We provide polyurethane for concrete lifting, compaction grouting for lifting of heavy structures and spray lining solutions for underground structures for Public Works as well as annual maintenance agreements which save government agencies time and money. Whether removing birdbaths on the streets, performing infrastructure rehab, correcting bridge approaches and departure slabs, or filling a sink hole, Superior Grouting has the solution.

Geotechnical Engineering and Application Expertise

Serving Texas and the surrounding states for more than 35 years - Superior Grouting is a specialty grouting contractor with capabilities including cellular grouting, slurry grouting, compaction grouting, chemical grouting as well as polyurethane grouting for the railroad industry.  Our goal is to provide skilled technical expertise and customized innovative solutions to meet the most complex geotechnical engineering challenges. We aim to provide innovative and efficient solutions for all your specialty grouting needs. We have earned the reputation as the “go-to” for demanding applications where safety, quality, responsiveness, and reliability are an absolute necessity.

Public Works

With more than 4.1 million miles of streets and highways, 19 million miles of underground utility lines and more than 16,000 wastewater treatment plants across America, ongoing maintenance is a critical necessity to ensure below-grade stability and above-surface safety are sustained. Superior Grouting works with Federal, State and Local government agencies to provide geotechnical and remedial grouting  services, including Polyurethane and Pressure Grouting. Our pavement lifting, trenchless infrastructure and culvert rehabilitation services are ideal for public works managers, engineers, municipalities and state agencies. We minimize downtime, maximize budgets, and extend the infrastructure lifecycle with innovative no-dig solutions.

High Density Polyurethane Grouting

Polyurethane Grouting is a state-of-the-art approach to repairing sinking concrete. PolyLift™ takes the original concept of mudjacking and combines it with modern knowledge and technology. Rather than using a mixture of portland cement and topsoil, this method utilizes high density polymers to raise slabs back to a desired level. This technique consists of drilling small holes (smaller than a dime) in the slab and then injecting structural grade polymers into the void using specially designed equipment.  After the void is filled, the expansion of the polyurethane allows for a precise lift and stabilizes the slab. 

Common Uses for High Density Polyurethane Grouting

Typical uses for High Density Polyurethane Grouting include:

Eliminate “birdbaths” on streets

Lift/re-level concrete slabs and structures

Infrastructure Rehabilitation

Culvert Rehabilitation

Stabilize Soils

Form watertight seals around manholes and sewers

Waterproofing underground structures

Stop gushing leaks in underground structures

Target Grout Injection (TGI)

Compaction Grouting

Compaction grouting is a specialized technique for in-situ densification of compactable soft or loose soils. A stiff grout is extruded into a soil mass to form an expanding bulb. Any soil capable of being mechanically compacted can be densified by compaction grouting. Superior Grouting’s equipment, capable of achieving grouting pressures of 1000+ psi, can be operated at distances several hundred feet from the injection site and has the capability of drilling in low overhead tight access work areas.

Compaction Grouting Applications

Compaction grouting is versatile; it lifts, levels, stabilizes, supports, fills, and densifies soil for new construction and existing structures and also reduces machinery vibration.  Typical applications include:

Building Sites - Site improvement for structural support and prevention of soil liquefaction

Buildings & Structures - Settlement mitigation, foundation stabilization, controlled lifting

Machinery Pads - Controlled lifting and leveling, stabilization, vibration reduction

Tunneling - Surface settlement prevention, heading stabilization

Drilled Piers - Increased end bearing, lifting of settled piers, skin friction development

Pipelines - Lifting to grade without excavation, restoration of deformed pipes

Tiebacks - Anchor development

Foundation Soil Densification and Strengthening

Compaction grouting can provide an answer to the problem of differential settlement of structures. The versatility of the technique makes it the method of choice for soil densification in areas where access to the site with heavy equipment is difficult or where noise is a problem. Grout injection points can be angled to reach areas under a foundation that otherwise could not be reached.

Controlled Lifting

Compaction grouting is also used effectively for the controlled lifting of foundations, slabs, and other structures. Lifting takes place when the pressure at the bulb exceeds the weight of overburden, structures, and the shear strength of the soil cone above it. At that point, the soil shears, and the grout pressure lifts the soil and the structure built upon it. By the careful use of this technique, entire structures can be lifted and leveled to precise specifications. Unlike other lifting or supporting techniques, compaction grouting supports structures and appurtenances on sound soil foundations.

Void Fill Pressure Grouting

Using the Void Filling Grouting process, grout is pumped under pressure into a void beneath a structure. The cavity might have been caused by a water supply or drainage line break where the adjacent soils have been washed away. The service of void filling and/or soil stabilization is often viewed as a preventive treatment. Concrete areas that feel/sound hollow, 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 with a calibrated cement grout.

There are many variables to consider such as: diameter of pipe, volume of material required, size of annular/annulus space, degree of inclination, size of staging area for grouting equipment and a number of other factors. Typically, Superior Grouting pumps distances ranging from 100 Lineal Feet to 2,000 Lineal Feet. In some specific applications, we have pumped material over a distance of 5,000 LF (~1 Mile).

There are a number of considerations. One critical factor is there is a limited amount of time to place the material required for any given distance. The number of access points is determined by the diameter of the pipe, length and volume of material.

No – the general contractor prepares the pipe for the grouting procedure by installing the injection/vent pipes, the grout plug and any other requirement necessary for the pressure grouting procedure.
