Lane Enterprises’ StormKeeper family of chambers offers maximum performance, storage efficiency and value in a smaller footprint. The SK180 and SK75 chambers are injection molded from virgin polypropylene and designed with finite element analysis (CANDE) techniques to deliver high structural integrity and arch stiffness. The chambers, which exceed ASTM F2418, offer complete reliability to the engineer designing a retention or detention system, and provide the ability to meet almost all site elevation constraints.
