Heat causes concrete to expand. Cold causes it to contract. Since concrete is very stiff, if there are weak spot it can crack during expansion and contraction cycles. Expansion caused by heat creates pressure and stress on the concrete. Steel rebar or, for smaller projects, wire mesh grids can help extend the concrete’s life span and reduce the number of future cracks. 6. Keep an Eye on the Weather. The best time to pour concrete is during warm weather. Don’t attempt this job when surface temperatures could drop below 35 degrees Fahrenheit.3. Cracked Concrete Substrate. In many instances, issues start at the bottom. Concrete is a fairly stable substrate for tiling, but only if the concrete itself is healthy and free from cracks. Older concrete slabs can develop long cracks running through them, and over time, they spread to the above tiles in the form of reflective cracks. 1. Plastic shrinkage concrete cracks. When concrete is still in its plastic state (before hardening), it is full of water. When that water eventually leaves the slab, it leaves behind large voids between the solid particles. These empty spaces make the concrete weaker and more prone to cracking. ….
