by:P.E. LaMoreaux & Associates, Inc. (PELA) based inTUSCALOOSA, ALABAMA (USA)
PELA GeoEnvironmental professionals are internationally recognized experts in the geology and hydrology of karst aquifers. Karst areas present unique hydrogeologic and engineering challenges because they are often characterized by sinkholes, underground (cave) streams, and major springs. PELA has performed major investigations of karst areas for ...
by:PBG Geophysical Exploration Ltd. based inWarsaw, POLAND
The surveys facilitate the identification of the structure of surface geological layers to the depth of planned foundation of objects and expected interaction of the groundwork with the ground; survey results allow to define zones of discontinuity of geological structures, fracture zones or karst sinkholes. ...
by:MicroSeismic, Inc. based inHouston, TEXAS (USA)
Damage to homes, businesses, factories, and infrastructure from sinkholes results in millions of dollars in repair and lost revenue every year. Sinkholes can appear suddenly at the surface (“daylighting”). When a karst/sinkhole “daylights, the ground literally drops out from under ...

Groundwater/Surface water Interactions. Peatland Hydrological Assessments. Flood Risk Assessments. Windfarm Hydrological Assessments. Karst Hydrology and ...
by:GeoView, Inc. based inSt. Petersburg, FLORIDA (USA)
The investigation of potential karst (sinkhole) activity at residential or commercial properties or undeveloped land is a multi-disciplinary process in which geophysics plays a critical role. Subsurface geology in karst environments is very complex and is often masked at the surface. ...
by:Brayman Construction Corporation based inSaxonburg, PENNSYLVANIA (USA)
The design called for the use of a minimum 11-3/4in OD casing and corresponding core steel to meet the required design capacities. With pile lengths from 50 to 150ft in length due to the karst characteristics of the local geology, drill casing availability became a major concern. With shortages in the supply of the 11-3/4in pipe, Brayman utilized other available sizes (11-7/8in ...
by:GEOSPECTRUM S.C. based inKrakow, POLAND
In contrast, tomography can localize more complex structures where seismic wave velocities change in different directions gradually. Such places are fault zones, areas of karst, voids. Refraction tomography uses 'first breaks' of refraction P-waves. The result of refraction tomography is determining velocity field in the tested ...
by:Earth Scan Technologies Ltd. based in, ALBERTA (CANADA)
LOZA is unlike any other GPR technology and offers unique, high-resolution imaging of the subsurface. Exceptional depth penetration of over 200 meters! Excellent resolution of mineralization, fractures, faults, karst, tunnels, leaks in dams and tailings ponds. Excellent for defining high quality mineralization with demonstrated success on mining projects globally. Efficient data ...
by:Patriot Engineering based inIndianapolis, INDIANA (USA)
During construction, what is under a piece of property can be just as important as what is being built on top of it. Contaminated soil, “old fill”, groundwater, karst topography, and more unknowns can be disastrous for a construction project. The following benefits make Patriot Engineers invaluable members of your engineering and design team. Patriot’s ...
by:Earth Resources Technology, Inc. (ERT) based inLaurel, MARYLAND (USA)
We routinely perform geophysical detection and/or mapping of landfills, buried debris including drums and abandoned USTs, various subsurface structures, contamination plumes, karst bedrock features, and archaeological remains. We have expanded our geophysical capabilities to include unexploded ordnance (UXO) detection and characterization. ...
by:POWER Engineers, Inc. based inAnaheim, CALIFORNIA (USA)
The geoscientists at Zephyr have the technical knowledge and capabilities needed to help our clients determine the feasibility of groundwater supply development, identify geologic hazards that could potentially impact land development decisions, and identify sensitive features (geologic and/or manmade) that hydraulically connect surface and karst aquifers. The sound geologic ...
by:Troy Risk, Inc. based inIndianapolis, INDIANA (USA)
Troy Risk provides its clients with the experience and expertise needed to successfully perform the full range of geophysical methods to solve challenging subsurface issues such as: Searches for historic or undocumented underground storage tanks (USTs), Mapping of concealed waste disposal areas, Location of buried drums and other waste containers, Utility and buried infrastructure mapping, ...
by:GeoView, Inc. based inSt. Petersburg, FLORIDA (USA)
It generates a swept frequency source to produce a high resolution image of the sub-bottom at penetration depths up to 50 meters. It is useful for mapping sediment thickness, karst surveys, conducting scour studies, mapping shallow geologic strata and mapping buried utilities and other submerged structures. The source and receiver are housed in a single towfish, allowing data to ...
by:Ridgeway Ecology based inWarwick, UNITED KINGDOM
Ridgeway Ecology staff have been involved in and led a wide variety of scientific research and monitoring activities ranging from autecological studies in the UK through to the ecological studies of bat communities in biodiversity rich countries. We also provide authoritative advice and reports to government organisations and leading ...

Frost GeoSciences has performed hundreds of Geologic Assessments along the San Antonio/Austin corridor, and is well-versed in the requirements and standards of the Texas Commission for Environmental Quality (TCEQ), formerly the Texas Natural Resource Conservation Commission ...
by:Simcoe Geoscience Limited based inStouffville, ONTARIO (CANADA)
Magnetic surveys measure small, localised variations in the Earth's magnetic field. The magnetic properties of naturally occurring materials such as magnetic ore bodies and basic igneous rocks allow them to be identified and mapped by magnetic surveys. Strong local magnetic fields or anomalies are also produced by buried steel ...
by:GeoView, Inc. based inSt. Petersburg, FLORIDA (USA)
Electrical Resistivity measurements are performed by placing multiple electrodes in contact with the soil or rock. Current is transmitted and received between pars of the electrodes. The surveys can be performed as traditional, single Vertical Electrical Soundings or with multi-channel systems to produce continuous resistivity cross-sections of the subsurface. The depth of investigation and ...
