Concrete Blocks
Contractors and masons across Long Island and New York City come to 9 Brothers for concrete blocks that land the job right. We stock core building blocks for foundations, walls, chimneys, site work, and utility structures. Our Brentwood, East Setauket, and Riverhead yards are set up for fast loading, and we deliver across Long Island and NYC daily. We help homeowners too, but this page speaks your language. Pallet counts, lift access, tight streets, we get it. Tell us the scope, and we will match the block type, size, and accessory pieces so your crew keeps moving.
Types Of Concrete Blocks We Carry
Concrete Blocks, standard units in common sizes for structural walls and partitions.
Cesspool Block, perforated styles for drainage fields and on-site wastewater applications where approved.
Chimney Block, flue-ready units and throat pieces to build clean, plumb stacks and smoke chambers.
Block Vent, formed vents for crawl spaces and utility rooms that finish flush and allow airflow.
Need halfs, corners, bond beams, or lintel units. We carry those and can round out a full takeoff so you are not hunting for a single odd piece mid-pour. Real tip, confirm mortar type and reinforcement layout before you order, then add a few extra units for cuts and breakage so your last course is not short.
Brand Options
Cambridge, consistent sizing and dependable color for architectural faces where the block stays exposed.
Eldorado Stone and StoneCraft, veneer systems to pair with concrete block back-up walls for a finished stone look.
Delgado Stone and Dutch Quality Stone, natural and manufactured stone options that integrate well with CMU structures.
MSI, complementary trims and surfaces when the block is part of a broader finish package.
Techo-Bloc and Nicolock, hardscape components that interface cleanly with block retaining or seat walls.
Watsontown Brick and Glen-Gery, clay units and components when your CMU backup needs a brick veneer partner.
Tell us the finish you want, raw block, parged, stucco, or stone veneer, and we will point you to the right pairing.
Where Concrete Blocks Are Used
You will see our concrete blocks in foundation walls, elevator shafts, mechanical rooms, dumpster enclosures, knee walls, bulkheads, generator pads, and chimney chases. For site work, cesspool block and vents show up in drainage structures and crawl spaces. Homeowners use CMU for utility sheds and garden walls. Pro tip, keep cores clean as you build so grout and rebar place correctly, and stage pallets close to the lift path to cut steps for your laborers. Our customers ask for bond beam and lintel units on lintel runs, we stock them so you do not have to cut channels.
