Pond Embankment Stabilization with Geopolymer Injection

 

Geopolymer injection to sto seepage[Editor] An effluent pond in southeast Texas was suffering from years of erosion.  Recently, an escalation of subsurface water seepage through the pond’s embankment threatened the community’s main water source. URETEK used their versatile geopolymer product to inject beneath the embankment to seal off the seepage.  The project was a huge success!

Hayward Baker Breaks Ground on Recently Awarded K-10 South Lawrence Trafficway Ground Improvement Project in Lawrence, Kansas

Hayward Baker is performing stone column work at two main sites for the Kansas Department of Transportation’s K-10 South Lawrence Trafficway project in Lawrence, Kan., with over 6,800 thirty-six-inch diameter stone columns to depths up to 62 feet.Hayward Baker (HB) recently began work on a $9.1 million ground improvement contract for the K-10 South Lawrence Trafficway (SLT) Project located in Lawrence, Kan. as a subcontractor to Emery Sapp & Sons, Inc. The project provides a significantly improved transportation infrastructure for the state, making it a top priority for the Kansas Department of Transportation (KDOT).

Current construction will complete the southern K-10 bypass from its intersection with US 59 to the existing K-10 east of Lawrence. Construction affects 58 acres of wetlands. However, mitigation agreements between KDOT, local government agencies, and the public will create and restore 317 acres of wetlands as well as restore, preserve, and create over 50 acres of habitats.

Review of GeotechTools.org – Geo-Construction Information and Technology Selection Guidance

GeotechTools.orgI first heard about Geotech Tools through a TRB Strategic Highway Research Program (SHRP 2) publication titled Geotechnical Solutions for Soil Improvement, Rapid Embankment Construction, and Stabilization of the Pavement Working Platform. The final version of the report was released in February of this year. The report is one of the project deliverables for the SHRP 2 Project R02.

The primary deliverable of the project and the subject of this review is Geotechtools.org, a web-based tool for geotechnical engineers, structural engineers and pavement engineers. This website is a “toolkit of geotechnical information to address all phases of decision making from planning to design to construction.” What does that mean exactly? Great question. In this article I will give you an overview of the site and its resources and how it might help you on your next project.

Stabilizing Wind Energy

Generic wind turbine photo

Recently, URETEK ICR was asked to review a project involving lifting and stabilization of 10 precast transformer pads at a wind farm located in South Dakota.

The pads had settled to varying degrees with 8 of the 10 having settled 1 (±0.5) inch and requiring only stabilization and the two remaining, with settlement in excess of 3.5 inches, requiring lift and stabilization.

Design Guidelines for Increasing the Lateral Resistance of Highway-Bridge Pile Foundations by Improving Weak Soils

Lateral loads on bridges can result from earth pressure, seismic forces, wind loads, traffic or even ship impact or wave action. In cases where lateral loads govern, it is not uncommon to see designers add […]
