Concrete & Foundations
Foundations, slabs, footings, and structural concrete work done right the first time. A strong foundation is the cornerstone of any successful construction project.
A solid foundation is the most critical element of any structure. JZ Development provides professional concrete and foundation services across Long Island, from new construction foundations to repairs and flatwork.
Our concrete work includes new foundation construction, footings, slabs, basement floors, driveways, sidewalks, steps, porches, and decorative stamped concrete. We use quality concrete mixes appropriate for Long Island's soil conditions and climate, and our experienced crews deliver level, properly-cured results on every pour.
Foundation repair is another core service. If you've noticed cracks in your foundation walls, uneven floors, or water intrusion, these issues need prompt attention. We assess the root cause, develop a repair plan, and execute the work properly — whether that means crack injection, underpinning, waterproofing, or partial reconstruction.
Whether you're building new or maintaining existing concrete, JZ Development brings the expertise and equipment to get the job done right. We work within your budget to recommend the right approach — whether that's a targeted repair or a full replacement. We've poured foundations across Nassau and Suffolk County for homes, additions, garages, and commercial projects.

Decorative stamped concrete patios, walkways, and driveways that mimic the look of natural stone, brick, or tile at a fraction of the cost. We offer a wide range of patterns and colors to complement your home.

Frequently Asked Questions
How do I know if my foundation needs repair?
Signs that your foundation may need repair include visible cracks in foundation walls or floors, doors and windows that stick or won't close properly, uneven or sloping floors, water intrusion in the basement, and gaps between walls and ceiling or floor. If you notice any of these signs, we recommend a professional inspection.
How long does a concrete driveway last on Long Island?
A properly poured and maintained concrete driveway on Long Island typically lasts 25-30+ years. Factors that affect longevity include proper base preparation, adequate thickness, control joints, sealing, and avoiding de-icing chemicals that can damage the surface.
What is the difference between a slab and a full foundation?
A concrete slab is a flat, horizontal pour that sits at or near grade level — common for garages, patios, and some home floors. A full foundation includes vertical walls (typically 8-10 feet) that create a basement or crawl space below the structure. Full foundations provide more structural support and usable space.
Do you pour concrete in winter on Long Island?
We can pour concrete during Long Island winters with proper cold-weather precautions including heated enclosures, insulated blankets, and accelerated concrete mixes. However, optimal conditions are typically spring through fall. We'll advise you on the best timing for your specific project.
How much does a concrete driveway cost on Long Island?
A new concrete driveway on Long Island typically costs $8-$15 per square foot, with most residential driveways running $3,000-$8,000 depending on size, thickness, and finish. Stamped or decorative concrete costs more. We work with homeowners to find the right solution for their budget — whether that's a standard finish or something more custom. Free estimates, transparent pricing, no pressure.
How much does stamped concrete cost per square foot on Long Island?
Stamped concrete on Long Island typically costs $12-$25 per square foot, depending on the pattern complexity, number of colors, and the size of the project. A standard stamped concrete patio (300-500 sq ft) usually runs $4,000-$10,000. It's more affordable than natural stone while providing a similar aesthetic.
Is it cheaper to repair or replace a concrete driveway?
It depends on the extent of damage. Minor cracks and surface spalling can often be repaired for $500-$2,000, making repair the better value. However, if the driveway has extensive cracking, heaving, or settling, a full replacement is usually more cost-effective in the long run. We provide honest assessments and won't recommend replacement if a repair will do the job.
What causes foundation cracks on Long Island?
Foundation cracks on Long Island are commonly caused by soil settlement, hydrostatic pressure from groundwater, freeze-thaw cycles, tree root pressure, and poor original construction. Sandy soil conditions in parts of Suffolk County and clay soils in Nassau County each create unique foundation challenges. Early detection and repair prevents cracks from becoming major structural issues.
