Most contractors have been taught to use concrete leveling tools as a means of leveling concrete surfaces. But is this approach appropriate in all situations? Most contractors do not realize that they are using a concrete leveling tool. Other tools include Trowels, Erector, Alligator Grinding Device, and Backhoe.
Concrete leveling methods involve spreading a concrete-like material (sometimes referred to as grout) across a surface to remove the top layer of soil. The objective is to lay down a smooth and level surface where there was previously a crater. It is the first step in the process of reducing water and earth from an area. This is done by injecting a material into the hole which deposits a pile of debris in its place. Also, gravel and dirt can be introduced into the hole to support the material being injected.
There are two types of concrete levelers. Grout grouting machines, such as wall grouts and some fence grouts, create small holes in the surface to inject grout. Mudjacking is a similar process where the homeowner uses coarse grit, or sand, to fill in the hole. Mudjacking is often used on sidewalks, driveways, and other hard surfaced areas.
To determine if mudjacking is an appropriate choice for your project, consider the following: If you have a slab above grade, then mudding may be acceptable. However, you should check with your local building codes for regulations on adding soil in areas where the slabs are above grade. Some slabs are only ten inches thick. If the depth of the hole to be filled exceeds this thickness, then this procedure will most likely require a permit.
Mudjacking concrete levelers can be used on porous surfaces such as those found on a parking lot. A dirt forklift can lift and drop the concrete truck-mounted leveler into the hole. As with other types of concrete leveling equipment, mudjacking can be used over a concrete surface and concrete grout can be placed in the hole.
Larger concrete levelers and grinders can be used to fill in some potholes and holes in a driveway. This can be done manually, but it is much easier to use a concrete auger bucket when the hole is more than three feet in diameter. The bucket allows the auger operator to quickly scoop out small rocks or pebbles.
Concrete levelers should be checked periodically for wear and tear. This is especially true if the grout has become saturated. Using a level, can be quite hazardous if it is not maintained properly. In the case of a pool, the stones can collect in the machine and cause a hazard.
It is recommended that concrete levelers are inspected at least once a year. Using a cement grinder is a good way to make sure the concrete truck-mounted leveler is operating properly. The grinding equipment used can also help prevent any damage to the concrete surfaces in a driveway or walkway.
