GN specializes in the design and manufacturing of hydrovac slurry processing systems, which are also referred to as slurry dewatering systems or waste slurry management systems. These systems employ liquid and solids separation equipment to effectively treat the soil, soup, or slurry generated from hydrovac or HDD projects. The primary objective is to produce reusable construction materials and discharge clean water by removing contaminants from the slurry.
GN utilizes advanced engineering techniques to develop hydrovac slurry processing systems (Slurry Dewatering Systems) that address the specific requirements of efficient waste slurry management. The system is capable of treating the slurry derived from hydrovac excavation, horizontal directional drilling mud, shield tunnel boring machine slurry, bored piling mud, and other construction slurry waste. By employing liquid and solids separation equipment, such as dewatering vibrating screens, dewatering fine shakers, and dewatering decanter centrifuges, GN effectively separates the different particle sizes present in the slurry. This process results in the recovery of reusable construction materials and the discharge of clean water.

Hydrovac excavation is a non-destructive and precise process that employs pressurized water and a powerful vacuum to simultaneously excavate and evacuate soil. As the pressurized water breaks up the soil, it creates a slurry, which is then extracted into a debris tank using the vacuum system. This non-mechanical excavation method is highly efficient in various soil types, including frozen soil, clay, and hard-packed dirt, as well as in remote or limited-access areas. The waste slurry generated from hydrovac excavation is directed to the hydrovac slurry processing plant, where it undergoes treatment to facilitate water recycling and the recovery of construction materials.
