Inflow and Infiltration Trenchless Repair
This new video highlights three projects where the URETEK polymer injection process is used to trenchlessly seal and repair lateral lines and manholes from inflow and infiltration (I/I). The application is quick and cost-effective and provides effective I/I mitigation.
Ground Works Featured in Trenchless Technology Article
In the July 2016 issue of Trenchless Technology, Ground Works Solutions’ CFO, Aaron Hall, writes about the successful rehabilitation of a box culvert in Pensacola, Florida. In the piece, Aaron discusses the problems created by historic flooding in Escambia County and how Ground Works Solutions was able to lift a box culvert structure by two feet in order to restore its long-term viability.
You can read about the scope of the project and the challenges in the article here.
Great Sinkholes Documentary – Buried Alive
In a recent PBS sinkholes documentary produced for the NOVA series, Sinkholes – Buried Alive, viewers learn about the geology that sets the stage for sinkholes across the globe, including karsts, limestone, gypsum, rock layers, salt domes and sandy soil.
The documentary also covers the warning signs for sinkholes and some of the experiments that geologists are conducting to understand how fast a sinkhole can occur, as well as the devastating effects of a massive storm dumping water onto the earth’s surface after water has been pulled from an aquifer for irrigation.
Most important, viewers learn about the different technologies and applications to detect and protect people and property from emerging sinkholes, including ground penetrating radar (GPR), soil testing, and different methods of soil stabilization.
Rehabilitating Soils to Increase the Bearing Capacity Under Milk Storage and Grain Handling Facilities
Silos are storage systems designed to contain massive amounts of weight within a concentrated area and vary in size, ranging from 20-80 feet tall with diameters of 12-30 feet. Some storage facilities have more than one or two silos sitting in a small area. When the silos are full, the significant weight can impact settlement of the foundation and/or the foundations of nearby structures.
In addition to the consolidated weight of tanks that hold liquid and grain storage bins, the surrounding processing facilities get a lot of traffic as well. There is a constant stream of trucks, mostly loaded with heavy cargo, coming and going from the facility. When there is a rail spur next to the facility, the soils underneath and around the grain bins, silos, and mission critical buildings are taxed with even more weight. Consequently, there is a lot of weight consolidated into a relatively small area around these crucial, very busy facilities.
After heavy rainfall like…
Soil Stabilization under 100-Year-Old FDNY Firehouse
Fire stations are critical in serving the diverse needs of the community where they are located, as well as the fire department they report to. The New York City Fire Department (FDNY) protects more than 8,000,000 New York City residents living and working in a 320 square mile radius. The FDNY is the largest fire department in the United States.
The FDNY serves the five boroughs of New York City and includes 255 fire stations. Each fire station’s differences relate to the size of the firefighting apparatus housed within it and the facility’s location, which is largely driven by the need to minimize response time. The FDNY Engine Companies are tasked with securing a water supply and extinguishing the fire while the FDNY Ladder Companies conduct search and rescue, forcible entry, and ventilation at the scene of a fire.
