Structural Crack Sealing

Cracks are information: some just leak, some still move, some threaten capacity. Injection systems treat each type differently instead of cosmetically hiding all of them.

How the system works

Leaking cracks with active water take fast-reacting polyurethane foams that chase the water and seal it. Dormant structural cracks take low-viscosity epoxy that rebonds the section monolithically. Moving cracks need flexible filling, because rigid injection into a working crack simply relocates it. Diagnosis before injection is the whole discipline.

Common questions

Asked on real sites.

Water is flowing through the crack right now. Can it be sealed?

Yes, that is exactly what water-reactive PU injection is for. Flowing water becomes part of the reaction.

Will epoxy injection restore the structure's strength?

In dormant cracks, properly injected epoxy rebonds the concrete monolithically. If the crack is moving or the cause is ongoing, treat the cause first.

How do I know if my crack is structural?

Width, pattern and location tell the story. Send clear photos with a scale reference on WhatsApp and we will give you a first read before anyone injects anything.
