Stable Support for What You're Building

Foundation Construction in Long Island

When you're adding to your home or building a new structure, the foundation has to support the load, sit level, and resist settling over time. On Long Island, that means accounting for soil composition, water table levels, and how the ground reacts to seasonal changes. Lorenzo Napolitano Construction INC handles foundation construction for residential and light commercial projects where the excavation, grading, and concrete work are all managed in-house.

The service includes site prep, excavation, base compaction, forming, and pouring for new construction, additions, garages, and exterior structures. Because the same crew handles both excavation and concrete placement, the process moves efficiently without waiting on separate contractors. Foundations are built to meet structural load requirements and local soil conditions across Long Island, and the work integrates with masonry, framing, and other phases of the project.

If you're planning construction that requires a foundation, contact us to schedule a consultation and review what your site needs.

What the Work Includes and How It Connects

The process starts with excavation to reach stable soil and remove anything that would cause settling later. On Long Island properties, that often means digging through topsoil and loose material until the base is solid and drains correctly. The base is graded, compacted, and checked for level before forms are built and rebar is positioned according to the structural plan.

Once the concrete is poured and cured, you'll see a foundation that sits level, resists cracking under load, and connects cleanly to the rest of the structure. The edges remain straight, the surface is smooth enough for framing or masonry, and water drains away from the perimeter instead of pooling against the concrete.

The service includes excavation, grading, forming, rebar placement, concrete pouring, and finishing. It does not cover underground plumbing, electrical conduit, or interior slab finishing unless specified. If your project requires permits or engineering drawings, those are coordinated separately, but the foundation work follows the approved plan and inspection schedule.

Foundation work brings up questions about timing, soil conditions, and how the process fits into the overall construction schedule.

Questions That Come Up Before Starting

What types of foundations does this service include?
The service includes poured concrete foundations for homes, additions, garages, sheds, and exterior structures. It also covers footings, slabs, and foundation walls depending on what the project requires.
How long does it take to complete a foundation?
Most residential foundations take between one and two weeks from excavation to final cure, depending on size, access, weather, and inspection requirements. You'll get a timeline once the site and project scope are reviewed.
Why does soil condition affect foundation work?
Soil determines how much the foundation will settle and how well it drains. Sandy or loose soil requires deeper excavation and more compaction to create a stable base that won't shift under the weight of the structure.
What happens if water collects in the excavation?
Water is pumped out and drainage is adjusted before concrete is poured. If the water table is high, the base may need additional grading or stone to keep water from undermining the foundation after it's in place.
When can framing or masonry start after the foundation is poured?
Concrete needs at least seven days to cure before heavy loads are placed on it, though full strength takes about 28 days. Framing and masonry can begin once the foundation passes inspection and reaches the required cure time.
