Why Concrete Cracks and Repairs Often Fail
Concrete deterioration and cracking often occur when moisture reaches reinforcing steel, causing corrosion and expansion within the concrete.
Concrete repairs often fail when the underlying causes of deterioration are not properly addressed.
Long-lasting concrete repairs require correct preparation, engineered repair materials and experienced installation.
That’s where a concrete repair specialist makes the difference.
Proper concrete repairs usually involve:
- Identifying the cause of concrete deterioration
- Removing unsound concrete
- Treating reinforcement where required
- Installing engineered repair systems
- Delivering repairs in controlled stages
