Basic Knowledge about Concrete Restoration
- What is Concrete Repair, Restoration?
It is the practice of fixing deteriorated concrete, as well as cleaning and applying a sealant to ensure future protection. If the damage is deep, the concrete will be removed and re-surfaced.
- What causes Concrete Deterioration?
The most common reason for concrete repair and restoration is moisture. Moisture is the most damaging force to concrete. If you have cracked or damaged concrete, it is much easier for water to seep through and this causes further damage to the structure.
