A Little Bit of History
Julia and Mike Sigalovsky lived and worked in the former Soviet Union till 1989. Graduates of the Moscow State University, Geology Department, they have participated in many geological, geophysical and mineralogical expeditions all over the country. Some of their expeditions included geological survey in Crimean and Ural Mountains, geophysical survey for oil in Kazakhstan and on the shelf of Baltic Sea, oil and gas survey in Siberia, hydro-geological investigations in the Central Russia region.

Drilling on Land
During 1997-1999, GeoTek Engineering, Inc. purchased 9 state-of-the-art drill rigs completely tooled with all new equipment allowing to perform a wide variety of drilling operations: auger and casing drilling, crock coring, angle drilling up to horizontal drilling, sampling with split-spoons and Shelby tubes, direct push, large diameter auger work, etc. [Click on the image to enlarge the picture]

Drilling on Water
GeoTek is specializing on drilling from the water surface whether it is a pond or lake, river or ocean. GeoTek has built a special float which permits drilling from wide variety water body conditions, from shallow mountain streams to ocean harbor. Some interesting moments of loading rigs and drilling are shown. [Click on the image to enlarge the picture]

Geotechnical Photos
GeoTek never refuses work when it involves tricky or even seemingly impossible technical tasks or when access to the job location is difficult. We always find engineering solutions to the problem and save our client's projects. These are some examples of it. [Click on the image to enlarge the picture]


Central Artery/Third Tunnel Project in Boston, MA, Contract C09A7. Drilling for and installation of inclinometers inside the US Postal Office Annex Garage. Clearance of the Garage is 10 feet. Drilling was conducted from the roof of the Garage, through the Garage, and into the ground. High tide level was 3 feet above the garage floor level.

GeoTek installed a number of geotechnical instruments including inclinometers, piezometers and observation wells on the bottom of a 250 feet shaft for the Massachusetts Water Resource Authority's Metro West Water Supply Tunnel Project, Weston, MA


GeoTek designed and manufactured a High Accuracy Packer Test Apparatus and developed a special software to process and store the data. GeoTek conducted the rock permeability tests.		Multiplexer and Tiltmeter installed in the Red Tunnel, Boston, MA, to monitor the tunnel movements during construction of the Central Artery/Third Tunnel Project

Mike Sigalovsky installs a tiltmeter outside a 6-story historical building, at the roof level, using a man-lift. The tilt meter monitors the possible tilt of the building due to nearby construction on the Central Artery/Third Tunnel Project, Boston, MA		Installation of multi-point extensometer using spooled string method developed by Michael Sigalovsky.


GeoTek is currently installing instrumentation in a project using NATM (New Austrian Tunneling Method). We are placing various types of pressure cells in and around the tunnel walls. The technologies being used here are the cutting edge of tunneling technology. The instrument manufacturers want feedback from us because, some of the applications here have never been used before!
