Void Fill Grouting is typically called for when the roof of a void collapses, or a sinkhole or depression forms producing deformation of the ground surface or when pre-construction site testing uncovers such potential defects. The gradual deterioration of the void, usually over a period of years, most often appears as cone shaped depression, or hole at the surface which can result in damage to buildings, utilities and roads. Damage to structures from void formation may be minimal to severe. These damages may include cracking in foundation walls and floor slabs, cracking of brick veneer, vertical displacement of the structure with severe tilting, an inability to properly open and close doors and windows. Under extreme instances, complete structural failures can occur.
Voids can form under a variety of conditions both natural and man-made. Trash and rubbish buried during construction will produce a void as it decomposes. If the trash pit is located under a concrete slab, building footer or foundation, structural damage will often result from the subsidence. Sanitary and storm sewer pipes breaking will allow fill materials to be carried away producing underground voids.
Water supply or drainage line breaks will cause the adjacent soils to be washed away. Flood plain areas subject to erosion, and poorly compacted soils around foundations, abutments, and retaining walls are just some of the common areas in need of void filling by way of a calibrated cement grout. The service of void filling and/or soil stabilization is often viewed as a preventive treatment.
Void filling grout is pumped under low pressure to fill void under concrete slab. The void might have been caused by a water supply or drainage line break where the soils have been washed away.
Trash and rubbish buried during construction will produce a void as it decomposes. If the trash pit is located under a concrete slab, building footer or foundation, structural damage will often result from the subsidence.
Sanitary and storm sewer lines separating at the joints allows fill materials to infiltrate the utility line producing underground voids.

The service of void filling and/or soil stabilization is often viewed as a preventive treatment.
Filling of the void with a grout is conducted in one of several ways depending upon a variety of factors including location of the water table, the size of the cavity, its proximity to the surface and location in relation to structures. One common and simple technique used to stabilize the subsurface and prevent subsidence is using a sanded cement grout slurry, cellular grout or chemical grout to fill the cavity below. This method employs the use of pneumatic or drilling equipment to install pipes that connect the surface to the void below. The pipes act as conduits to the subsurface void allowing grout to be installed. Grout pipes can be from 1-¼ inches up to 4 inches in diameter, depending on grout mixture and placement volume desired. Once the grout pipe or pipes are in place it is a simple matter to fill the cavity. With the use of shut off valves and pressure gauges it is possible to determine when the cavity has been filled. Once the cavity has been filled the pumps and valves are turned off and the grout allowed to cure.
Superior Grouting determines the size and depth of the void and based on this information, lays out the injection hole pattern, drills the injection holes, determines the void filling grout needed and injects the material into the void under the slab.

Established in 1983, Superior Grouting Services, Inc. is one of the best known and most reliable grouting contractor services in Greater Houston and the Texas Gulf Coast Region. We are a family owned business established in 1983 to provide small line grouting services to general contractors serving the underground utilities, oil & gas, commercial & industrial properties, railroad and public works markets.

Schedule & perform site visit. Evaluate the site conditions. Drill 5/8” diameter investigative holes in affected area. Measure the thickness of the slab and depth of the void at each of the investigative holes and run an average to determine the quantity of void filling grout required.
Superior Grouting uses a variety of materials depending on the size and thickness of the void space and the design/load requirements for the washed-out area. Void Filling Grouts for this purpose range from 50 psi to 2000 psi.
Space requirements vary depending on extent of the void. For your common void fill project, the required equipment space is 50 ft x 50 ft.
Yes – we have a number of different mix designs that range from 50 psi to 100 psi.
Superior Grouting takes great pride in their house keeping. There are two grouting options for void filling, one is with a cementitious grout and the other is a high-density polyurethane. The HD Poly is a cleaner method all in all. Regardless, upon completion of the work, the site is left clean.
