Abstract: Shapable protective covers for vertical drains and other holes to prevent spills and other liquids from flowing therein are disclosed. The shapable protective covers include a backing layer with a malleable shapable core and a pliable, tacky sealing layer. The pliable, tacky sealing layer may be secured to the other layers by a bonding layer adhered to or partially embedded in at least one of the layers. The shapable protective covers may be positioned over a vertical drain such that an exposed surface of a pliable, tacky sealing layer contacts a portion of the surface surrounding the vertical drain, thereby preventing liquids from passing through the drain.

Abstract: Berms for use with protective liners are disclosed. The berms may be configured to allow vehicular traffic to pass over the berms without causing damage. Such drive-over berms may be rigid and shaped to allow vehicle tires to pass over them, or may be resilient and collapsible such that they collapse when subjected to the weight of a vehicle tire, and then spring back to shape after the vehicle passes. Also disclosed are berms that may be stacked for storage and transportation purposes, and berms that include connectors for connecting multiple sections of the berms end-to-end.
