Abstract
Methods of containing liquid introduced onto a support surface include forming the support surface with at least two mats, the mats forming a perimeter of the support surface. A plurality of berm members is positioned at least partially around or proximate to the perimeter of the support surface and extends upwardly relative to the mats sufficient to prevent liquid introduced onto the top of the support surface from leaking off of the support surface around the perimeter thereof.
Claims20
A method of containing liquid introduced onto a support surface, the support surface having a top, the method comprising:
- forming the support surface with at least two mats, the mats forming a perimeter of the support surface, at least a first side of the perimeter including an upper lip extending horizontally outwardly therefrom and having an outer edge, and at least a second side of the perimeter having a lower lip extending horizontally outwardly therefrom;
- positioning a first section of at least one spacer below the upper lip of the first perimeter side of the support surface, each spacer being separate and distinct from the mats and including a second section that extends horizontally outwardly from the first section thereof beyond the outer edge of the associated upper lip;
- positioning a plurality of berm members at least partially around or proximate to the perimeter of the support surface so that at least some of the berm members rest at least partially atop the second section of at least one spacer, at least one of the berm members comprising a drive-over barrier, each berm member extending upwardly relative to the mats sufficient to prevent liquid introduced onto the top of the support surface from leaking off of the support surface around the perimeter thereof;
- and
- positioning at least one drain channel adjacent or proximate to at least one of the mats and between opposing berm members, the at least one drain channel being distinct from the mats and configured to collect liquid introduced onto the top of the support surface.

A method of containing liquid introduced onto a support surface at an outdoor site, the support surface having a length, a width and a top, the method comprising:
- forming the support surface with at least two mats, the mats forming a perimeter of the support surface;
- positioning a plurality of berm members at least partially around or proximate to the perimeter of the support surface and extending upwardly relative to the mats sufficient to prevent liquid introduced onto the top of the support surface from leaking off of the support surface around the perimeter thereof;
- positioning at least one drain channel proximate to at least one of the mats and between opposing berm members, the at least one drain channel being distinct from the mats;
- and
- sealingly engaging each drain channel with any adjacent mats and berm members, each drain channel having an upper surface and at least one liquid passageway recessed relative to the upper surface, each liquid passageway extending at least partially across the length or width of the support surface and being configured to collect liquid introduced onto the top of the support surface.

A method of preventing the leakage of liquid from an outdoor support surface, the method comprising:
- forming the support surface with at least two mats, the mats forming a perimeter of the support surface, at least a first side of the perimeter including an upper lip extending horizontally outwardly therefrom and having an outer edge, and at least a second side of the perimeter having a lower lip extending horizontally outwardly therefrom;
- positioning a first section of at least one spacer below the upper lip of the first perimeter side of the support surface, each spacer being separate and distinct from the mats and including a second section that extends horizontally outwardly from the first section thereof beyond the outer edge of the adjacent upper lip;
- and
- positioning a plurality of berm members at least partially around or proximate to the perimeter of the support surface so that at least some of the berm members rest at least partially atop the second section of the at least one spacer, each berm member extending upwardly relative to the mats sufficient to prevent liquid introduced onto the support surface from leaking off of the support surface around the perimeter thereof.

- and
- sealing engaging at least one of the at least one drive-over barrier with the support surface, each drive-over barrier including front and rear edges and a ramp portion extending therebetween, the ramp portion having upwardly angled faces extending at least partially along the front and rear edges of the drive-over barrier to allow vehicles entering and leaving the support surface to move up, over and down the ramp portion.
