Drive-over barrier provides heavy-duty custom containment. Create permanent containment on concrete, asphalt and most sealed areas. Heavy-duty, 40-ounce, vinyl-coated fabric can withstand traffic from trucks, forklifts and other vehicles. Open-cell foam core compresses to approximately 1/4" when driven over and springs back to shape when vehicles pass. Secures to the floor with sealant (not included) and is reinforced with pre-drilled aluminum mounting strips (included) and steel anchors (included). Can be used with standard Ultra-Berm Builder.
