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…
Zero Excavation Inflow & Infiltration Restoration At the Naval Air Station in Pensacola after a High Water Event
Ever since the U.S. purchased Florida from Spain in 1821, the site where the Naval Air Station (NAS) in Pensacola currently stands has provided a base for military operations. In 1826, construction began on the Pensacola Navy Yard and it eventually became one of the “best-equipped naval stations” in the U.S. During this period, the Navy Yard was used for docking and repairing the warships of that period. When the Navy saw the advantages of aviation in combat, Pensacola became an aviation training station in 1914 and the station was built on the side of the old Navy Yard. In 2014, NAS Whiting Field celebrated 71 years in operation and is considered to be the “backbone of the Navy’s flight program” and is still one of the most important Navy bases in the U.S.
Foundation Damage Caused By Melting Snow and Ice
The winter of 2015 will go down in the history books as one of the snowiest. In fact, as of March 15, 2015, Boston had accumulated a total of 108.6 inches of snow. This was the most amount of snowfall since the city started tracking weather back in 1872. It has also been a brutally cold winter across the entire Northeast. Once again, Boston broke records, averaging only 16.1 degrees in February.
After a long season of shoveling, snow blowing and digging out the car in order to go anywhere, warmer weather is a welcome signal that spring is almost here. Experts predict that this spring’s runoff from melting snow and ice will be the worst we’ve had in the last 15 years. Unfortunately, melting snow and ice can cause damage to houses and other buildings and may uncover some unwelcome cracks in the foundation. As a…
