Abstract: System for preventing the leakage of liquid from an outdoor work-site around the perimeter of the work-site includes a load-supporting surface having at least two adjacent mats and a plurality of berm members configured to be disposed around the perimeter of the load-supporting surface.
Abstract: System for electrically grounding a reusable load-supporting surface includes at least two mats and a plurality of substantially planar, removable, electrically-conductive covers. Each cover extends at least partially across the top face of one of the mats without extending over any of the edges thereof and is flexibly coupled to the mat sufficient to allow the mat to flex, expand and contract relative to the cover due to environmental factors and the movement of personnel, vehicles and/or equipment across the load-supporting surface during normal, typical or expected use conditions.

Abstract: Methods of manufacturing a plurality of mats useful with a plurality of frame style seal members in a load-supporting surface include at least one milling machine, router or pre-formed mold forming at least first and second elongated grooves in first and second offset outer edges of at least a first side of each among at least first and second stepped-configuration, reversible mats. Each groove causes the seal member(s) seated therein to extend into a gap formed between the mats, abut at least one seal member extending from another mat into the same gap and form a liquid-tight seal therewith.

Abstract: Method of sealing the gap between adjacent mats in a reusable load-supporting surface includes placing an elongated closed-cell compressible sponge rubber seal member along the edge of the first side of a first mat. The third side of a second mat is positioned adjacent to the first side of the first mat, wherein the main body of the seal member is sandwiched between the respective aligned edges of the adjacent mats. At least one locking pin hole of the second mat is aligned over a locking pin hole of the first mat and a locking pin is secured therein.
Abstract: Apparatus for providing illumination from a support surface includes a shell releasably engageable with the support surface. An electronics system is seated within the shell and projects light up and out of the shell. A power pack releasably engages the shell and electrically engages the electronics system to provide power thereto. The electrical interface between the electronics system and power pack is fluidly sealed.

Abstract: An electrically groundable, reusable, load-supporting surface includes a plurality of planar mats and a plurality of removable, electrically-conductive covers. At least one cover is configured to be coupled to each respective mat. Each cover includes at least one mesh portion constructed at least partially of electrically conductive material. The respective covers of adjacent mats in the load-supporting surface are configured to be electrically interconnected. At least one grounding rod is electrically connectable between at least one cover and the earth to electrically ground the load supporting surface.

Abstract: Apparatus for sealing the gap between adjacent interconnecting mats in a reusable load-supporting surface deployed on the ground includes a seal member. The seal member includes an elongated main body and an elongated planar tail extending outwardly therefrom. The main body is positionable in the gap and the tail is configured to extend into at least a portion of the interface formed between upper and lower lips of the adjacent mats.
Abstract: System for assembling a temporary surface includes a grab head and a plurality of mats configured to be placed on the ground and interconnected to form the temporary surface. The grab head includes first and second opposing jaws, each jaw having first and second spaced-apart teeth. Each tooth includes at least one flange and is engageable with one among a series of holes formed in one of the mats.
Abstract: An adjustable locking pin for connecting at least first and second overlapping mats includes an elongated main body, an elastomeric seal extending around the periphery of an enlarged head of the main body and an elongated rotor threadably engaged in a bore of the main body. The rotor is rotatable through at least two 360 degree revolutions of rotation relative to the main body and includes a foot at its bottom end. The rotational adjustability of the rotor allows the first and second mats to be tightly held together.
