When having a concrete floor installed, one way to prevent cracking and produce longer-lasting results is to have your Plano, Texas concrete contractor install expansion joints and control joints. Expansion joints allow a slab of concrete to expand and contract without coming into contact with any adjacent objects like other slabs or walls. Control joints are used to relieve the stress within a single concrete slab. The joints are designed to control where the crack will occur; so the placement and number of these joints are critical. Discuss different options with your Plano concrete company and figure out the most practical and appealing locations for your joints.
