Soil investigation may require an array of services, such as borings, in situ geotechnical sampling and seismic refraction among others. Being able to decide which testing and sampling procedures are ideal to undertake at each project site will provide a competitive edge, accompanied by a rigorous quality management system that will grow upon the changing needs and expectations of our customers. 

​

A quick review of fieldwork is mentioned: Site borings are necessary in order to obtain samples from the underground; it is ideal for the samples to be undisturbed and representative of the different strata. With this information, a two- or three-dimensional overview of a site may be detailed for the proper of sampling, like continuous flight auger, rotary drilling (double barrel) and wash-boring. Other methods like the Cone Penetration Test (CPT) and Dilatometer Test (DMT), as well as simple field excavation are done to examine and analyze any given site. 

 

There are numerous investigation techniques that are done in the field to accompany the borings; among the most valuable are permeability, plate- load and density tests.  Interpretation of subsoil conditions necessary to the design considerations. Borings can be done by several means; the most widespread sampling method is known Standard Penetration Tests (SPT), which is done by dropping a 140 lbs mass introducing a split-spoon sampler and counting the number of blows to advance.
