Description

CON/SPAN is a modular precast system designed to provide economic, large volume stormwater detention or infiltration below grade. CON/SPAN’s distinctive arch top and vertical side walls maximize storage volume and provide structural integrity. Combining the CON/SPAN arch unit with precast walls and cast-in-place foundations allows for an array of configurations to meet nearly any site need. Construction of cast-in-place strip footings beneath CON/SPAN legs and end walls allow for a large open area in the center of each cell. These cells can be filled with crushed stone or granular material to allow for stormwater infiltration or recharge by percolating runoff through the granular material inside of the foundation. CON/SPAN system provides efficient stormwater detention in a variety of footprints. Installation on a base slab foundation can be made watertight, which is ideal when dealing with high water table issues or subgrade soils sensitive to water infiltration. CON/SPAN can be combined with the Stormwater Management StormFilter to provide high-volume stormwater treatment. Distinctive shape; arch top and vertical side walls Maximizes storage space; superior durability and structural integrity Full range of span & heights Versatile design capabilities Precast continuous foundation Ensures structural integrity and eliminates differential settlement Manufactured in quality controlled environment Superior quality over cast-in-place Base slab, strip, or pedestal wall foundations Foundation versatility The CON/SPAN precast elements are three-sided arch units that offer rapid set-in place construction.
