Geophysical Services
MGV Geotechnical Group, PSC, an offering geophysical services company, uses a variety of geophysical methods to solve engineering, geological, environmental and forensic problems. The methods and instruments we use are chosen to meet the specific needs of our clients and accommodate the existing field conditions.
Geophysical exploration has been utilized in numerous fields to o study a wide range of targets within the earth from discovering the deep structure of the earth at thousands meters to near surface structures and properties at depths of a few tens of meters. Some of the latest geophysical technologies are targeted at studying engineered material, such as pavements and bridge decks at only a few centimeters depth. Geophysical surveys are conducted on the ground surface, within drill holes, and from the water and air.
Non Destructive Testing (NDT) geophysical investigations are applied in two modes; parametric studies such as measuring and analyzing seismic velocity for determining the modulus of soils or concrete pavement, and imaging and mapping studies such as using ground penetrating radar (GPR) to look for trends that can be correlated to delaminations on a bridge deck among other non-transportation related projects.
Subsoil Drilling & Sampling
Drilling and Sampling Services for geotechnical and environmental projects are provided by MGV Geotechnical Group, PSC in a daily basis. In addition to the installation of wells.
At MGV Geotechnical Group, we offer Cone Penetration Testing (CPT) as part of our in-situ soil investigation services, providing accurate and continuous profiles of subsurface conditions. We also perform Seismic Cone Penetration Testing (SCPT), which measures shear wave velocity—a critical parameter for Site Classification in accordance with ASCE/SEI 7-22. This advanced testing method enhances the reliability of seismic site response evaluations and supports informed foundation design and ground improvement decisions.
Auger Drilling:
Often used for site investigation, environmental and geotechnical drilling and sampling, and boreholes for construction purposes, auger drilling can be an efficient drilling method. The advantages include low operating costs, fast penetration rates in suitable formations and no contamination of samples by fluids. Continuous flight augers with hollow stems are used for sample recovery in environmental, geotechnical operations.
Air Rotary Drilling:
Rotary drilling uses a sharp, rotating drill bit to dig down through the Earth’s crust. Much like a common hand held drill, the spinning of the drill bit allows for penetration of even the hardest rock. The basic rotary drilling system consists of four groups of components; the prime movers, hoisting equipment, rotating equipment, and circulating equipment all combine to make rotary drilling possible. The circulating agent, which is the responsible for lifting the cuttings to the surface and cooling the drilling bit, may be either water (with or without additives-mud) or air. Pumps are used when water is used while an air compressor is used for air.
Odex Drilling:
A special hammer drill bit is designed to be used inside and at the bottom of steel casing so that the drill bit has an eccentric reamer below the steel casing. With this method the hammer pulverizes the material below the casing and then blows it back through the casing to the top of the hole with the aid of an air compressor. As the hammer drives through the material, it also reacts against interior shoulder beveled inside the steel casing, which pulls the casing down the hole as the hammer drill is advanced. This method is well suited for drilling through difficult formations such as rock fill and back fill.
Air Rotary Drilling:
The DPT Direct Push Drilling Technology allows for a wide variety of direct push tooling and instrumentation to be advanced into a subsurface lithology using the static weight of the rig, hydraulic down pressure, and rapid hydraulic hammering. Direct Push Tooling is used to perform soil, soil gas, and groundwater sampling. It is also used for soil remediation, and geotechnical sampling and testing. Compared to conventional drilling, direct push drilling is less labor intensive, offers quicker setup time, and generates less drill cuttings. Direct push tooling is also easier to decontaminate and maintain.
