New Foundation & Slab-on-Grade Construction

Soils, design and engineering come first

Soil type affects bearing capacity, drainage and how much the ground moves, so many projects start with a geotechnical report. Engineers then design the footings, the reinforcing steel and the slab thickness to carry the building and resist earthquakes. The contractor follows the plans, checks them against the site and coordinates required special inspections. If conditions differ from the report, such as fill or high groundwater, the plan may need to change. Share the survey, the plans and any soils report with the contractor early, and mention underground utilities or trees that could affect the excavation.

Forms, rebar, utilities and the pour

Excavation sets the depth and width of the footings, and forms hold the concrete in place. Rebar is tied to the specified layout and held off the ground with supports. Plumbing, electrical conduits and gas lines that pass through the slab must be in place and inspected before concrete is placed. The pour itself depends on weather, access and timing, with the crew leveling, screeding and finishing the surface before it sets. Ask how the crew will manage rain and runoff during construction, since muddy or flooded footings must be cleaned and re-inspected before concrete is placed.

Curing, drainage and protecting the work

Concrete gains strength over days and weeks, and good curing prevents cracks and weak surfaces. Vapor barriers, drainage and grading keep water away from the slab and footings, and waterproofing protects any walls below grade. Do not rush framing before the concrete has reached its required strength. Keep records of inspections, test cylinders and engineer letters, because they matter for future owners, lenders and insurance. Keep the engineer’s letters, inspection cards and concrete test results in a folder, because lenders and future buyers often ask for them.
