Concrete naturally expands and contracts as temperatures change. Without control joints, this movement causes random cracking. In Calgary’s extreme climate, control joints are essential for directing where cracks occur and preserving the appearance and strength of the slab.
How Control Joints Protect Concrete
Control joints create planned weak points that allow concrete to move without cracking unpredictably. This reduces visible damage and extends the life of the surface.
Where Control Joints Are Used
1. Driveways: To manage vehicle load stress.
2. Sidewalks: To control expansion across long runs.
3. Patios: To maintain clean visual lines.
4. Garage Pads: To prevent structural cracking.
