U.S. Aqua Services provides top notch and innovatively designed dredging equipment that can be rented. This internal pile excavator safely and quickly removes material from inside of the pile or caisson, allowing for internal cuts to be utilized. Our dredging company offers both a jetting excavation system and a mechanical excavation system. The jetting system utilizes a Venturi type dredge, while the mechanical system utilizes a combination of hydraulic dredge and a mechanical excavator. Custom designed and manufactured in-house at U.S. Aqua Services, both systems feature an outer diameter of 29½” and come complete with hydraulic power systems, reels, and all equipment needed for operation.
