Concrete repair involves fixing damaged or deteriorated concrete surfaces to restore their strength and appearance. Common issues include cracks, spalling, and surface wear, which can occur due to weather, heavy loads, or improper installation. Repair methods may include patching, resurfacing, or using specialized materials like epoxy or polyurethane. The repair process typically starts with assessing the damage and cleaning the affected area. After preparation, appropriate repair materials are applied to fill cracks or restore the surface. Proper curing and sealing are essential to ensure the longevity of the repair, helping to protect the concrete from future damage.
