Stronghold Berm is a simple but effective berming system designed specifically for holding containment in place. Constructed from recycled rubber, it’s the most environmentally friendly berming solution available. It uses a “lock and key” design which eliminates the need for fasteners, like nails and screws, which are commonly dropped on site and are a detriment to equipment. Our berm improves upon the quality of containment and structural integrity to hold liquids and creates a safer working environment for employees. Caution Yellow tops clearly define the site perimeter. Ramps specifically designed for this system allow even the largest vehicles to safely navigate over the berm.
