Crack / Epoxy Injection

/ Highlights

Precision Leak & Crack Sealing

Using industrial-grade resins, we inject deep into the substrate to fill voids completely, providing a permanent seal that is often stronger than the original material.

Restores the original design strength of the cracked concrete element.
Polyurethane injection options completely stop active, high-pressure water leaks.
Monitors and fills the entire depth and matrix of the crack.

/ Benefits

Why Crack Injection Matters

An untreated crack is both a leak path and a stress concentration. Water entering a crack corrodes reinforcement and widens the crack through freeze-thaw cycling, and a cracked section no longer behaves as one piece. Injection addresses both at once with far less demolition than removal and replacement.

Stops water infiltration and interior leaks.
Restores structural continuity in cracked concrete.
Protects embedded reinforcement from corrosion.
Far less invasive than cutting out and re-pouring.

/ Approach

How TNT Approaches Crack Injection

We evaluate whether a crack is dormant or active and whether the objective is structural re-bonding or water sealing, then select the appropriate resin and method. Ports are set along the crack, the surface is sealed, and resin is injected under controlled pressure until the crack is filled full-depth. Where cracking signals a structural cause, TNT coordinates with engineers so the repair addresses the problem, not just the symptom.

/ Signs

When Crack Injection Is the Right Repair

Cracks caused by ongoing structural movement are evaluated first, since injecting a crack that is still moving requires the right resin and, sometimes, addressing the cause.
