Our Story

Read More

Soiltesting, Inc is a geotechnical drilling contractor providing service in the pre to post construction phases.Our pre-construction or design phase services include test borings services. Our construction phase services include pile installations including, helical piles, micro piles, StelCore piles, rock anchors and tiebacks. Our post construction services include underpinning for settlement correction including the installation of some of the previously  mentioned piles for the arrest and or reversal of foundation settlements.


We have experience working on a vast array of project types and sizes from multiple weeks of test borings in lower Manhattan to one day of test borings in the hills of Western CT. From 200 micro piles in the Bronx to two helical piles in Southbury,CT. From multiple  bedrock tiedown anchors at SUNY Purchase to several micro piles for at a residence addition in Westchester.


SoilTesting, Inc was founded in 1958 by Robert J. DeAngelis (1928-2003), a Civil Engineer, in Ansonia, CT and is presently being managed at its current location in Oxford, CT by James A. DeAngelis, an Engineering Geologist (M.Sc., P.G.) with over 30 years experience in subsurface investigations.


With over 50 years experience in test borings, we understand the importance of having a knowledge of subsurface conditions for the design of foundations and we take this experience with us to projects in the feasibility, construction and settlement correction phases. We take pride in getting the information (with test borings) our clients need to design new foundations and carry this same regard into our pile installations and underpinning services.


The versatility of SOILTESTING, INC.‘s principals, associates and staff allows us to successfully and economically apply their talents and expertise to diverse projects for clients in Connecticut and New York.
