Subsurface injection of remediation substrates is commonly performed with a direct push rig driving vertical injection points. While this method is common, it doesn’t provide a solution for the injection of substrate under obstructions such as roadways or building foundations. Following months of collaboration between Ellingson-DTD and Innovative Environmental Technologies, Inc. (IET), we have designed tooling and methodology for un-screened, direct injection of substrates utilizing horizontal directional drilling methods. Ellingson-DTD/IET crews drilled and injected substrate into 24 horizontal directionally drilled borings under active multi-lane roadways. The total footage was about 3,855’ for an average length of 161’ per bore. Once a boring was completed, the guidance tooling was removed and the direction injection tooling inserted. The injection tooling seals against the horizontal bore hole walls and substrate was injected under pressure into the injection zones. Approximately 1,000,000 pounds of modified permanganate solution for the purpose of mass removal and flux reduction were placed in the subsurface. #horizontalenvironmental #contamination #groundwater

Ellingson-DTD crews installed two blind, (single entry) horizontal air sparge wells at a former compressor station. Both wells started on the location; one well was terminated offsite under an active roadway and the second well was installed entirely on the site. Three-inch, high density polyethene (HDPE) well screen (Air Diffusion Systems) and casing were utilized for the well materials. The average well length is 283’ with 130’ of screen installed in each well. The formation at the site includes compacted sand/silt, clay and coal. Biopolymer drilling fluid was utilized for the drilling and well installation operation and well development consisted of fresh water and enzyme flushing and jetting followed by pumping to remove residual water. #horizontalenvironmental #contamination #groundwater

AMOSTECH - Mission Magnum I Vertical Centrifugal Pump  The vertical Mission Magnum Mud Pump is a single stage vertically mounted centrifugal pump which is easy to operate /maintain and small footprint.The shaft of the Mission sand pump directly connect the electric motor, there no need to install the bearings and mechanical seal. Concentric casing design minimizes shaft cyclical deflection and allows excellent slurry handling. Vertical Centrifugal Mud Pump Applications: - Mud pumping -offshore/onshore - Solids control - Dredging - Leveling or Rig Platform(ballast)

6 Methods for Pile Foundation Testing Method Pile foundation serves as the primary load-bearing component of structures, directly impacting their safety and longevity. However, being a concealed engineering aspect, the evaluation and judgment of its quality necessitate professional inspection methods. Pile foundation engineering encompasses various classifications, typically categorized by load-bearing capacity into friction piles, end-bearing piles, and combined friction-end bearing piles. Pile foundation inspection technology has evolved from the limited use of sonic echo methods in the late 1980s to comprehensive surveys employing low-strain, sonic echo, static loading tests, core drilling, high-strain testing, and other integrated approaches. #pilefoundation

What’s the Next Big Thing in Pipeline Protection? With the increased deployment of horizontal directional drilling (HDD) technology, there is a growing need during installation to protect pipeline coatings intended to resist corrosion. Indumar's ARO products integrate cutting-edge materials with an easy to install format for unmatched abrasion resistance and toughness. #InduMar #ARO #PipelineProtection #InnovationC80

Integrating additional cleaning elements, such as magnets, into a pig will significantly enhance the pipeline cleaning process. It is common for pipelines to be cleaned without the use of magnets, leading to the assumption of a clean line when no debris is retrieved. However, the presence of ferrous debris becomes evident only when an In-Line Inspection (ILI) tool is used. As ferrous metal can compromise an ILI survey, pipeline operators must use a cleaning pig equipped with magnets to ensure the complete removal of ferrous material. Our proactive approach ensures that the best recommendations are implemented from the outset, guaranteeing optimal cleaning results with each pig pass. #pipelineintegrity #pigging #pipeline #oilandgas #pipelinemaintenance

Self drilling anchor bars are widely used in ground foundation engineering. They can be used as micropiles.
