A method includes placing at least one mold along outer edges of one or more first pieces of fabric. The method also includes forming free-standing flexible walls and a floor of a containment structure by depositing liquid-impervious material onto the at least one mold and the one or more first pieces of fabric. The floor is formed seamlessly with the walls. The method further includes forming flexible supports by depositing liquid-impervious material onto multiple second pieces of fabric connecting the floor and the flexible walls.

1. A method comprising: placing at least one mold along outer edges of one or more first pieces of fabric;forming free-standing flexible walls and a floor of a containment structure by depositing liquid-impervious material onto the at least one mold and the one or more first pieces of fabric, the floor formed seamlessly with the walls; andforming flexible supports connecting the floor and the flexible walls, wherein each flexible support is formed by depositing liquid-impervious material onto one or more second pieces of fabric having a first end connected to the floor and a second end connected to an inner surface of one of the walls such that the one or more second pieces of fabric are positioned entirely within a space between the walls and above the floor. 2. The method of claim 1, wherein: forming the flexible walls of the containment structure comprises depositing liquid-impervious material onto the at least one mold; andforming the floor of the containment structure comprises depositing liquid-impervious material onto the one or more first pieces of fabric. 3. The method of claim 1, wherein: forming the floor of the containment structure comprises depositing liquid-impervious material onto a first side of the one or more first pieces of fabric; andthe method further comprises depositing liquid-impervious material onto a second side of the one or more first pieces of fabric to protect an underside of the containment structure. 4. The method of claim 1, wherein the free-standing flexible walls are configured to be repeatedly depressed and to return substantially to their pre-depressed shape. 5. The method of claim 1, further comprising: rolling up the containment structure without removing any portion of the free-standing flexible walls and any portion of the flexible supports. 6. The method of claim 1, wherein the first and second pieces of fabric comprise felt. 7. The method of claim 1, wherein the liquid-impervious material comprises polyurea. 8. The method of claim 1, wherein placing the at least one mold along the outer edges of the one or more first pieces of fabric comprises: placing the outer edges of the one or more first pieces of fabric on portions of at least one L-shaped mold. 9. The method of claim 1, further comprising: applying a releasing agent to the at least one mold prior to depositing the liquid-impervious material onto the at least one mold. 10. An apparatus comprising: a containment structure comprising free-standing flexible walls and a floor, the walls and the floor comprising liquid-impervious material, the floor further comprising one or more first pieces of fabric, the floor being seamless with the walls; andflexible supports connecting the floor and the flexible walls, each flexible support comprising liquid-impervious material on one or more second pieces of fabric having a first end connected to the floor and a second end connected to an inner surface of one of the walls such that the one or more second pieces of fabric are positioned entirely within a space between the walls and above the floor. 11. The apparatus of claim 10, wherein the flexible walls contain no pieces of fabric. 12. The apparatus of claim 10, further comprising liquid-impervious material on an underside of the containment structure. 13. The apparatus of claim 10, wherein the free-standing flexible walls are configured to be repeatedly depressed and to return substantially to their pre-depressed shape. 14. The apparatus of claim 10, wherein the containment structure is configured to be rolled without removing any portion of the free-standing flexible walls and any portion of the flexible supports. 15. The apparatus of claim 10, wherein the first and second pieces of fabric comprise felt. 16. The apparatus of claim 10, wherein the liquid-impervious material comprises polyurea. 17. The apparatus of claim 10, wherein each flexible support consists of the liquid-impervious material on the one or more second pieces of fabric. 18. The apparatus of claim 10, wherein, for each flexible support, the liquid-impervious material on the one or more second pieces of fabric connects the flexible support to and holds one end of the flexible support against the inner surface of one of the walls. 19. An apparatus comprising: a containment structure comprising free-standing flexible walls and a floor, the walls and the floor comprising liquid-impervious material, the floor further comprising one or more first pieces of fabric, the floor being seamless with the walls;multiple flexible supports connecting the floor and the flexible walls, each flexible support comprising liquid-impervious material on one or more second pieces of fabric having a first end connected to the floor and a second end connected to an inner surface of one of the walls such that the one or more second pieces of fabric are positioned entirely within a space between the walls and above the floor; andmultiple tabs located at one end of the containment structure, each tab comprising liquid-impervious material on one or more third pieces of fabric, the tabs defining openings configured to receive fingers of a forklift. 20. The apparatus of claim 19, wherein: the first, second, and third pieces of fabric comprise felt; andthe liquid-impervious material comprises polyurea. 21. An apparatus comprising: a containment structure comprising free-standing flexible walls and a floor, the walls and the floor comprising liquid-impervious material, the floor further comprising one or more first pieces of fabric, the floor being seamless with the walls;multiple flexible supports connecting the floor and each of the flexible walls, each flexible support comprising liquid-impervious material on one or more second pieces of fabric having a first end connected to the floor and a second end connected to an inner surface of one of the walls such that the one or more second pieces of fabric are positioned entirely within a space between the walls and above the floor; andone or more handles, each handle connected to the floor and sealed to the containment structure using liquid-impervious material. 22. The apparatus of claim 21, wherein each handle is weaved into one or more cuts formed in the one or more first pieces of fabric.
