-low viscosity liquid injected at high-pressure, moving like water to fully penetrate and seal cracks and voids. Can be injected underwater.
Foam/Poly does not penetrate deeply or seal the full extent of the crack. Can not be injected underwater.
Cures into a durable, flexible and a very adhesive solid seal.
Expands into a rigid foam block with zero flexibility, leading to failure over time.
Permanent solution — does not degrade or break down.
Temporary fix — product deteriorates and requires constant reapplications.
Can permanently fix any water ingress issue, where previous foam injections have failed.
High failure rate, requiring repeated maintenance and touch-ups.
Fewer drill holes needed for injection, reducing risk of additional leaks and preserving the structure.
Requires numerous drill holes, increasing the likelihood of further water penetration.
Clean injection and crack site with minimal disruption and zero-mess finish.
Injection packers remain permanently embedded in walls, resulting in corrosion, leaving visible residue and noticeable foam leakage.
Non-toxic, eco-friendly, meets NYC VOC environmental standards and has fire-resistant properties.
Toxic, carcinogenic and can degrade over time, potentially contaminating waterways.
Can be applied at any stage of construction from foundation work to post-construction repairs.
Typically applied as a last resort after basement completion.
Build-in mould and micro organism resistance for long-term protection
Prone to mould growth and microbial infestation over time.
Only certified in-house technicians apply the product ensuring consistent quality and performance.
Any contractor or handyman can use and install resulting in inconsistencies.
Backed by a product performance guarantee and warranty.
No guarantee or warranties — results vary and often fail.

Seal Smart delivers engineered waterproofing and leak-stopping solutions for a wide range of industries, from large-scale residential developments to complex commercial and industrial environments. Our experience includes basements and foundations, car parks, lift pits, podium decks, and critical concrete structures where water ingress cannot be tolerated. Each project is assessed individually to ensure the most effective combination of injectable and membrane waterproofing systems.
We provide specialist waterproofing solutions for rail infrastructure, protecting tunnels, platforms, retaining walls and trackside structures from water ingress and long-term deterioration.
Our systems safeguard commercial buildings such as offices, retail centres and mixed-use developments, minimising disruption while delivering durable, warrantied waterproofing solutions.
We work on large-scale residential developments and apartment blocks, resolving leaks in basements, foundations, car parks and communal areas to protect both structure and living spaces.
Seal Smart treats cracks, joints and concrete defects in bridge structures, helping to prevent water penetration that can lead to corrosion, freeze–thaw damage and structural degradation.
Our waterproofing solutions are suitable for water-retaining and water-adjacent structures, including treatment facilities, tanks and chambers where reliable sealing is critical.
We protect power substations and associated infrastructure from water ingress, reducing the risk of equipment damage, downtime and safety hazards.
Seal Smart provides specialist waterproofing for tunnelling projects, protecting underground structures from water ingress, hydrostatic pressure and challenging ground conditions.
