Many different construction materials are used around the world today, and some date back further than others. Concrete, meanwhile, is nearly universal today, and it is the oldest man-made construction material there is. Primitive examples of it can be found among the ruins of ancient Egypt, made of sand, water, and aggregate, among other ingredients. The same basic idea makes concrete today, though of course, concrete recipes are carefully made and so, today’s concrete is much stronger than anything from antiquity. Concrete is used to make anything from highway overpasses to building foundations to sidewalks and floors, but of course, concrete is not indestructible. Sometimes, experts need to be hired to perform concrete leveling, crack repair, or concrete grinding, all this can keep a building or sidewalk in good shape for years to come. When is it time to call for concrete grinding services, and what exactly do they do? And what about concrete leveling companies?
When to Hire Concrete Leveling Crews
This is mostly a concern for concrete patios for homes and sidewalks of all kinds. These are examples of outdoor concrete usage, and while famously tough, concrete might sometimes suffer from natural effects, such as from sagging earth. A sidewalk is built right on the ground, and sometimes, that earth will get laden with rain water and sink due to its weight, creating depressions. The problem is that concrete sidewalks wills sag right along with it, and this disruption will result in serious cracks, breaks, and uneven levels in the sidewalk’s surface. At the very least, this results in an unsightly sidewalk, and worse yet, this sidewalk is a serious tripping hazard for pedestrians and is disruptive for wheeled vehicles like bicycles and skateboards.
So, local concrete leveling services can be hired, and they use modern materials and techniques to get a sagging sidewalk or backyard patio back in shape. This service will not work for patios that are attached to the house’s foundation, however. What comes next is a simple but effective process: a pump is set up, and it injects a quantity of material under the sagging concrete that rapidly expands and hardens. This material, expanding like balloon, will raise the sagged concrete back to its intended level and keep it there, and the material should not need much time to harden. Once the concrete is lifted back into place, the workers can apply the finishing touches, such as crack repair, using tools to fill up the cracks and seep the material into the concrete with capillary action. Before long, the sidewalk will be smooth, attractive, and ready for use. This compares well to older mudjacking methods, where there was a 24-hour wait period between lifting the concrete and allowing people to walk on it.
Concrete Grinding Done Right
Meanwhile, it should be noted that more and more building are now making use of concrete flooring for their ground floors, which compare favorably to tile or linoleum floors. This applies not only to warehouses and factories, but also banks, schools, and the like. Regular concrete has a strength of 3,000 psi (pounds per square inch), and some of the strongest concrete out there has a strength of 2,000 psi or even more. Polished concrete offers durability and performance that other floor types can’t easily match.
When a new concrete floor is poured during construction, or when an old commercial building is bought, it is time for concrete grinding to be done. Why? Concrete may be tough, but to be used as a floor, it must also be clean, perfectly level, and have epoxy applied to it. Floor treatment can make the concrete floor even tougher and more attractive, help it resist stains, and make it easier to paint on. But grinding is done first, to prep it for epoxy.
Floor grinder machines are pushed by hand, and their rotating disks will grind up the surface and make it perfectly flat and level after enough work (small, handheld models are used on the room’s corners). This can strip off a thin layer from the concrete, and clear off any bumps or other imperfections, and the workers must use hearing protection as well as protect their face from the concrete dust cloud during work.
