GeoTree Solutions is a leading global provider of highly engineered solutions for repairing, rehabilitating, strengthening, and protecting critical infrastructure spanning the water and wastewater, oil and gas, industrial, and civil sectors.

GeoTree’s premium geopolymer solutions and onshore/offshore structural strengthening products can be applied to culverts, sewers, or civil structure repairs. The GeoTree portfolio is unmatched—offering unique, robust, and versatile products for a multitude of applications.


GeoPlug water-stop should be applied when material becomes warm and putty like. Press material into patch area by hand or with trowel and hold until patch becomes hard. To stop in-filtration water, seal crack from top to bottom. Continue this process until the patch area is completely filled with GeoPlug water-stop.

GeoRoc liner creates an integral nano polymeric structure that continues to react over time, resulting in continuous improved performance and strength. This product rapidly cures, which means that the rehabilitated structure can be quickly put back into service after its GeoRoc liner application. GeoRoc liner can also be used in new construction projects as a replacement for OPC as well as high-performance cement mortars.

GeoStrong Repair Mortar is a one-component, non-shrink, fast-setting geopolymer mortar designed for repairing horizontal, vertical and overhead concrete surfaces where high strength is desired.

The GeoSpray® 61 system is designed for multiple application techniques, including pouring, placing, troweling, spraying, and centrifugal casting.

GeoSpray geopolymer is a fiber-reinforced mortar that looks and feels like Portland cement, but with higher performance properties. Unlike other cementitious liners, the unique GeoSpray mortar chemistry provides superior flexural and compressive strength, as well as ultra-low porosity and high self-bonding which eliminates cold joints.

At GeoTree, we solve infrastructure challenges differently. More than just a materials provider, we partner with the industry to deliver smart, practical, innovative solutions. Our breadth of solutions rehabilitate, strengthen and protect infrastructure components.


GeoSpray HCE geopolymer is faster to install than many other repair or rehabilitation products. The result is improved performance and strength with lower total installed costs than alternative methods.

  • A 54” concrete sewer in Bloomington, IL, was beginning to show signs of corrosive deterioration above the flow line of the sewer. They were interested in GeoSpray mortar's capabilities as a geopolymer mortar.

  • Rehabilitating the Lucas County Interceptor Sewer No. 500 was a two-phase project. The most recent phase required a solution that would be impervious to the corrosive influences found in these environments. 

  • A Broward County-owned bridge in Miramar, Florida, which was constructed in 1956 and experienced approximately 1,800 crossings a day, was beginning to show signs of deterioration and structural issues.

  • A bridge in Laurel, Montana needed repairs as the concrete showed signs of distress due to climate and environmental conditions. Read the case study to learn how Geoploymer mortar saved the day.

  • The city of Auburn, NY, approached Precision Trenchless, LLC of Schenectady, NY, looking for a long-term solution to create a new structural penstock within the current structure.

  • Los Angeles Sanitation collects, cleans, and recycles solid and liquid waste generated by residential, commercial and industrial users in the city of Los Angeles and surrounding communities. The system serves over four million residents. The Bureau of Engineering for the Department of Public Works is responsible for maintaining the sewer and stormwater systems owned by the city. Over the last several decades, the city has worked to rehabilitate and replace much of its aging sanitary sewer system. As the progress continues, the city is now doing more work on the larger diameter piping structures in its system. These larger diameter rehabilitations are significantly more costly than the smaller diameter repairs and many of the systems employed by the city are significantly budget constrained.

  • Learn how DC Water utilized GeoSpray geopolymer mortar to repair a brick sewer in the a heavily trafficked business and tourist area.

  • The US Army Corps of Engineers (USACE) is responsible for the maintenance and operation of utilities at Arlington National Cemetery directly on the banks of the Potomac River in Arlington, VA. USACE is currently engaged in a multiyear, multi-phase project to rehabilitate and upgrade the storm water system that handles water and drainage throughout the solemn national landmark.

  • The town of Cary, North Carolina, is an affluent municipality located southwest of Raleigh. The town is near the center of the Triangle region, a commuter area consisting of three major universities: Duke, UNC and NC State as well as the technology hub located in Research Triangle Park. The housing development of Preston is located adjacent to the Prestonwood Country Club, where housing values range between $300,000 and $1M. Bridle Creek Dr. is the main entrance to the community, and the golf course with Bridle Creek crossing though a triplet of 52”-54” CMP culverts. In 2016, a section of one of these culverts collapsed, creating a sinkhole on the side of the road. The collapse was quickly repaired with a new section of CMP, but the community was concerned that the remaining CMP sections were showing corrosion in the invert and it would be only a matter of time before a more serious collapse occurred.

  • During inspections of its road culverts, the city of Rock Springs discovered a corrugated metal culvert that was considered in danger of imminent failure. The 700-foot culvert in question was arched with a maximum height of 48 inches and a maximum width of 72 inches. The invert of the pipe, which was covered with dirt and trash, was mostly corroded away. In fact, approximately 18 inches of the underlying soil had been eroded along the full length of the culvert. In addition to the invert, there were joint separations of more than six inches in many of the joints. The crown had also caved in over a 10-foot section of the structure running directly under the road.

  • Charlotte-Mecklenburg Storm Water Services perform regular inspections on their assets as part of a larger campaign to rehabilitate stormwater infrastructure across the county. When issues are identified the department works to resolve them by including relevant technical experts.

  • When the Lake County Division of Transportation in Illinois identified a metal structure plate arch culvert that showed signs of major deterioration, they needed a way to structurally reline it to ensure it remained in top working condition.

  • When the parking deck of a busy Kentucky hospital was found to have cracks appearing in its slabs and columns the facility’s owners called on design engineers SSE Inc to develop a plan to mitigate the problem. They in turn called on Shield Systems, Inc., a manufacturer’s representative of GeoTree, who had access to a range of partners that could lend their expertise to help create a comprehensive strategy to attack the issue.

  • Engineers from the Louisiana Department of Transportation (LADOT) identified a bridge that required flexural strengthening and repair of spalling concrete on the underside. The busy bridge is raised and lowered around 800 times a month so they needed to find a repair solution which would cause the least disruption to the bridge’s operation as possible.
