How Do You Make Expansion Joints In Concrete Slabs?
Concrete cracks under stress. It can crack under the stress of heat or cold. As it hardens after being poured, it shrinks; this action creates tension, resulting in cracks. How do you keep your concrete from cracking? Use expansion joints. These joints are spaces within the slab that allow for expansion and contraction due to changes in temperature and moisture, and for shrinkage during the curing process. Add expansion joints when you pour your slab. If you’re pouring your slab in several pours, you can install ready-made expansion joints between the pours. Expansion joints are typically made from cork or rubber, but you can use thin slats of wood. Install expansion joints by setting a joint within the framework of each of your pours. A joint is placed between the first pour and the second. The second joint is placed between the second pour and the third, and so on. The joints are left in place. The installation of expansion joints results in the slots you see in sidewalks and drivewa
