DAM SERVICES

- a wall or barrier that is built across a river or stream in order to stop the water from flowing

and to make a lake.

 

With our deep history of inland dredging, lake and utility services, Harbor Dredge and Dock also provides repair services to Dam structures throughout the state of Virginia. There are only two natural lakes in all of Virginia so every other lake has some type of dam constructed to create the necessary barrier to contain the water. Most Dam's in Virginia are constructed with natural rock and soil some are also constructed using concrete and steel. No matter what type of dam was put in use at our lake, Harbor Dredge and Dock can repair it.

Dredging out the lakes and ponds throughout Virginia, HDD has numerous types and sizes of barges (work platforms, hopper, and sectionals) to help get our talented employees and specialty equipment as close to the repairs as possible. For HDD to accomplish the amazing projects we are hired to constructed wouldn't be completed without the specialty equipment that we own. We have numerous long-reach excavators (60', 54' and 48') that allow us to dredge, hang or reach to certain distances that most excavators couldn't accomplish. Most of the Dams' constructed in Virginia are earthen dams.

 

 

The most common problem that most earthen dams have is tree growth along the top and sides of the berm. In the past it was common to allow the trees to grow on the dam for extra stabilization from the roots of the tree but after numerous powerful storms have blown over those trees by uprooting the ball of the tree creating a weak spot on the Dam. The DCR (Department of Conservation and Recreation) has prohibited trees from being left on a earthen Dam. HDD has a specialty attachment for its excavators known as a FECON Bull Hog. The FECON Bull Hog is a rotary drum mulching head that can mulch a ten inch tree into two inch size piece of wood chips. This device can also grub two to three inches into the soil significantly eliminating the tree chances from regrowing.

HENRICO COUNTY LAKES

Gate Valve Repair and Replacement

The County of Henrico solicited an IFB to rehab three dam structures that are located within a large Commercial Business Complexes. Harbor Dredge and Dock created a cofferdam system with a low flow siphon system to keep the lakes drained so we could repair the concrete, and install new gate valves for each structure.
