Strengthening the Foundation
At SGS, we understand that preventing water intrusion is critical for the longevity and stability of structures. Grouting is an effective solution to stop water infiltration, especially when traditional waterproofing methods have failed or are not viable.
Our specialized team is experienced with various grouting materials and methods for below-grade and above-grade projects. For significant water intrusion, our experts use a multi-faceted approach, leveraging various grouting processes to achieve long-lasting results. In many cases, grouting has resulted in cost savings for our clients compared to other waterproofing solutions.

Our Grouting (Soils) Services
Soil Stabilization/Compaction Grouting
SGS excels in advanced soil stabilization techniques, like compaction grouting, to ensure your foundation is strong and secure. Using a high-pressure injection of low mobility cementitious grout, our experts displace and compact soil at depths of up to 30 feet below ground level. This precise process forces soil grains into tighter packing, reducing pore volume and creating solid, grout-filled masses that fortify the ground.
By eliminating air and water from the area, we effectively stop water infiltration and ensure a stable foundation, protecting your building from future risks. Trust SGS to deliver industry-leading solutions for lasting ground stability.
Void Filling
Our team is highly experienced in addressing voids that can threaten the stability of buildings, utilities, and roads. Whether caused by natural conditions or human activity—such as decomposing buried materials—voids often lead to dangerous ground surface depressions, sinkholes, and structural damage. These issues can result in cracked foundation walls, floor slabs, and brick veneers.
Our void filling solutions are tailored to each unique situation, considering factors like cavity size, proximity to the surface, water table location, and nearby structures. Whatever the situation, you can count on SGS to restore stability and prevent further damage, ensuring your property is protected from future risks.
Sinkhole Remediation
SGS delivers tailored, reliable solutions to safeguard your property from the potentially devastating impacts of sinkholes. One of our proven methods involves injecting polyurethane foam deep into the soil to compact and stabilize the affected area. This effective technique, often combined with our expert compaction grouting services, helps restore ground integrity and prevent further damage.
Curtain Grouting/Permeation Grouting
Curtain grouting is a durable waterproofing solution for underground structures, including tunnels, parking garages, and basements. Our expert team uses a precise grid pattern to drill holes and inject chemical-based grout, forming a protective "curtain wall" that permanently seals out water.
This method is particularly effective for stopping active water leaks when excavation isn't feasible due to nearby roads, sidewalks, or shared alleyways. Often part of a multi-pronged approach, curtain grouting is an ideal solution for preventing significant water intrusion and ensuring the long-term protection of your property.
Slab Jacking
Our slab jacking services provide an efficient and cost-effective solution for stabilizing uneven or sinking concrete surfaces. Whether a sidewalk, plaza deck, or garage floor, our experts drill precise holes through the concrete and inject grout to fill any voids beneath, raising the slab back to its original level.
This method is perfect for addressing trip hazards, sunken pavers, and cracked concrete without the need for costly replacement. Slab jacking not only restores structural integrity but also extends the lifespan of your concrete surfaces.
