Pouring Foundations and Slabs That Last

Concrete foundations and flatwork installation in Yonkers for residential and light commercial construction projects.

A concrete foundation must support the weight of a structure for decades without cracking, settling, or shifting in Yonkers where freeze-thaw cycles and soil movement test every footing. A.M.C. Excavation, LLC installs reinforced concrete foundations, slabs, pads, and flatwork with proper base preparation, rebar placement, and finishing techniques that meet structural standards. Whether you are building a new home, adding a garage, or pouring a patio in Yonkers, the pour begins with a stable, level base and ends with cured concrete ready to carry load.

Foundation work includes footing excavation, formwork installation, rebar placement, and concrete placement. Footings are dug below the frost line and poured to distribute building loads across stable soil. Slabs are placed over compacted gravel base with vapor barriers installed to prevent moisture migration. Flatwork such as sidewalks, driveways, and pads is finished with brooms, trowels, or floats depending on the intended surface texture and use.

A.M.C. Excavation, LLC coordinates concrete pours in Yonkers to ensure delivery, placement, and finishing happen on schedule and to specification.

How Foundations Are Built to Support Structures

Foundation installation in Yonkers begins with excavation to the depth shown on structural plans. Forms are built to the correct dimensions and braced to prevent bulging during the pour. Rebar is tied in grids or cages to reinforce the concrete and prevent cracking under load. Anchor bolts are positioned before the pour to secure sill plates and framing.

After the concrete cures, you will see level, solid footings or slabs ready for framing or finishing. Foundations are poured in lifts if depth exceeds standard formwork height. Slabs are screeded to grade, floated smooth, and control joints are cut to manage shrinkage cracking. Cold weather pours are protected with blankets or heating to maintain curing temperatures.

Mix design is selected based on load requirements, exposure conditions, and frost resistance. Concrete is placed within two hours of batching to ensure proper hydration and strength. This service does not include plumbing rough-ins, radiant heating installation, or decorative stamping. It delivers structural concrete built to code and ready for the next phase of construction.

Concrete Work Raises Practical Concerns

Homeowners and contractors planning concrete pours often have the same questions about curing, cracking, and timing. These answers cover what you need to know before the truck arrives.

How long does concrete take to cure?
Concrete reaches initial set in 24 to 48 hours but continues to gain strength for 28 days. Footings can usually be loaded for framing after 3 to 7 days depending on weather and mix design.
Why are control joints cut into slabs?
Control joints create planned weak points where concrete can crack as it shrinks during curing. This keeps random cracks from forming in visible areas and allows slabs to move without structural damage.
What causes concrete to crack after installation?
Cracking is usually caused by shrinkage during curing, freeze-thaw cycles, settlement of the base, or insufficient reinforcement. Proper base compaction, rebar placement, and joint spacing reduce cracking risks.
How thick should a residential foundation slab be?
Most residential slabs in Yonkers are 4 inches thick for garages and light structures. Heavily loaded areas or slabs supporting equipment may require 5 to 6 inches with additional reinforcement.
When can flatwork be poured after excavation?
Flatwork can be poured as soon as the base is excavated, graded, and compacted. Forms must be set and inspected before the pour is scheduled. Weather conditions and concrete availability determine the exact timing.
