Dock & Marine Construction on Lake Tapps & Lake Washington

Lake Tapps & Lake Washington Waterfront Construction

Lake Tapps is a reservoir in Pierce County with managed water levels that require careful dock design — structures must account for the lake's operating range whether that means a fixed dock with appropriate freeboard, a floating system, or a combination of both. Lake Washington, spanning King and Kitsap counties, is one of the most active boating lakes in the Pacific Northwest, with a dense residential waterfront and strict permitting requirements. Heavy Metal has the experience and equipment to navigate both environments.

Custom Dock Construction

Heavy Metal builds custom docks for Lake Tapps and Lake Washington properties based on the specific conditions at each site — water depth, bottom type, water-level variation, and how the dock will be used. We don't sell a standard kit; we design and build for the site, whether that's a straightforward residential pier on Lake Tapps or a larger multi-slip structure on Lake Washington.

Pile Driving

Fixed docks on both lakes require driven pilings to anchor the structure to the lake bottom. Heavy Metal handles pile driving in-house using purpose-built marine equipment. We bring our own work barge to the site, which allows us to position the pile-driving equipment precisely and work efficiently in the water without depending on land access — on Lake Tapps, Lake Washington, or anywhere in between.

Dock Replacement

Many Lake Tapps and Lake Washington properties have docks that are overdue for replacement. When a dock has reached the point where repair is no longer cost-effective — failing pilings, structural damage, extensive rot — a complete replacement is often the better long-term investment. We can assess your existing dock, explain what we're seeing, and give you an honest recommendation on the right path forward.

In-House Fabrication

HMDM fabricates custom aluminum and steel components in-house, including gangways, structural hardware, and specialty dock components. When your Lake Tapps or Lake Washington property has unusual geometry or conditions that a standard product isn't designed for, we build what the project actually needs.
