1. A system for preventing the leakage of liquid from a reusable load-supporting surface deployed on the ground without the use of any liners beneath the load-supporting surface, the load-supporting surface having at least two interconnected planar mats forming a perimeter thereof, each mat being constructed of impermeable plastic and including a plurality of locking pin holes each configured to accept a releasable locking pin therethrough, the perimeter of the load-supporting surface including at least four sides, at least first and second perimeter sides having an upper lip extending horizontally outwardly therefrom and spaced above the ground, and at least third and fourth perimeter sides having a lower lip extending horizontally outwardly therefrom and resting on the ground, the system comprising:
a plurality of spacers, each said spacer being planar and constructed of impermeable plastic, each said spacer having a first section configured to be positioned on the ground below the upper lip of a portion of at least one among the first and second perimeter sides of the load-supporting surface and a second section extending horizontally outwardly therefrom, each said spacer including a plurality of locking pin holes, at least one of said locking pin holes of each said spacer being configured to be aligned beneath a locking pin hole of an adjacent mat and accept a locking pin therethrough for releasably securing said spacer and the adjacent mat together; a plurality of berm members each having first and second ends, each said berm member being constructed of impermeable plastic and being positionable around the perimeter of the load-supporting surface, each said berm member including at least one horizontal base and at least one vertical wall extending upwardly from said at least one horizontal base, each said berm member being configured so that each said horizontal base is positionable atop and releasably engageable with at least one among the second section of at least one said spacer and at least one lower lip of the third or fourth perimeter sides of the load-supporting surface, each said horizontal base including a plurality of locking pin holes, at least one said locking pin hole of each said horizontal base configured to be aligned over at least one of said plurality of locking pin holes of said spacer upon which said horizontal base rests or the lower lip of the third or fourth perimeter sides upon which said horizontal base rests and accept a locking pin therethrough, each said berm member on the perimeter of the load-supporting surface being configured to prevent the leakage of liquid from the load-supporting surface around its perimeter without the use of any liners beneath the load-supporting surface; and at least one drive-over barrier, each said drive-over barrier configured to be releasably engageable with and between two said berm members on the perimeter of the load-supporting surface, each said drive-over barrier including an elongated, upwardly-angled ramp configured to be positioned atop and releasably engageable with at least one among the second section of at least one said spacer and at least one lower lip of the third or fourth perimeter sides of the load-supporting surface; wherein each said ramp includes a plurality of locking pin holes, at least one said locking pin hole of each said ramp configured to be aligned over at least one locking pin hole of said spacer upon which said ramp rests or the lower lip upon which said ramp rests and accept a locking pin therethrough. |
