Common Types of Concrete Damage

1. Cracks: These can occur due to various reasons, including temperature fluctuations, shrinkage during curing, or excessive loads. Cracks can be superficial or penetrate deeply, affecting the structural integrity.
2. Spalling: This refers to the chipping or flaking of the concrete surface, often caused by freeze-thaw cycles, corrosion of reinforcing steel, or poor concrete mix.
3. Discoloration: Stains and discoloration can result from chemical spills, weathering, or improper sealing, affecting the aesthetic appeal.
4. Scaling: The peeling away of the surface layer of concrete due to freeze-thaw cycles, often exacerbated by the use of de-icing salts.
5. Efflorescence: This white, powdery substance appears on the surface of concrete when water carrying soluble salts migrates to the surface and evaporates.

Concrete Repair Techniques

1. Crack Injection: For narrow cracks, injecting epoxy or polyurethane resin can effectively seal the crack and restore structural integrity.
2. Surface Patching: Applying a fresh layer of concrete or a specialized patching compound to repair spalling or minor surface damage.
3. Reinforcement Corrosion Protection: Treating corroded steel reinforcement with anti-corrosion products and then patching the concrete around it.
4. Overlay and Resurfacing: Applying a new layer of concrete or a polymer-modified overlay to restore the surface and improve durability.
5. Grinding and Polishing: For aesthetic repairs, grinding down the surface and polishing can remove surface imperfections and restore a smooth finish.
6. Sealing and Coating: Applying sealants or protective coatings to prevent water infiltration and protect against future damage.
