A portable liquid spill containment has a composite base sheet that is formed by spraying a base layer of curable elastomeric polymer compound onto a non-adherent transfer surface. Before the compound cures, a sheet of woven reinforcement fabric is applied to the base layer. An endless tubular containment wall is mounted on the base sheet adjacent its perimeter to isolate a containment area. The containment wall is fabricated of elastic, closed-cell foam which has a memory that enables the material to recover its shape fully after each of repeated deformations. A final top skin layer of the curable elastomeric polymer compound is applied to the base sheet and containment wall to unite them and to develop a liquid-impervious, seamless membrane or cover extending from the containment area up and around the containment wall. In use, the containment is positioned in an area where liquid to be contained is being handled. Wheeled vehicles, such as fuel delivery trucks, may enter the containment area simply by driving over the resiliently deformable containment wall. Any spills are contained within the confines of the containment wall. Prior to the vehicles exiting over the containment wall, the spilled liquid is removed.
