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.
