Concrete Floating Docks
Discover our concrete floating docks — modular, durable, engineered for 50+ year life. Two systems: waler-connected and bolted.
High Performance
Discover the two primary types of concrete floating dock systems: waler connected and bolted. These names refer to the methods used for connecting individual modules, each offering unique advantages for your waterfront needs.
Superior Longevity
Both waler and bolted systems have impressive strength, durability, stability, and load capacity ratings. With proper design and maintenance, concrete docks typically offer a lifespan exceeding 50 years.

Concrete floating docks vs frame floating docks
Concrete floating docks are precast concrete float modules that are connected into piers and fingers and anchored with piles. They sit heavy and low in the water, so they feel stable underfoot, carry high loads and last for decades. As one of the longest-standing concrete floating dock manufacturers, Bellingham Marine builds its modules in company-owned plants in the US and abroad and installs them with its own crews.
Not sure whether concrete or a frame dock is right for your site? This comparison shows the main differences.
| Feature | Concrete floating docks (Unifloat®, Unibolt®) | Frame floating docks (Unideck®) |
|---|---|---|
| Typical service life | 50+ years with proper design and maintenance | 30+ years when well designed and maintained |
| Best suited to | Commercial marinas, exposed sites, superyacht berths and heavy loads | Protected and inland waters (timber and steel), lighter-duty marinas |
| How it is built | Precast concrete modules joined by timber walers (Unifloat®) or bolted together (Unibolt®) | A timber, aluminum or galvanized steel frame carries the deck on separate floats |
| Stability and load | Heavy, stable deck with high load capacity ratings | Lighter structure; capacity depends on frame and float layout |
| Maintenance | Low: durable concrete deck and float in one module | Periodic frame and decking upkeep, especially timber |
