Foundation underpinning is the process of strengthening and stabilizing a settling foundation of an existing structure. Underpinning is accomplished by extending the foundation in depth or in breadth so it either rests on a more supportive soil stratum or distributes its load across a greater area. Helical Pile Foundation Systems are an alternative to micro piles as a common method in underpinning. Underpinning is also the least invasive of the sinkhole procedures, leaving your home better than when we arrived.

Chemical Grouting

The primary advantage of chemical grouting over a conventional cement slurry grout is its permeation capability in sandy bearing soils. In addition to soil stabilization, chemical grout can also be used as expanding rigid foam to prevent water flow within a soil mass.

• Chemical Grout can be used to help solidify loose materials that were placed prior to construction and were inadequately compacted.

• Chemical grout can also be used to help seal joints or cracks in moving concrete structures.

• Chemical Grout can be used to re-level concrete flatwork that has differentially settled.

• Chemical Grout can also be quite effective when preserving a shear plane in deep excavation applications.

Pressure Grouting

Pressure grouting is a process of injecting a cement grout mixture under pressure (200- 400 PSI) through a series of grout injection points around your home at the direction of the Geotechnical Engineer. Steel casing is drilled into the bedrock, which allows the grout’s application to begin at that depth. As the grout is being pumped in controlled increments, the soils are then compacted, filling any fissures and subsurface voids along the way as the casing is pulled upwards towards the surface.


If you see signs of sinkhole activity around your home or property, call us today and we will inspect your home at no cost or obligation to you. Signs may include cracking on driveways, pool decks, tile, around windows or doors.


PCS is a different type of sinkhole remediation and construction company. We believe that the number one priority is always to make sure our customers are completely satisfied with the work we do, and we do not rest until we make that happen.


What PCS does for residential can also be done for commercial properties as well. We offer a complete line of foundation solutions for the remedial repair of existing structures as well as end bearing deep foundations for new construction applications.


We continously review and refine our systems, processess and procedures in order to deliver a substantial level of excellence to each project. We trust that you will view us not simply as a contrac- tor, but as a genuine partner who is dedicated to provide the services you require to succeed
