Expansion Joint Filler – You’ll notice in almost all garages there are joints that typically break up the garage into 4 squares or more. Some customers opt to have them filled for 3 reasons. For one, its just a beautiful look. Secondly, it’s one less area you have to clean dirt and debris out of. Thirdly, for those who are rolling anything across the garage floor with smaller wheels, those wheels tend to get caught in the joint, and in some cases, break the wheel off. Something as basic as a garage shop vacuum is a great example. As you pull the vacuum across the floor, the wheels will get jammed up in the joint, and the vacuum will fall over or break the plastic wheels. A VERY IMPORTANT NOTE on filling expansion joints. In most cases the joints are filled incorrectly, even by contractors who mean well. The most common materiel used, is concrete or a concrete based patching compound. This is the WORST product to use. It will 100% crack, and ultimately fail in just a matter of months. Expansion joints move from thermal expansion and contraction, therefore a very specialized material must be used. A product designed specifically for “moving joints” that is both rigid like concrete, but flexible enough to move with the joint. The joint itself must also be scored and prepped properly before being filled. We are certified by both Sika & Metzger McGuire on proper expansion joint fillers.
