Concrete is one of the most durable and long lasting floor options for industrial applications, but it can still be susceptible to damage from environmental pressures without proper care. Among these environmental pressures are changes in temperature and humidity, heavy machinery and loads, soil shifting and more. These pressures can lead to cracking if left unchecked, and it’s why expansion joints, construction joints and control joints are so crucial for concrete floors.
As the name suggests, expansion joints are meant to allow for thermal shifts in the concrete flooring. The concrete will naturally shrink and expand depending on the season, and a properly designed concrete slab is supposed to have these shifts absorbed by the expansion joints.
These expansion joints are usually pre-cut and placed in the floor at regular intervals depending on the length and width of the concrete flooring. As a rule of thumb, expansion joints should be spaced no more than 2 to 3 times the thickness of the concrete floor slab.
When properly filled with caulking, expansion joints offer a number of benefits to your concrete floor. They help prevent heaving, which is a movement of the concrete that can cause major structural damage. They also provide a buffer against damage from freeze-thaw cycles. Additionally, they keep water from seeping under the concrete and eroding the soil underneath, which can cause the slab to sink over time.
The best way to protect your concrete floor expansion joints is by regularly maintaining them with a high-quality caulking product like epoxy or polyurea. Epoxy is a popular choice because of its superior durability, seamless bonding and incredible longevity. It is also very cost-effective, and application is quick and simple with a squeegee, pour or trowel.
Using the proper caulking product for concrete floor expansion joints is important because if left open or unfilled, these expansion joints can become a place for dirt, debris and other things to collect in your facility. Additionally, weeds and grass can grow through these unprotected joints and damage your concrete flooring. Using the right caulking products will prevent these problems and extend the life of your concrete floor.
