Excavation and removal of abandoned underground pipelines can be extremely expensive but abandoned pipes often cannot simply be left as is. In fact, in certain cases the law now requires that any abandoned pipe be removed or adequately grouted so that it will not collapse in the future and create voids that could cause settlement of the ground surface, roadways or overlying structure.
Installation of injection / vent pipes
Determine optimum mix design and equipment for scope of work
Migration of groundwater and hazardous fluids into the pipe
Build-up of explosive gases in the pipe
Collapse of the pipe, leading to settlement of the overlaying structures
Oil and Gas pipelines deteriorate when they exceed manufacturers’ life of design expectancy. Once pipes are no longer structurally sound, this causes migration of groundwater and hazardous fluids into pipes which can result in a number of is sues, including: pipeline collapse; settlement of the ground surface, roadway structures and overlying structures; soil contamination; and environmental issues.
If not proactively maintained, pipelines deteriorate and/or fail over time allowing soils to infiltrate breached pipes, creating voids around pipes, resulting in ground surface settlement and differential movement to structures above, such as roadways, highways, buildings and other heavy structures.
If not proactively maintained, pipelines are at risk of collapsing, resulting in migration of groundwater and hazardous fluids into and outside of the pipe potentially causing environment challenges, build-up of explosive gases and settlement of overlaying structures.
Our Pipeline Abandonment Grouting (Pressure Grouting) takes place via injecting specially formulated cement-based mixes under low pressures to abandon lines, grout annular/annulus spaces and fill voids beneath structures. Whether the mix design specifications call for a Cellular Grout or Sanded Grout, Superior Grouting will find the best pipeline abandonment procedure for the project requirements.
Abandonment of Underground Pipes
Grouting of Annular Spaces within Electrical Duct Banks
Culvert Rehabilitation
Street Lifting & Leveling
Void Fills.
Fast
Effective
Non-Invasive
Zero Excavation
Environmentally Safe
Compared to heavier grouts, cellular concrete is lightweight and highly fluid, resulting in the following advantages:
Ability to pump for long distances
Minimal shrinkage
Virtually eliminates risk of incomplete filling or plugging of void spaces.
Low hydrostatic and buoyant forces acting on carrier pipes
Extremely flowable and pumpable
Stability and strength with only minimal weight
Lower pumping pressures which reduces the risk of damage to pipe or structure
Requires fewer access points due to the fact it can be pumped over 5,000 feet – fewer access points mean lower costs
Load reduction (vertical and lateral)
Minimizes future settlement
Pressure Grouting is the generic name applied to a number of applications requiring the pumping and injection of any number of variable grout mixtures. When a heavier, higher strength grout is required the use of sanded grout in a variety of mix designs can be utilized.

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. Coming from the concrete boom pumping industry in the 70’s and early 80’s, the owner had extensive experience in the concrete pumping world. Having placed over one million cubic yards in the Houston market he saw a segment in the industry that needed a specialty contractor with the knowledge and expertise to execute conventional and non-conventional projects, thus Superior was born. Starting with one MaycoC30 small line grout pump and a 1969 Chevy Truck, the owner sold and completed each and every job. Superior is a performance-oriented company that works with engineering firms and general contractors and continues to evolve into becoming the exceptional specialty grouting company that it is today. The owner, Ron Rumpza, has diligently worked to grow the company through his persistence and dedication by providing excellent customer service with a quality finished product on time and on budget. The broad experiences of our principle employees combined with unique construction methods and materials, has made Superior an authority in the fields of pressure grouting, compaction grouting, chemical grouting and polyurethane.
The foundation of Superior Grouting’s success is forged around building trust with our customers, employees and suppliers. We are committed to being trustworthy to our stakeholders and earning the right to grow by being reliable, honest, competent and compassionate. This commitment is reflected in how we conduct business everyday as outlined in our core values – wherein Superior Grouting conducts business with all stakeholders, infusing the highest standards of:
Ethics
Integrity
Honesty
Safety-First
Commitment
Accountability
Our Vision is to be the premier provider of Geo-technical Compaction, Polyurethane and Pressure Grouting Solutions for Soil Stabilization and Concrete Lifting Applications serving the Oil & Gas Pipeline, Underground Utility, Railroad, Public Works and Commercial-Industrial Property Management Sectors Serving Texas and the Surrounding States. We are committed to Providing the Highest Quality Remedial Grouting Services in the Safest, Most Reliable and Responsive Manner to Maximum Customers’ Economics.
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.
