Step 1. Prior to the Concrete Lifting process, holes are drilled through the sunken portion of the concrete in a 1.5″ grid pattern. Step 2. A special mixture of grout is then used which is pumped down through the holes and under the sunken portion of the concrete. This grout mixture works to fill in the void which allowed the concrete to sink.
Learn MoreMay 21, 2018 · The holes aren't in every slab, which is why I think it's from slab-jacking, though I have found wood damage in the house (the holes seems more like ant damage). It's actually 3 feet to the property line. Right now the slope is about 1 inch over the 2 feet toward the house, thus I'd want to raise 2 …
Learn More5. Use a hydraulic concrete pump to pump the grout through the core-drill holes. 6. Continue to pump grout into the holes a little at a time until slab starts to rise up. 7. Once the slab is level, cement the concrete-core plugs back into holes. 8. Push the plugs flush with the slab, then use sponge to clean the area around the plugs.
Learn MoreMud pumps (also known as grout pumps, or slab jacking pumps) pump a mixture of water, dirt, and concrete through holes drilled in a concrete slab, filling the voids, and raising the slab until it is level with surrounding slabs. » Check out our HMI Hydraulic Mudjacking Pumps. Material Mixer.
Learn MoreA precise, easy process. Raising concrete with polyurethane foam is done with incremental injections. Lifting foam will fully expand within 10-15 seconds allowing you to monitor the raising and preventing over raising the slab. We suggest using an air-purged gun to deliver foam under the slab. This equipment will keep the injection port open

Learn MoreJun 05, 2021 · Slab jacking. Via Ener Spray. Slab jacking is very similar to the above method, the only difference being the material injected in the ground. The material depends on the type of soil and the type of damage it has caused. Usually, the same mixture as the soil in that region pumps the ground and lofts it up. This process takes some time to cure.

Learn MoreSlab jacking material must be mixed before you place it into the jacking pump. The jacking mix typically contains one part fly ash -- a byproduct derived from burning pulverized coal that improves the ease of pumping concrete -- two parts sand and one part Portland cement.
Learn MoreMud Jacking uses a sand-based material that is generally infused with Portland cement to provide rigidity. This slurry is pumped under the slab to fill voids and raise the concrete. Mud Jacking material will weigh more than the poly product. Polyurethane Concrete Raising injects foam under the slab that swells.
