Resin Injection & Crack Sealing Techniques
We use advanced crack injection resins and proven sealing methods to permanently repair structural cracks in concrete walls, floors, and foundations.
Low-Viscosity Epoxy Injection
For static structural cracks, we inject ultra-low viscosity epoxy deep into hairline fractures, creating a permanent structural bond stronger than the original concrete. Ideal for basement walls and structural elements.
Polyurethane Crack Injection
For active water leaks and moving cracks, we use expanding polyurethane resins that seal and flex with structural movement, stopping water ingress immediately in wet conditions.
Surface Crack Routing
Mechanical cutting and preparation of crack edges to create clean channels for resin injection, ensuring maximum penetration and long-term structural bonding.
Injection Port Installation
Precision placement of injection ports along crack lines, allowing controlled resin flow from the deepest point upwards, ensuring complete crack filling and structural integrity.
Flexible Sealant Systems
Application of movement-tolerant polyurethane and polysulphide sealants for expansion joints and dynamic cracks, maintaining waterproof seals while accommodating thermal movement.
Passive Resin Curtains
Installation of passive hydrophilic resin curtains that expand on contact with water, creating permanent waterproof barriers in damp basement walls and retaining structures.
Crack Injection & Sealing Process
Crack Assessment
We inspect cracks to determine type (structural/non-structural), movement (static/active), water presence, and depth. This determines whether epoxy or polyurethane injection is required.
Preparation & Porting
Cracks are routed, cleaned, and injection ports installed at intervals along the crack line. Surfaces are dried (for epoxy) or dampened (for polyurethane) as required.
Resin Injection
Low-viscosity epoxy or expanding polyurethane is pressure-injected through ports, starting from the lowest point. Resin flows through the entire crack until fully saturated.
Curing & Finishing
After curing (2-24 hours depending on resin type), injection ports are removed, surfaces are ground flush, and optional protective coatings applied for a seamless finish.
Frequently Asked Questions
How much does crack injection cost?
Crack injection costs vary based on crack length, depth, accessibility, and resin type required (epoxy or polyurethane). Typical residential basement crack repairs range from £400-£1,200, while commercial structural crack repairs vary based on scale. Contact us for a detailed quote.
What's the difference between epoxy and polyurethane injection?
Epoxy injection creates a rigid structural bond for static cracks in dry conditions, restoring full concrete strength. Polyurethane injection is flexible, expands in water, and works in wet conditions for active leaks and moving cracks. We select the appropriate resin based on your specific crack conditions.
How long does crack injection resin take to cure?
Low-viscosity epoxy resins typically cure within 24-48 hours. Polyurethane resins cure faster (2-6 hours) and react on contact with water. Full structural strength is achieved within 7 days for most crack injection systems.
Can you inject cracks that are actively leaking?
Yes, we use hydrophobic polyurethane resins specifically designed for wet conditions. These resins react with water, expanding to create a permanent waterproof seal even during active leaks. Epoxy injection requires dry conditions.
Is crack injection a permanent repair?
When properly specified and installed, crack injection provides a permanent structural repair. Epoxy-injected cracks are often stronger than the original concrete. The key is correctly diagnosing crack movement and selecting the appropriate resin system (rigid epoxy for static cracks, flexible polyurethane for moving cracks).
