Our crews handle subgrade prep, reinforcement, placement, and finishing to spec, with on-site QC at every pour to hit strength and tolerance targets.
We core-test, inspect for cracking and finish quality, walk every joint and ADA transition with you, and hand over a slab cleared for full service load.

NJ Design & Build - Najmna 34 Google reviewsPosted on Google Christina Johnson I am writing to highly recommend Moe of NJ Design and Build for his exceptional work as a contractor. Moe and his team recently completed the construction of an Accessory Dwelling Unit (ADU) in my backyard for my father, and the entire experience was nothing short of excellent. From the outset, Moe impressed us with his professionalism, transparency, and deep knowledge of the construction process. He took the time to thoroughly understand our needs and offered valuable design insights, and helped us navigate every step of construction with patience and care. The quality of workmanship delivered by NJ Design and Build was outstanding. The ADU was built with great attention to detail, on time, and within the agreed budget. Moe maintained consistent communication throughout the project and was always accessible when needed, ensuring we were informed and comfortable with all decisions being made. His crew was respectful and skilled, a true reflection of his leadership and standards. What stood out most was Moe’s genuine care for our family's needs. He understood that this ADU was not just another project, but a home for my father, and he treated it with the same consideration and integrity he would for his own family. I would not hesitate to work with Moe again and wholeheartedly recommend NJ Design and Build to anyone in need of a reliable, skilled, and trustworthy contractor. They truly deliver on their promise of quality and client satisfaction. Thank you Moe and team for a job well done. Sincerely, Christina Johnson Poway, CAPosted on Google Nicole Abeid We hired Najmna to build an ADU in our backyard and the experience exceeded expectations.

They helped me build 2 ADUs and I appreciate their persistence in finishing the job as fast as possible.Posted on Google WTD MIC Engineering and permitting process was good and fairly seemless. Price was competitive and initial demolition was good as expected. Tile layer is skilled and professional. Some of finish carpenters, etc. we’re lacking experience and quality control as appeared to be a shortage ok skilled labor. Moe the GM was very responsive, flexible, and pleasant to work with.Posted on Google Sean Canto It was nice to be able to have everything done by one company, from architect to construction.Posted on Google Alan Reitman Did a great job fixing what another contractor really messed up. They are very professional and experts in what they do.
We are a licensed commercial general contractor that self-performs and supervises concrete work end to end, so durability, schedule, and code compliance live under one roof.
Our team has placed structural slabs, tilt-up panels, and high-traffic flatwork across retail, industrial, and mixed-use projects in San Diego. That experience translates into accurate estimates, fewer change orders, and pours that hit specified PSI on the first test.
Property owners and developers avoid the cost of juggling separate concrete subs, inspectors, and finish trades. We act as a single point of accountability — one contract, one schedule, one warranty — which protects margin and keeps the building open during construction.
Every commercial site has different load profiles, drainage realities, and tenant constraints. We build the scope around your operating hours, your customers, and your long-term facility plan, not a one-size-fits-all template.
Heavy-duty commercial concrete engineered for load tolerance, code compliance, and a service life measured in decades.
We specify high-strength mixes (typically 4,000–5,000 PSI for commercial flatwork, higher for structural) with admixtures for crack resistance, durability, and California climate exposure.
Rebar, dowels, and post-tension cabling are placed to engineered drawings, then cured and finished to ACI tolerances so the slab performs the way it was specified.
Parking lots, drive aisles, and loading docks are built with thickened edges, proper jointing, and reinforcement designed for delivery trucks and continuous traffic.
Stamped, stained, exposed-aggregate, and polished finishes for lobbies, plazas, and storefronts that read as premium and stand up to public use.
Ramps, curb cuts, detectable warnings, and walking surfaces are built to ADA slope, cross-slope, and accessibility standards, plus current California Building Code.
Phased pours, night work, and tight cure windows let us deliver on the promised handover date while keeping your business open and revenue moving.
Tell us about your site, your timeline, and the kind of traffic the slab needs to handle, and we will come back with a fixed scope and a real number — not a placeholder

We handle structural foundations, slab-on-grade, tilt-up panels, parking lots, sidewalks, ADA ramps, loading docks, and decorative interior flatwork. Scopes range from single-tenant build-outs to multi-phase site work for industrial and mixed-use developments.
Properly designed and maintained commercial concrete typically performs for 30 to 50 years, and structural foundations often longer. The variables are mix design, reinforcement, drainage, and finishing — get those right up front and you avoid most early failures.
Yes. We install conventionally reinforced, post-tensioned, and fiber-reinforced concrete based on engineered drawings and the loads your facility actually carries. This is standard for foundations, structural slabs, and high-traffic paving.
Yes. We deliver stamped concrete, acid-stained, integrally colored, exposed-aggregate, and high-gloss polished finishes for lobbies, retail floors, and exterior plazas, all sealed to resist staining and traffic wear.
Every accessible route we pour is designed to current ADA and California Building Code requirements — including running slope, cross-slope, landings, and detectable warnings — and verified before sign-off to protect you from compliance risk.
Most commercial flatwork and parking lot scopes run two to six weeks, while full structural foundations and large site work scale from there. We sequence pours and cure times around your operations to keep downtime as close to zero as possible.
