What matters
- location, direction, width, depth and development over time;
- loads and construction operations before cracking;
- restraint, joints, temperature and shrinkage effects;
- foundation movement and interaction with adjacent elements;
- strength, serviceability, durability and water-tightness.
Possible responses
Monitoring, sealing or injection, load management, local repair, movement accommodation or strengthening based on the verified cause rather than the appearance alone.
