Technical Details
Each PolyDock modular floating dock section consists of a polyethylene single cavity, hollow, non-foam-filled float structure that consists of an integrated deck surface and flotation. The deck surface features a herringbone brick pattern, the spaces between each molded brick are no greater than 3/8″ wide and 1/2″ deep and allow for water drainage from the deck surface. Each brick in the herringbone pattern is approximate 4″ x 8″ except where the full brick pattern is not feasible as part of the pattern. Dock sections have a nominal wall thickness of .250 inches. Due to manufacturing tolerances in the rotational molding process, actual weights and dimensions may vary slightly from those listed.
Material Construction
The Polyethylene material shall meet the following properties: 1. 100% Polyethylene. 2. Has an ultraviolet inhibitor (UV-8) to protect from the sun. 3. The Polyethylene has tensile yield strength of 3,410 psi as per ASTM 638. 4. The Polyethylene has a low temperature impact of 160 ft-lbs (foot pounds) as per the ARM test method (Association of Rotational Molding) The ARM test method has been used since 1995 when the ASTM D3029 was made obsolete.
General Features
Surface: The deck surface has a herringbone brick pattern. The gaps between bricks are no greater than 3/8” wide and 1/2” deep. The gaps are provided for water drainage from the deck surface. The bricks are approximately 4” x 8”. The surface also has a 550 shotpeen finish to provide added anti-slip to the deck surface.
Nominal Wall Thickness: .250 inches
Freeboard: Freeboard under dead load shall be 14.50 inches +/- 1”. Freeboard under dead load plus 30 pounds per square foot shall not be less than 8 inches.
Connection: Lightweight aluminum connectors and stainless/brass hardware
Inserts: Inserts are 3/8” blind brass inserts spaced 1.75”. These are intended for use with 8” poly cleats
Venting: All POLYDOCK sections have a hydrophobic vent plug to eliminate ballooning of the dock.
Cross Section Detail: Dock sections have a nominal wall thickness of .25 inches.
Where Other Docks Struggle, PolyDock Excels
Common Dock Issues | With PolyDock |
Slick or hot surfaces | Slip-resistant, cool-to-touch walking surface |

What makes PolyDock different from other dock systems?
PolyDock combines slip resistance, saltwater-ready durability, and modular flexibility with proven reliability in residential, commercial, and municipal settings.
Is PolyDock safe for kids and pets?
Yes. The surface is barefoot-safe, slip-resistant, and stays cool under the sun.
Can PolyDock be used in deep or rocky bottoms?
Absolutely. Anchoring options make it suitable for steep banks, rocky bottoms, and tidal water.
How does it handle winter ice?
In protected bays, docks can remain in place. In harsh conditions with shifting ice, seasonal removal is recommended.
How expandable is the system?
Highly expandable. Start small and add sections or accessories at any time.
