Dock Floats
Benchmark Foam’s dock floats offer a robust and reliable solution for constructing docks and other waterfront structures. These high-quality floats are engineered to withstand the harsh marine environment while providing exceptional durability and buoyancy.
Construction and Design
Dock floats are constructed from expanded polystyrene (EPS) foam, a lightweight yet highly durable material known for its excellent insulation properties. The foam bases are precisely cut to the desired dimensions and fitted with wood furring strips. These firring strips serve as attachment points for decking, allowing you to customize your dock design to your specific needs.
The EPS foam bases are coated with a durable hard coat to ensure long-lasting performance. This hard coat encapsulates the wood and foam, creating a solid, watertight unit resistant to rot, mildew, and other forms of degradation. The hard coat also enhances the floats’ buoyancy, allowing them to support heavy loads without compromising their structural integrity.


Key Features and Benefits
- Buoyancy: EPS dock floats offer excellent floatation to support waterfront structures.
- Durability: The waterproof hard coat shields the floats from the vagaries of the weather.
- Customizable: The firring strips enable you to affix the decking of your choice and other parts on the floats.
- Lightweight: EPS foam is a lightweight material, which makes it easy to work with and transport and also easy to install.
Production Process
The production of EPS dock floats involves several key steps:
- Firring strip insertion: In the EPS foam bases, wood firring strips are provided at a fixed spacing.
- Hardcoat application: A hardcoat is applied to the foam bases, encapsulating the wood and foam into a solid, durable unit.
- Quality control: The finished floats are inspected to ensure that they meet the highest quality standards.
DIY Dock Construction
EPS dock floats are ideal for DIY dock construction projects. With some planning and effort, you can create a custom dock that meets your needs.
To get started, you must determine your dock’s desired size and configuration. Once you have a plan, you can begin attaching decking and other components to the floats.
