Deep-foundation services
The below-grade scope we bid, organized by what it accomplishes on your site: shore a deep excavation, protect the building next door, lower a basement, or carry load to competent strata.
- Flagship
Shoring & Earth Support
Soldier piles and lagging, sheet piles, tiebacks and bracing: the SOE sub scope, sized for tight Boston lots.
- Shore a deep excavation
- Protect the building next door
- Get a scoped SOE sub bid
Anchors
Soil and rock anchors — ground, helical, and micropiles — to reinforce foundations.
- Resist lateral and uplift loads
- Stabilize a slope
- Tie back a retaining system
Underpinning & Basement Lowering
Pit-and-pour underpinning for builders and GCs lowering basements, with micropiles where pits can't reach.
- Lower a basement
- Protect a party wall
- Carry loads to firmer bearing
Pile Driving
Driven foundation piles installed to capacity with production-rate efficiency.
- Reach design capacity fast
- Drive in difficult ground
- Compress the foundation schedule
Drilled Shafts
Augered, cased, and rock-socketed drilled shafts for high-capacity foundations.
- Socket into bedrock
- Carry heavy column loads
- Install low-vibration near neighbors
Soil Nailing
Fully grouted soil nails installed top-down to reinforce a cut in place, lift by lift.
- Retain a cut without tiebacks
- Build top-down as you excavate
- Stabilize an over-steep slope
Limited-Access & Low-Headroom Drilling
Compact limited-access drills for anchors, micropiles, and tiebacks under restricted headroom and tight access.
- Drill where a standard rig will not fit
- Work under restricted headroom
- Reach a site no track rig can access
Sheet Pile Walls & Cofferdams
Vibratory-driven and extracted sheet pile walls, cofferdams, and bulkheads for work below the water table.
- Cut off groundwater
- Build a dewatered cofferdam
- Extract and recover temporary steel
Micropiles & Pin Piles
Small-diameter, high-capacity drilled and grouted piles socketed into glacial till or bedrock.
- Underpin an existing foundation
- Install where access is tight
- Carry load through deep fill to ledge
Before design · before bid
Know the rock before it’s in the price
Factual ground data for the people carrying rock risk: a field program on one site, or a desk screen across many.
Pre-construction Ground Checks
Rock probes, a logged test shaft and proof tests before you design or bid — factual field logs plus our installed-cost range.
See ground checksGround Screening
A desk screen of 5–500 sites: nearest measured logs, rock-depth range and a foundation-risk tier for each.

How we work
A short path from plans to mobilization. We generally work as a subcontractor to general contractors.
- 01
Inspection
We review the geotechnical report, plans, and site constraints — adjacencies, access, schedule.
- 02
Quote in 3 days
You get a detailed, scoped quote within three business days, grounded in the subsurface conditions.
- 03
Start
We mobilize, install to the engineered criteria, and document the work for your records.
