Pressure Grouting is the generic name applied to several applications requiring the pumping and injection of any number of variable grout mixtures. Pressure Grouting is used primarily by the commercial, industrial, and municipal sectors as a filler for the abandonment of underground pipes, the grouting of annular spaces within underground utility structures and void filling.

Excavation and removal of abandoned underground pipes 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, roadbed or overlaying structure.

Abandonment grouting is the process of filling the pipe with a cellular grout or sanded grout. It is important to remember when pressure grouting to abandon a pipe, it must be done right the first time, since there is not a second chance. Superior Grouting has mastered the art of abandonment grouting with four decades of experience.
Pressure grouting can help reduce several problems caused by the presence of abandoned pipes:
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
Abandonment grouting is an essential technique employed to secure and stabilize decommissioned pipelines, underground utilities, and structures . Utilizing state-of-the-art methodologies, this process ensures the safety and reliability of these areas while offering cost-effective solutions.

In the planning phase of abandonment grouting projects, multiple technical aspects must be considered to achieve the desired outcomes. The key factors are the diameter and length of the pipe that needs to be filled, this dictates the volume and pressures necessary for effective grout placement. Additionally, selecting appropriate grout properties, such as viscosity, density, compressive strength, and set time, tailored to the specific project conditions, ensures long-term stability and effectiveness of the seal.
Dealing with obstacles like fluid migration and incomplete grout coverage is crucial, as they can compromise the seal's integrity. The choice between cementitious or cellular grouts, based on factors such as permeability and soil characteristics, plays a significant role in the project's success. Moreover, implementing advanced grouting techniques and monitoring equipment can enhance the performance and reliability of the grout seal. By meticulously considering these design aspects and overcoming associated obstacles, abandonment grouting projects can be carried out with accuracy and assurance.
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.
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.
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.
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.

“Thank you for a job well done, The attention to detail by Andy and Octavio is praise worthy. Companies build their name based on the quality of their people this is evident. The product performed as indicated, or better than expected, look forward to years of good performance and remaining leveled. To the entire staff, thank you for a job very well done”
“Superior Grouting used injectable foam to fix my cracked concrete. At the same time they lifted various parts of the concrete to even out the surfaces. They were FANTASTIC. On-time, hard-working, clean, precise – everything you want in a contractor. Their pricing was more than fair and their work speaks for itself. I highly recommend anyone using injectable foam for foundations, or lifting any kind of uneven surface to call Ron or Erica at Superior.”
“Great work performed by Andy and Octavio, they stuck around until the work was done it was almost 2200 as they wrapped things up. Professional, courteous and a great attention to detail, most companies build a great name based on the quality of their people and these guys demonstrated it. The product worked amazingly well during installation, it was a dramatic improvement with almost no damage. I am looking forward to seeing how well it will perform in years to come."
