Service · Drilling

Know the ground first.

Soil borings, rock coring, monitoring wells and test pits — run with our own rigs and our own crews, so the schedule does not depend on a subcontractor's calendar.

The Brief

Everything above grade is a bet on what the borings said.

Foundation design, excavation support, dewatering and environmental liability all trace back to a handful of holes in the ground. Get the subsurface investigation wrong and every decision downstream inherits the error.

We own and operate our drilling fleet across the Tri-State area and South Florida, with crews who log their own samples and a laboratory in the same firm that tests them. One chain of custody, start to finish.

Our Quality. Runs Deep.

Capabilities

What we drill.

Geotechnical and environmental drilling on sites from open lots to occupied buildings with eight feet of headroom.

Soil borings

Standard penetration testing with split-spoon sampling, logged and classified by our own field personnel.

ASTM D1586

Rock coring

Diamond-bit coring with recovery and RQD logging to establish sound rock for end-bearing foundations.

NQ · HQ core

Monitoring wells

Installation, development and abandonment of groundwater monitoring and piezometer installations.

Environmental

Limited-access drilling

Track and portable rigs for basements, cellars, occupied buildings and sites with restricted headroom.

Restricted access

Test pits & probes

Machine test pits, hand augers and probes for shallow investigation and utility clearance.

Shallow

Instrumentation & monitoring

Inclinometers, settlement points and vibration monitoring installed alongside the investigation.

Instrumentation

How a boring is run

Four steps from mobilization to the filed boring log.

Every depth, sample and N-value on a Universal boring log comes from this sequence.

Deliverables

What comes out of the hole.

LOG

Boring logs

Stratigraphy, blow counts, recovery and groundwater, logged in the field and drafted to scale.

LAB

Laboratory results

Classification, gradation, consolidation and strength testing performed in our own laboratories.

PLAN

Boring location plan

Surveyed locations and elevations tied to the site plan, not paced off a property line.

REPORT

Geotechnical report

Foundation recommendations and design parameters sealed by a licensed engineer.

WELL

Well records

Construction diagrams, development records and regulatory filings for each installation.

PERMIT

Permits & clearances

Drilling permits, utility mark-outs and street occupancy handled before the rig mobilizes.

How We Work

Cleared, drilled, logged, sealed.

Owning the rigs means the sequence below runs on our schedule, not a subcontractor's.

Permits & utility clearance

Drilling permits, mark-outs and street occupancy are resolved before mobilization, with private utility locating where required.

Access & setup

We match the rig to the site — truck, track or portable — so restricted headroom and occupied buildings are not an obstacle.

Drilling & sampling

A field geologist or engineer logs the hole as it is drilled and recovers samples under chain of custody.

Laboratory & analysis

Samples go to our own accredited laboratories for classification and strength testing — no handoff to a third party.

Engineering & closure

A licensed engineer interprets the data into design parameters, and every hole is grouted and closed to regulation.

The cheapest boring program is the one that does not have to be repeated after the excavator finds something else.

Where to next

Send the site address, the proposed structure and any access constraints. We will scope a boring program and confirm rig availability within one business day.
