Concrete Slabs

Concrete slabs are the foundation of countless residential and commercial projects on Long Island, providing a flat, stable, and durable surface for garage floors, workshops, outdoor storage areas, and building foundations. Brothers Paving & Masonry specializes in slab installation across Nassau and Suffolk County, delivering precision-engineered slabs that meet your project's structural and performance requirements.

Every installation starts with a comprehensive site evaluation covering soil conditions, drainage, load requirements, and local code. Long Island's geology varies, from loose sandy soil in coastal communities to denser clay inland. We excavate eight to twelve inches below finished grade, then install four to six inches of compacted crushed stone with geotextile fabric where soil conditions demand it. Forms are set to exact elevations using laser levels, and reinforcement, either welded wire mesh for standard slabs or rebar grids for heavier loads, is installed based on the slab's intended use.

We use a minimum 4,000 PSI air-entrained mix from reputable Long Island ready-mix plants, tailored to each application. Garage floors receive a steel-trowel finish for smoothness, while outdoor slabs get a broom finish for traction. Control joints are placed at calculated intervals to manage shrinkage cracking, and expansion joints separate the slab from existing structures. After finishing, a curing compound ensures proper hydration and full design strength. Our team is familiar with building code requirements across Nassau and Suffolk County municipalities, including minimum thickness, reinforcement specs, and vapor barrier standards.
