CONCRETE REPAIR AND CRACK TREATMENT

Cracks, honeycombing, spalling and leaks are all signs that concrete is deteriorating. Treating them early and for the right cause avoids spreading damage and larger repair costs later.

Common problems

• Cracks caused by shrinkage, settlement, loads or temperature changes
• Honeycombed concrete and loss of the protective cover
• Rusting reinforcement that expands and spalls the concrete cover
• Water leaking through cracks, construction joints and pipe penetrations
• Concrete floors that are dusty, worn or flaking at the surface

Treatment solutions

• Crack injection (Epoxy or PU, depending on whether the aim is strengthening or stopping water)
• Removal of weak concrete, treatment of rusted reinforcement and patching with specialist repair mortar (such as PENECRETE MORTAR)
• Stopping active leaks with PENEPLUG fast-setting mortar
• PENETRON crystalline waterproofing to protect the concrete after repair
• Floor surface treatment with hardener, grinding and protective coating

Process

1. Survey: record the location, width and direction of cracks and the condition of the concrete and reinforcement.
2. Identify the cause and propose a method.
3. Prepare the surface, remove weak material and clean.
4. Apply repair materials or inject according to procedure.
5. Finish and add protective waterproofing if needed.
6. Acceptance and follow-up.

For damage affecting load-bearing structure, ANTINCORP recommends an assessment by a structural consultant before work begins.
