Lightweight Concrete Supply in Flushing, NY: Reduce Dead Load Without Sacrificing Performance
When an engineer flags dead load as a structural concern, the solution isn't a workaround. It's the right mix.

Standard concrete weighs roughly 145 to 150 pounds per cubic foot. That's fine for grade-level slabs and foundations where the ground carries the load. On elevated decks, composite metal deck systems, floor toppings, and structural applications where dead load is a design constraint, that weight is a problem the engineer has already accounted for. Lightweight concrete, typically around 105 to 115 pounds per cubic foot, reduces that dead load without giving up the compressive strength the project requires. Call (718) 939-3245 to discuss your project.
Lightweight concrete belongs on the project when an engineer has specified it or when the structural design depends on reduced dead load. Elevated decks, topping slabs over existing structural slabs, composite floor systems on metal decking, multi-story building floors, and parking structures are the most common applications. It's also used in residential construction for radiant heat floor systems where the mix is placed over wood-framed decking.
If the spec calls for lightweight concrete and you substitute standard mix, you're delivering a heavier slab than the structural design accounts for. That's not a minor variance on an elevated structure.
WHEN YOU NEED LIGHTWEIGHT CONCRETE SUPPLY
OUR LIGHTWEIGHT CONCRETE SUPPLY PROCESS
Call (718) 939-3245 with your project type, the density or mix specification required, volume in cubic yards, site address, and delivery timeframe. If your project has engineered drawings specifying lightweight concrete, those will include the required density and compressive strength. We batch to your specification and deliver with a batch ticket documenting the mix. We run 24/7 and will coordinate delivery timing around your pour schedule and site access conditions across the boroughs.
LIGHTWEIGHT CONCRETE SUPPLY COST IN FLUSHING
Lightweight aggregate mixes carry a different cost structure than standard concrete, reflecting the specialty aggregates used in the mix. Pricing depends on the density specified, PSI required, volume, and delivery location. We provide free estimates. Call (718) 939-3245 and we'll give you a clear number.
WHY CHOOSE US
55+ years in NYC's concrete industry, and both owners work as contractors in addition to running the supply operation. We understand what lightweight concrete needs to do in the field on elevated applications, and we batch every order to spec with the documentation your inspector requires. Contractors rely on us for consistent product, reliable delivery, and a team that answers the phone when the schedule changes.
FREQUENTLY ASKED QUESTIONS
-
Structural lightweight concrete typically weighs around 105 to 115 pounds per cubic foot, compared to 145 to 155 pounds per cubic foot for normal weight concrete. That reduction in dead load allows structural designers to reduce the size of supporting columns, footings, and other load-bearing elements, which is why it's specified for elevated applications.
-
Yes. Structural lightweight concrete is designed to meet the compressive strength specified on the project's engineered drawings, typically 3,000 PSI and above depending on the application. The reduction in weight comes from the lightweight aggregate used in the mix, not from compromising strength. Your drawings will specify the required PSI alongside the density requirement.
-
Common applications include elevated decks, topping slabs over structural concrete, composite floor systems on metal decking, parking structures, and multi-story building floor systems. It's also used in residential projects for radiant heat floor systems installed over wood-framed decking where standard concrete weight isn't appropriate.
-
It can require more care during placement and finishing. Lightweight aggregates can absorb water, which affects workability, and the mix tends to have a higher moisture content than standard concrete, which extends drying time. These are factors to account for in your pour plan. Our team can discuss mix characteristics when you call.
-
Pumping lightweight concrete is possible but requires attention to the mix design, particularly the moisture content of the aggregate. Pre-soaking lightweight aggregate before batching can help manage workability during pumping. Tell us your site access conditions and delivery method when you order and we'll account for them in the mix.
