We know the ground because it’s ours.
all six New England states. Every area below sits on a different slice of the Boston Basin, and the ground is what decides the system. The notes are general to each area — not a substitute for a site-specific subsurface investigation.
Service areas
Where we work
Pick an area for the local subsurface note, the techniques that suit it, and the projects we've run there.
Seaport
Earth support, pile driving, and drilled shafts for deep-foundation work on Boston's Seaport — built on fill and marine clay, often tight against occupied structures.
Reclaimed waterfront: deep urban fill over thick Boston Blue Clay, with a high water table — conditions that demand careful support of excavation and dewatering control.
Back Bay
Tiebacks, underpinning, and earth support for Back Bay projects, where filled ground and adjacent historic foundations require a careful, low-movement approach.
Historic filled land over Boston Blue Clay; many buildings sit on legacy timber piles, so limiting ground movement near neighbors is paramount.
Cambridge
Deep foundations, underpinning, and support of excavation across Cambridge, engineered to the area's clay, till, and bedrock profile.
Glaciomarine soils with fill and Boston Blue Clay over glacial till and argillite — a profile well suited to driven piles and rock-socketed shafts.
Somerville
Pile driving, drilled shafts, and earth support for Somerville projects, founded on the area's till and bedrock where high capacity is required.
Fill and marine clay over dense glacial till and bedrock; competent deeper strata make high-capacity driven piles and drilled shafts effective.
