Patent number: 10465355Abstract: Methods, and apparatuses used in those methods, of countersinking injection tubing below the surface of a structure, such as pavement, so that injection tubing will not extend above the surface of the structure even after movement of the soil, for example, due to frost heave or shrink-swell. Some embodiments employ an injection tube extension and/or an injection tube advancer to countersink the injection tubing within the soil beneath a structure.Type: GrantFiled: August 31, 2018Date of Patent: November 5, 2019Assignee: Uretek USA, Inc.Inventors: Brent J. Barron, Edward Hibbard, Matthew Sotirin, Chris Phelps

Patent number: 9988784Abstract: A method and apparatus for rapidly constructing a structural pier comprising the steps of placing into a soil under a structure to be supported a casing having an inner diameter and an outer diameter, positioning an injection tube into the inner diameter of the casing, and injecting an expansive material into the casing. Optional perforations in the casing allow some of the expansive material to be ejected from the casing into the surrounding soil to create fingers or branches for the purpose of adding friction to the structural pier.Type: GrantFiled: July 14, 2015Date of Patent: June 5, 2018Assignee: URETEK USA, INC.Inventors: Brent Barron, Randall W. Brown, Edward Hibbard

Publication number: 20170073919Abstract: The present invention relates to in-place soil stabilization. Specifically, the present invention relates a method and device for measuring the increase in subsurface earth pressure or soil displacement during the injection of a stabilizing agent into the soil and prior to surface movement. The rise in sensor pressure or displacement of soil indicates an increase in soil strength and bearing capacity. Therefore, real-time monitoring of these pressures or movements may serve as a guide during the injection process.Type: ApplicationFiled: November 28, 2016Publication date: March 16, 2017Applicant: Uretek USA, Inc.Inventors: Brent Barron, Michael Bock

Publication number: 20100272518Abstract: The present invention provides methods and apparatus for soil stabilization. First, a void is formed in the compromised soil strata. Then, an expandable member containing expandable materials is placed into the void. As the material expands to fill the void, the surrounding soil is compressed. This in situ compression if the soil increases the load bearing capacity and compressive strength of the soil. Additionally, the present invention provides a method for isolating the injected materials from the environment at the injection and/or polymerization point.Type: ApplicationFiled: April 22, 2010Publication date: October 28, 2010Applicant: URETEK USA, INC.Inventors: Brent Barron, Scott Brown
