Precon’s Multi-Panel Vault structure is engineered as a multi-piece structure that is assembled on-site. It is highly versatile, which allows for a larger more customizable structure. Installation is quick and easy and can be backfilled immediately. The structure can be configured as a single storey or two storeys with an intermediate floor. It is also highly customizable to meet most design requirements using integrated splitter walls, weir walls, and intermediate floors, allowing for wet well/dry well combinations, energy dissipation and access to large mechanical or valve equipment.
