Concrete lifting, also known as concrete jacking has been around for many years, and is a good way to efficiently repair your concrete without having to pay to replace it. Any amount of concrete can be raised including highway segments, sidewalks, factory or warehouse floors or garages.
You may want to know how it is done?
The technology to lift successfully lift concrete is an old practice. The technology to lift concrete is the same technology used to raise your car on a hydraulic lift at a repair shop. The first step to raise concrete is to drill holes through the concrete, which are about one inch in radius. After a specific mixture of cement, sand, fly ash and water is poured into the holes under high pressure. The mixture then flows beneath the slab and exerts an equal amount of pressure on each square inch of the concrete. The amount of pressure put on the concrete is able to then lift the concrete into place and correct the unevenness that before was a problem.
The amount of pressure put on each slab is somewhere between 50-100 lbs, the concrete itself weighs about .33 a pound per square inch, and thus this is why raising the concrete is a doable task.
So, what caused the concrete to sink?
There are many reasons that cause concrete to sink. Oftentimes, concrete was originally laid on dirt that was not completely packed down. Many times when putting in a new garage floor, driveway or sidewalk, dirt will fall into the trench after the work was complete and therefore was left unnoticed.
