Publication number: 20190218736Abstract: A thin erosion control mattress system and method of protecting coastal structures and riverbanks against bearing failure and erosion from waves and current is disclosed. The thin mattress system includes geotextile fabric bonded to a tensile element (such as geogrid) and sand/gravel or other fill material confined in the mattress with connection elements (such as rivets) at specific intervals. The geogrid, which can be biaxial or multi-axial, provides tensile strength for picking during installation, improving foundation support and rigidity to the mattress system. The rivets function as spacers and tension elements to prevent bulging of the mattress, and are designed and spaced to temporarily secure the mattress in place for uniform filling and installation. The bonded geotextile-geogrid mat is typically sewn on all sides and filled with sand or gravel at designated fill ports. Further, a method of fabricating the thin mattress system is provided.Type: ApplicationFiled: September 14, 2017Publication date: July 18, 2019Applicant: TENSAR INTERNATIONAL CORPORATIONInventors: JEFFREY FISKE, KORD J.

Patent number: 9243379Abstract: A primary earth penetrating mandrel formed of a hollow shell steel plate has an upper end and an open lower end joined by an upwardly and outwardly tapered wall. The mandrel is driven downwardly in the earth to simultaneously form a vertical cavity while compacting the sidewall of the cavity to provide structural integrity. The mandrel is then moved upwardly from the bottom of the cavity and aggregate is deposited in the bottom of the cavity following which the mandrel is lowered so that its lower end engages the deposited aggregate and densifies the aggregate by vertical vibratory action and static force with these steps being repeated until the pier top is near the surface of the earth. A second embodiment includes a conduit in the primary mandrel for injecting concrete or grout into aggregate previously deposited in the cavity.Type: GrantFiled: November 4, 2013Date of Patent: January 26, 2016Assignee: Geopier Foundation Company, Inc.Inventors: Kord J.
