The polymeric coating 16 which encases the core 14 is preferably Docket hfo. 58584.US11458.7 a polyethylene coating. The coa#ing 16 is preferably roughened to facilitate bonding to the concrete 18, and may be abraded or have appendages, corrugations or the like.
The coating I6 inhibits moisture from contacting the core i 4 to avoid the core 14 from becoming wa#erlogged and otherwise deteriorating from exposure to moisture, chemicals, and other substances which tend to deteriorate the core 14.
Tfdesired; a vent may be provided between the Bore I4 and the atmosphere to enable venting of gases that develop. This may be accomplished as by a polymeric tube 27 or the like located to pass from the core and through the coating I6 and concrete 18 to a surface of the concrete, such as a side zteax the top. The exposed end of the tube is preferably I O configured to izahibit passage of moisture or other matter back to the core.
The concrete 18 is preferably a Lightweight, regular weight, or polymer modified concrete material applied so as to surround the core 14. °The corrosion resistant mesh 20 provides reinforcement to strengthen the concrete 18 against loading, environmental changes such as temperature changes, arid fhe like, 'fhe mesh 20 is preferably made of carbon fiber, polymeric zxxaterials such as polyethylene, glass reinforced plastic, or like materials which are substantially resistant to corrosion in a marine environment and resistant to corrosion in azt alkali-concrete environment.

iQ The units 10 are made using a suitable mold and tensioning devices for pouring of the concrete. After the concrete is cured, the fber members 22 are preferably trimmed to be hush with the exterior of tiae concrete 1$ or the post tensioning member 26 ox restraints therefor. An upper or deck surface 28 of the concrete 1$ zxiay-be brushed during curing to provide a non-slip surface 3X.
'U~lith reference to FIGS. 4A-4~, the concrete rz~ay be configured to receive threaded inserts 30 for attachment of mooring cleats 32, with the insert 30 preferably being configured, as by including an aperture, for passage of the pretensioned fiber members 22 or otherreinfarcement. Likewise, rail member 34, such as a board, preferably having a rubber bumper rail 3~ adhered thereto, may be attached ?0 as by bolt 38 which cooperates with the insert 30. The rail member 34 preferably includes an insert portion .39 so that the bait 38 does not protrude. Also, elastozxaeric Docket hlfo. 58584.US11458.7 pads 40 are preferably adhered or otherwise secured to the exteriors ofthe units la for padding between adjacent units.
With reference to FIG. SA, a plurality of the units ,IO are intercor,~~eated and extend from a boarding ramp 4~ which extends from a bulkhead 44. In FIG.
SB, a floating platform 46 is provided by a plurality of the units 10 arractged side-by-side.
In this regard, it is noted that the units 10 may be of a variety of sizes and conitgurations and may be utilized with: other units 10 or ather structures to provide a wide variety of floating configurations.
