Geotechnical investigation is a method of exploration of subsurface strata of soil. The main objective of geotechnical investigation is to conduct a series of field and experimental investigations; to check the suitability of type and depth of foundation for the desired structural requirements. A well-planned geotechnical investigation cuts down the cost of construction effectively to a significant extent.
The Geoprobe® DT22 Soil Sampling System is a direct push system for collecting continuous core samples of unconsolidated materials from within a sealed casing of Geoprobe® 2.25 in. outside diameter probe rods. Samples are collected and retrieved within a liner that is threaded onto the leading end of a string of Geoprobe® 1.25 in.
Geoprobe® machines can use 3.25 in. casing to set a 1.5 in. Prepacked Screen Monitoring Well or You can also use the Geoprobe® driven casing with an option to sample soil on the way down in the same hole. Depending on which Geoprobe® machine you have, you can also use 3.75 in. casing to set a 2 in Slim Prepack, or 6 in casing to create a 6 in borehole to set 4 in wells (for monitoring/dewatering)
The key to a comprehensive environmental assessment is the subsurface investigation. Ground penetrating radar (GPR) plays an integral part by providing a non-intrusive means of examining the subsurface for environmental hazards such as soil contamination, underground storage tanks, utility lines and drums.
The former and still current form of heating for buildings in a still large portion of New York has been fuel oil. Many buildings that use fuel oil have a fuel oil storage tank which some could be underground tanks (UST) or aboveground tanks (AST). Through time and because not all tanks are registered with the NYSDEC.
