Griffin Wellpoint Dewatering System, Jacksonvill, FLA Griffin wellpoint dewatering system in Jacksonville, Florida during the 1950s. The close proximity of the Atlantic Ocean to this excavation, creating a high water table and rapidly recharging aquifer, required a highly efficient dewatering system in order to provide dry working conditions.

This allows Griffin Dewatering to be in total control of the layout, installation, operation, maintenance, removal and abandonment of the designed construction dewatering systems. Because this total concept is a comprehensive approach, it may include an assurance of obtaining specific groundwater control results, depending upon the specific site conditions.

Art C. Little, Senior Estimator for Ron Williams Construction Company, Inc., has worked with Griffin Dewatering on two projects. Little says, “Griffin [Dewatering] performs work in a very safe and professional manner with qualified personnel in a very economical manner.” In fact, Griffin Dewatering was so crucial to the outcome of the projects, that “without [its] expertise and support, the projects would not have been a success for all of the parties that were involved,” says Little.

The same sentiment is echoed by Aaron Buttress, Project Manager for Current Builders. The equipment and services provided by Griffin Dewatering were “essential to [Current Builder’s] ability to perform foundation work,” Buttress says.

“Griffin, as usual, did an excellent job providing the right equipment and maintaining it through the dewatering period,” says Frank Weber, Project Manager for CDC Building, Inc. “We kicked up dust during the entire process of building the foundations and basement, all of which were below NGVD [National Geodetic Vertical Datum].”

Kris Cook, Project Manager for Envirocon, Inc., solicited a bid from Griffin Dewatering. “We were impressed with [its] innovative approach and willingness to help,” states Cook. “[Griffin Dewatering] helped us to develop an approach to dewatering a difficult project.”

The equipment, services, support and technical knowledge provided by Griffin Dewatering are extremely valuable to its clients. In fact, Alejandro Leon, Project Master for Baker Concrete, is quick to point out, after only using Griffin Dewatering on two projects, that Griffin is “critical and crucial to [Baker’s] production.”

Griffin Dewatering Corporation has made a name for itself in the competitive construction market, by offering top-notch service and equipment that is both specialized and tailor-fit to the needs of its clients. It ensures that its clients derive maximum value and benefit from its assistance and support to assure a successful conclusion to any project.
