You can do a few things during the construction process to minimize the chance of cracking. First, starting with a sound, compact subgrade is essential, and modifying your concrete mix with a lower water-to-cement ratio can also help. Being purposeful with your control joint placement and properly curing your concrete can also reduce the chances of cracking. One last thing to remember is that pouring concrete on frozen ground can often lead to cracking. As long as your crew is mindful of the above items, you should end up with a sound concrete job.
