Preparing concrete for repair is a critical step that ensures the longevity and effectiveness of the restoration work. According to Helical Technology, the preparation process typically involves the following steps:
- Surface Cleaning: The process begins with a thorough cleaning of the concrete surface. High-pressure water or pressure washing is used to remove dirt, debris, and other contaminants.
- Surface Profiling: To ensure optimal adhesion and material bonding, the concrete must be profiled to create a rough texture. This is achieved through mechanical methods such as grinding or shot blasting.
- Moisture Prevention: Adjacent areas should be sealed to prevent moisture intrusion during the application of repair materials.
- Site Inspection: A detailed assessment is conducted using tools like crack gauges and soil probes. This helps identify the specific damage and determines if specialized solutions like helical piers or epoxy injections are required.
These preparation measures generally take one to two days to complete and are designed to accommodate Denver’s specific environmental factors, such as dry air and expansive soil conditions.
