Newark grew up fast—on glacial till near the Watchungs, on filled marshland along the Passaic, and on tight urban lots where history runs deeper than the sewer lines. Knowing what’s actually under the footing matters. Our team runs exploratory test pits throughout Newark, from Ironbound warehouse conversions to university expansions, using a compact excavator that threads into alleys where a drill rig can’t breathe. We open the ground, log the strata face-to-face, and pull bucket samples that show exactly where fill ends and native clay or varved silt begins. For deeper refusal data, the same crew frequently pairs the pit with SPT drilling to carry the profile down past the reach of the bucket.
You can read all the historic fill maps in the world, but nothing replaces standing next to an open cut and seeing the top of the varved clay yourself.
