Concrete Blocks Supply in Flushing, NY: CMU on Your Site When the Masons Are Ready
Your masons work at the pace your block shows up. Keep them stocked and keep the job moving.
🧱 Consistent Concrete Quality 🚚 On-Time Delivery 🤝 Supplier & Contractor Expertise 📍 Locally Owned & Operated
Concrete masonry units, called CMU or cinder block in the field, are the backbone of foundation walls, structural partitions, basement construction, and infill work across New York City. When block doesn't show up on schedule, masons wait and jobs slip. We deliver concrete blocks to job sites throughout Queens, Brooklyn, the Bronx, and Manhattan, on time, so your crew keeps working. Call (718) 939-3245 for a free estimate.
Any masonry project that calls for CMU needs a reliable source of block delivered to the site. Foundation walls on residential and commercial construction, basement walls, structural infill within a framed building, partition walls, and site walls are the most common applications throughout Flushing and the surrounding boroughs. The aging housing stock in the neighborhood, much of it built between the 1920s and 1960s, keeps steady demand for foundation repair and basement wall work that requires new block.
Running out of block mid-course, or waiting on a delayed delivery with masons standing around, is an avoidable problem. We coordinate delivery timing around your masonry schedule so the block is on site when the work requires it.

FREQUENTLY ASKED QUESTIONS
-
The most commonly used CMU in masonry construction is the 8x8x16 nominal block, which has actual dimensions of approximately 7⅝" x 7⅝" x 15⅝". The nominal size accounts for the standard 3/8-inch mortar joint. Other sizes including 4x8x16, 6x8x16, and 12x8x16 are available for non-structural partitions, fire-rated walls, and high-load applications. Tell us your project type and we'll confirm the right size.
-
Block quantity is calculated from your wall dimensions, accounting for the block size and bond pattern. A mason can calculate this from the project drawings, or you can estimate based on wall square footage. It's standard practice to order a small overage to account for cuts and waste. Call us with your dimensions and we'll help size the order.
-
Concrete masonry units come in lightweight (under 105 lbs per cubic foot), medium-weight, and normal-weight classifications. Lighter CMU is easier to handle and install, and tends to have better fire resistance. Standard-weight CMU has higher compressive strength. According to the Concrete Masonry and Hardscapes Association, all CMU used in construction must meet minimum requirements set by building codes regardless of composition. The right classification depends on your structural and fire-rating requirements.
-
Yes. CMU laid with rebar-reinforced and grout-filled hollow cores is a structural approach for retaining walls. For walls up to approximately four feet high, properly reinforced block wall construction is common. Taller walls or walls carrying significant surcharge loads require engineering. We can supply the block and advise on quantity for retaining wall applications.
-
Yes. We deliver throughout Queens, Brooklyn (except Coney Island), the Bronx, and Manhattan (except the West Side). Residential sites, narrow access, and urban delivery constraints are standard conditions for us. Tell us your site layout when you order and we'll plan the drop so it doesn't block access.
