snseal injection technology
vs. traditional injection methods
Cutting-edge, patented 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Outdated and ineffective for long-term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.
