Patent number: 8936412Abstract: A seismic-resistant fluid reservoir cover includes a plurality of panels and a network of flexible membranes coupled to adjacent panels. The flexible membranes are made of a potable water approved material, and the panels and the membranes create a fluid tight seal. Each panel in the reservoir cover is able to move along three directional axes independently of the adjacent panels while maintaining the fluid tight seal, at least in part because of the flexibility or the slack in the flexible membrane. A support member, such as a backer rod, may also be positioned in the spaces between the panels.Type: GrantFiled: July 16, 2012Date of Patent: January 20, 2015Assignee: Versaflex, Inc.Inventor: Joseph Haydu

Patent number: 8499394Abstract: A waterproof expansion joint comprises a ballast protection plate with one or more centering tabs. Waterproof receptacles, or T-cups, are used to provide a waterproof layer under the ballast protection plate and around the centering tabs. Sealing tape and a spray-based waterproof membrane are installed with the T-cups. Once the ballast protection plate is placed over the deck joint with centering tabs extending downward into the T-cups, a bond breaker is applied. Finally, a second layer of waterproof membrane is applied to the top of all elements of the waterproof expansion joint.Type: GrantFiled: May 24, 2012Date of Patent: August 6, 2013Assignee: Versaflex, Inc.Inventor: Joseph Haydu
