In civil engineering, concrete raising is a process that attempts to adjust an uneven concrete surface with the help of mechanical equipment. Unlike many similar processes, this one actually tries to make the surface level and free of bumps, cracks, or other imperfections that could affect how well anything is built. The very foundation of the house you are living in may very well be sitting on top of a completely level dirt foundation, but it is still incredibly likely to have some fairly substantial bumps in it. Without some type of levelness adjustment, you might end up with the impression that your house doesn’t even belong on the ground, instead being sitting on a bunch of pebbles. This could be incredibly undesirable, leading to a whole class of home built in the 1930s being torn down due to ground problems. Have a look at Concrete Raising.
One way to avoid this kind of problem is through a method called concrete raising. Essentially, a huge array of slabs (usually ranging from four to eight feet in width) are sunk into the ground beneath your house and then set up on top of a specially designed raising platform. When raised to the proper level, the raised concrete slabs can be guided slowly into the area where they are needed and then covered with protective plastic. Once the concrete is set in place, a series of hydraulic pistons will shoot the concrete upwards, effectively leveling out the area once and for all. While it sounds like an incredibly involved process, most experts estimate that it takes around four hours of work to level a level basement or garage.
Another way of avoiding grounding problems and leveling problems is through the employment of another method called mudjacking. As the name suggests, this process involves the use of a large pail of water to pump out excess water from beneath the ground. Afterward, the water is pumped back in, filling the hole left by the mudjacking concrete slabs. This is often times a very expensive and time-consuming process, but it can level an entire floor quickly if you are only repairing a few areas. Additionally, it can make cleaning after the mudjacking easier because it drains away the water and mud that would have otherwise gotten tracked throughout your house. Given the numerous ways that concrete can be used to make your home more safe and efficient, it’s likely that you will never run into any ground problems that cannot be easily cleared up with concrete raising.
