Abstract
A liquid containment berm and its method of creation, assembly and use, wherein the berm has one or more interior seal members, a floor member and an outer wall member created by applying an expandable foam polymer along a desired retention or flow control pathway, the foam polymer expanding to form the liquid impermeable outer wall member. The berm is assembled and installed on site about a liquid container.
Claims20
A method for containing liquid released from a liquid container having a base configuration, the liquid container being installed on a base surface, the method comprising the steps of:
- positioning a liquid impermeable floor member on the base surface around the liquid container, said floor member having an outer perimeter;
- creating a liquid impermeable interior seal member between the liquid container and the floor member by applying an expandable polymer foam to the liquid container and the floor member, the polymer foam expanding and curing to adhere to the liquid container and said floor member to form said liquid impermeable interior seal member;
- creating a liquid impermeable outer wall member by applying the expandable polymer foam onto said floor member, the polymer foam expanding and curing to form said liquid impermeable outer wall member.
A method for containing liquid released from a liquid container installed on a base surface, the method comprising the steps of:
- positioning a liquid impermeable floor member on the base surface around the liquid container itself or support members for the liquid container, said floor member having an outer perimeter, creating an opening in said floor member, creating a slit in said floor member extending from said outer perimeter to said opening;
- creating a liquid impermeable interior seal member between the liquid container or its support members and the floor member by applying an expandable polymer foam to the liquid container or its support members and the floor member, the polymer foam expanding and curing to adhere to the liquid container or its support members and said floor member to form said liquid impermeable interior seal member, whereby liquid is precluded from entering said opening;
- sealing said slit by applying the expandable polymer foam onto said slit;
- creating a liquid impermeable outer wall member by applying the expandable polymer foam onto said floor member, the polymer foam expanding and curing to form said liquid impermeable outer wall member.
