POLYDOCK SECTION SIZES & SPECIFICATIONS

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 below.

Material Specifications:

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.

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.

Deck 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.

Inserts:

Inserts are 3/8” blind brass inserts spaced 1.75”. These are intended for use with 8” poly cleats

Cross Section Detail:

Dock sections have a nominal wall thickness of .25 inches.

Standard Connections:

Connections are designed so that units can be disconnected and moved. Connections are designed to transfer loads applied due to any combination of vertical and horizontal forces.

Venting:

All POLYDOCK sections have a hydrophobic vent plug to eliminate ballooning of the dock.

Anchoring Options:

POLYDOCK has anchoring options for a variety of site specific applications. Check out our anchoring page for more information.
