Recent Webinar on Injectable Barriers™ is Popular Learning Opportunity
The recent webinar Ground Works hosted on Injectable Barrier Walls, titled Trenchless Applications for Restricting Groundwater and Contamination movement, provided an excellent learning opportunity for engineers, environmental consultants or for those seeking to learn more about innovative applications for subsurface barrier walls, curtain walls or for stabilizing soils for trenching.
Robert W. Moody, Jr., Ground Works’ President, presented along with Tim Harmon, P.E. with Handex/HCR. They presented three case studies presenting environmental containment and control and seepage management for dams, dikes, levees, and water control structures. Some of these presentations included the FDOT SR7 Injectable Barrier Wall, FPL Headwall Installation and the Handex Consulting and Remediation FDOT Riviera Beach subsurface contamination groundwater restriction project.
The webinar lasted for about approximately 50 minutes, however the subject matter of the webinar must have highly intrigued the audience. Mr. Moody and Mr. Harman went on to…
Ground Works Featured in Trenchless Technology Article
In the July 2016 issue of Trenchless Technology, Ground Works Solutions’ CFO, Aaron Hall, writes about the successful rehabilitation of a box culvert in Pensacola, Florida. In the piece, Aaron discusses the problems created by historic flooding in Escambia County and how Ground Works Solutions was able to lift a box culvert structure by two feet in order to restore its long-term viability.

Combating Microbial Corrosion in Tunnels
Microbial corrosion, or microbiologically-influenced corrosion (MIC), is “the gradual damage to metal caused by the metabolic activity of microorganisms.” This corrosive damage has caused billons of dollars of damage to our water systems, especially our storm water and sewer systems, although MIC can happen wherever metal and water meet. Finding a solution for repairing corrosive damage depends on where it is occurring, why it is occurring, and how disruptive or expensive a repair or replacement will be.
There are several different types of bacteria responsible for MIC in metals located in soils and water; all are classified as either aerobic (requires oxygen) or anaerobic (oxygen is toxic). Sulfate reducing bacteria (SRB) is anaerobic and is responsible for most of the corrosion caused to steel in sea water; whereas, iron and manganese oxidizing bacteria are aerobic and are most often responsible for the rapid corrosion and pitting at welds in stainless steel. Microbial corrosion can also occur in plastics,…
Foundation Damage Caused By Melting Snow and Ice
The winter of 2015 will go down in the history books as one of the snowiest. In fact, as of March 15, 2015, Boston had accumulated a total of 108.6 inches of snow. This was the most amount of snowfall since the city started tracking weather back in 1872. It has also been a brutally cold winter across the entire Northeast. Once again, Boston broke records, averaging only 16.1 degrees in February.
After a long season of shoveling, snow blowing and digging out the car in order to go anywhere, warmer weather is a welcome signal that spring is almost here. Experts predict that this spring’s runoff from melting snow and ice will be the worst we’ve had in the last 15 years. Unfortunately, melting snow and ice can cause damage to houses and other buildings and may uncover some unwelcome cracks in the foundation. As a…
URETEK’s Safety Culture
Workplace safety is paramount at URETEK Holdings because of the many hazardous environments and conditions the work crews navigate on a daily basis. Everyone, including all of our clients and customers, wants our crews to be safe on the job. At one job site the crew may be dealing with power lines over their work space, at another job it could be working in the confined space of a storm drain, or along a busy highway, or rail road, or even working on a barge in the Everglades. Regardless of what the safety challenges are on each individual project, the URETEK crew is well prepared and trained to keep themselves and others safe on the job site. It all starts by creating a culture built on safety.
Recently, URETEK was given a 0.75 safety rating. This Experience Modification Rate (EMR) is given by the National Council on Compensation…
