Do we need to bolt and glue our berm down?

Definitely glue/seal/caulk your berm down. This creates the seal for the spill berm. Not all surfaces are level, and the glue/sealer/caulk should fill in the holes or gaps on the surface. We also recommend bolting down in place; however, this is up to the customer and your P.E./engineer’s recommendation. If it is in a high traffic area, we highly recommend bolting and sealing/caulking/adhering in place.
