Services
Foundations
We construct precision foundations using advanced forming systems and mechanical vibration techniques. Our process ensures perfectly square, flat, and smooth results with superior strength through proper rebar placement and concrete consolidation. With 40+ years of experience handling complex residential and commercial projects, we deliver code-compliant bases that serve as the critical starting point for successful construction.
Additions
Our team specializes in crawl space and full cellar additions that seamlessly integrate with existing structures. We employ embedded waterproofing between old and new foundations to create watertight connections, working with block, poured concrete, or stone bases. By combining excavation and concrete work, we simplify expansion projects while maintaining structural integrity.
Helical Piers
Through our partnership with PierTech, we provide helical pier solutions with digital torque monitoring for precise installation. Certified operators record average/final torque and depth data, which we provide to engineers for verification. This system ensures accurate placement to exact specifications, offering reliable support for challenging soil conditions across Cape Cod.
Excavation
We handle complete excavation projects for garages, retaining walls, and foundation additions. Our integrated approach combines digging with concrete work to eliminate coordination issues between contractors. This single-source solution reduces costs and timelines while ensuring proper preparation for foundation pouring and backfilling operations.
Waterproofing
Our embedded waterproofing system creates watertight connections between new foundations and existing structures. Installed during addition projects, this critical protection prevents water infiltration at transition points between different foundation types. The system works with block, poured concrete, or stone bases to maintain structural integrity and interior dryness.
