PIG Build-A-Berm Barrier Straight Section can be constructed into a semi-permanent, high-visibility barrier that's exactly the size and shape you need, indoors or out. Pliable open-cell foam barrier springs back into shape after you walk or roll over it with light, wheeled equipment. Durable, 18 oz. all-vinyl covering resists oils, coolants, and most chemicals. Cut to length with a utility knife. For best sealing results, secure to a smooth, sealed surface with Sili-Thane sealant; join seams with industrial-strength vinyl cement. Easy removal requires only a flat-bladed shovel. Great for use around battery charging stations, machinery, or any other leak-prone areas.
