Foundation Excavation for Every Structure


Our experienced team and modern equipment are equipped to handle any type of residential or light commercial foundation project. We have deep expertise in the specific requirements for:

  • Full Basements
    We excavate to the precise depth and dimensions required for full basements, including preparing for walk-out basements on sloped lots, which are common throughout the Bethlehem region.

  • Crawl Spaces
    We provide accurate digging for crawl space foundations, ensuring proper depth for access and ventilation.

  • Slab-on-Grade Foundations
    We expertly excavate and prepare the ground for monolithic or floating slabs, including digging for frost walls and footings essential for stability in New Hampshire's climate.




The T's Advantage: Built for New Hampshire's Challenges


Excavating in Northern New Hampshire isn't like digging in sand. It requires local knowledge and the right equipment to overcome unique challenges.

  • Navigating Tough Terrain
    We have extensive experience with the rocky soils and granite ledge common in the White Mountains. We know how to handle these conditions efficiently to keep your project moving.

  • Integrated Drainage & Waterproofing Prep
    A dry basement starts outside the walls. We expertly install foundation footing drains and prepare the exterior walls for waterproofing, preventing the damp basement issues that can plague homes in our climate.

  • Precision Backfilling & Compaction
    How a foundation is backfilled is just as important as how it's dug. We carefully backfill and compact the soil in lifts to ensure even pressure and prevent future settling or structural issues.

  • Builder-Focused Reliability
    We work directly from your site plans, ensuring every corner is square and every dimension is exact. We pride ourselves on being a reliable partner who helps builders start their vertical construction without delay.
