AREAS OF EXPERTISE
Concrete & Foundation Construction
We specialize in structural concrete and foundation construction for residential and small-scale development projects throughout the Bay Area. From footings and slabs to driveways and retaining walls, every project is built to engineered elevation, compacted subgrade, and city inspection standards for lasting strength and precision.
Structural Foundations & Footings
We construct house foundations, ADU pads, footings, and grade beams built to plan and engineered elevations. All foundations are excavated, formed, reinforced, and poured with verified subgrade compaction and proper rebar placement, ensuring long-term structural integrity and inspection approval.
Concrete Slabs and
Flatwork
Our crew installs concrete slabs, patios, and walkways with precision, finish, and durability in mind. From basement and garage slabs to architectural concrete surfaces, we ensure proper base rock, vapor barrier installation, and finishing techniques for a clean, crack-resistant surface.
Driveways, Aprons & Access Pads
We handle full driveway installations, replacements, and site access slabs using graded base rock and reinforced concrete. All driveways are compacted, poured, and finished to achieve proper slope, drainage flow, and city approach standards.
Retaining Walls & Concrete Reinforcement
We build concrete retaining walls, grade separations, and hillside stabilization structures using rebar cages and structural tie-backs where needed. Each wall is engineered for load, drainage, and soil conditions, ensuring stability and longevity on challenging Bay Area terrain.
