What's under Cambridge
The subsurface dictates the means and methods. Here's the profile we engineer for in this part of the city.
Illustrative — depths vary by site. Every project is driven by its own geotechnical report.
Glaciomarine soils with fill and Boston Blue Clay over glacial till and argillite — a profile well suited to driven piles and rock-socketed shafts.
- Urban Fill
- Variable density and obstructions make fill unsuitable for direct bearing; it is typically penetrated by piles and supported during excavation.
- Boston Blue Clay
- Sensitive to disturbance and prone to consolidation settlement; lateral support and dewatering control are critical to protect adjacent structures.
- Glacial Till
- High bearing capacity and low compressibility; an excellent founding stratum for driven piles and a competent layer to socket through.
- Argillite / Bedrock
- Provides the highest end-bearing capacity; drilled shafts can be socketed into rock for heavily loaded columns and uplift resistance.
How Cambridge’s ground drives our means and methods — support of excavation, dewatering control, and the founding stratum we drive or socket to.
Scope
What we install in Cambridge
The full below-grade scope a general contractor can hand to one subcontractor.
- Earth SupportSoldier piles, sheet piles, lagging, and tiebacks for secure excavation support.
- AnchorsSoil and rock anchors — ground, helical, and micropiles — to reinforce foundations.
- UnderpinningStructural underpinning with driven precast concrete piles to strengthen foundations.
- Pile DrivingDriven foundation piles installed to capacity with production-rate efficiency.
- Drilled ShaftsAugered, cased, and rock-socketed drilled shafts for high-capacity foundations.
