Stationary docks include not only residential boat docks, but also multi-slip docks, boardwalks, and piers. These docks do not float; therefore, they are unaffected by wave action. Williamson Boat Docks, Inc. uses hydraulic and pneumatic equipment designed specifically to drive pilings into the lake bed. The pile driving equipment allows stationary boat docks to be built year-round, not just when the lake is lowered. This is one feature that sets Williamson Boat Docks, Inc. apart from most other dock companies.
