Abstract
A portable berm for use in and out of doors. The berm includes a impervious flexible synthetic floor which has a berm wall formed about its periphery. The berm wall comprises a plurality of elongated plastic strips which are attached to the floor along their inner and outer edges each forming a cavity which extend around the floor. A plurality of openings are formed in the strips adjacent at least their edges. An adsorbent and absorbent hydrophobic material which allows water to pass through but absorbs chemical contaminants is positioned within the cavities to extend about the floor.
Claims22
A portable berm operative to capture hydrocarbons while allowing water to escape including:
- a flexible impervious synthetic flooring having a plurality of sides;
- a berm wall disposed along each side of said flooring, said berm wall comprising an elongated strip secured along each side of said flooring forming channels, said strips each having first and second ends and inner and outer edges with inner corners of said first and second ends being arranged in juxtaposed positions;
- a plurality of holes arranged at least adjacent said inner and outer edges, said holes being positioned to allow fluid accumulated on said flooring to pass there through;
- hydrophobic absorbent material disposed within said cavities and arranged to extend in continuous contact around said flooring;
- whereby,
- hydrocarbons spilled on said flooring will pass through said inner holes into said cavities to be absorbed by said hydrophobic absorbent material while water spilled on said flooring will pass through said inner holes into said cavities and out said outer holes and away from said cavities and said berm.
A portable berm for use in and out of doors comprising:
- a continuous flexible, non-porous synthetic flooring member having four sides;
- a berm wall formed of a plurality of elongated strips of open mesh fabric with a synthetic coating positioned along each said floor side, said strips having inner and outer edges arranged in laterally spaced positions and attached to said flooring forming channels, said inner edges of said strips being permanently attached with said flooring;
- at least one sock filled with adsorbent and absorbent material positioned within said channels wherein said adsorbent and absorbent material encases said flooring;
- openings of said open mesh fabric being arranged in and along at least said inner edges of said strips, said openings being located to merge with said flooring along said attachment;
- whereby,
- fluid deposited within said berm may pass through said openings and into said channels and engagement with said absorbent sock.
