The leveling compound or mortar can fix small areas of an uneven floor. In fact, this is done regularly for interior floors before installing the floor covering. My solution was to grind the high side down with a diamond blade on an angle grinder until the surface was reasonably level, apply an epoxy filler and cover the floor with an epoxy chip floor that covered any other imperfections. Epoxy is a common way to fill larger cracks, and so is a mixture of polymerized concrete.
The polymer acts as a binder and helps to adhere the filler to the rest of the original concrete on the floor. Organize your garage in one morning. The good news is that most cracks in garage floors are common and are not an indication of serious structural problems, however, there are some that indicate that maintenance is needed or that there may be a structural problem. The concrete contractor intentionally places a cold joint in the concrete when pouring the concrete.
If these sublayers are not well compacted, when concrete is poured onto them, the heavy weight of the concrete will cause these areas to fall a little, and then cracks may occur. Polymerized concrete is cement mixed with special aggregate material that allows it to adhere to existing concrete. Before you get too upset about these uneven areas of your floor, the first thing you should know is that garage floors are rarely level or flat. After you have repaired all the cracks in the concrete, consider adding an epoxy layer to the garage floor.
You will also see problems if the concrete mix contained too much water, too little mortar, was forced to dry too quickly or too slowly. “Concrete Coater” is a cement-based coating that forms a smooth, new surface right on top of old concrete. If a structural contractor drives a piece of heavy equipment loaded with wood on a 4-inch thick concrete slab, it can crack green (not fully cured) concrete. From a technical point of view, concrete needs some curing time before something heavy can be placed on it; concrete must reach a certain strength before heavy wood and equipment reach concrete.
Push the squeegee forward under moderate pressure to drive the respaver into the concrete and force it into the pores and pits. Although the words “concrete” and “cement” are used interchangeably, concrete is really a mixture of cement and aggregate materials such as sand and rocks. You may first notice that the floor of your garage is uneven when something starts rolling a tennis ball, baseball bat, or toy with wheels for children. Depending on the type of concrete, it usually takes 5 or 10 days and even up to 4 weeks before heavy equipment and loads can reach a concrete slab safely; most concrete reaches full strength in about 28 days.
The extension of the respaver without problems is the most complicated part of the project, so it is useful to have some experience with finishing concrete or drywall. Before pouring a concrete slab, it is important to prepare what is often called a subgrade, which usually involves compacting the subgrade and the base (i.
