Abstract:
A system for preventing fluid from entering a walled structure includes a support structure configured for fixing to at least one surface of the walled structure; and a barrier apparatus attachable and anchorable to the support structure, the barrier apparatus including a fluid retention member configured for intercepting a fluid entering the walled structure, and a collar for holding the fluid retention member against an interior surface of the walled structure, proximate the opening. As fluid enters the barrier apparatus, the pressure increases against the interior surface of the fluid retention member, pressing it against the walled structure. The collar in combination with the fluid retention member to which it is attached acts like a gasket to tighten a seal between the barrier apparatus and the walled structure.
