Boston Sand & Gravel

What Boston Sand & Gravel does

Boston Sand & Gravel Company is a privately held, vertically integrated construction materials supplier founded in 1914 and headquartered at 100 North Washington Street in Boston, Massachusetts. The company produces ready mixed concrete, aggregates (sand and crushed stone), interlocking concrete blocks made from recycled excess concrete, and a portfolio of LEED-qualifying "green" concrete products, serving residential, commercial, and infrastructure customers across eastern Massachusetts, MetroWest, southeastern Massachusetts and Cape Cod, and southern New Hampshire. Underlying production is supported by 5,600+ acres of controlled aggregate reserves in Hooksett and Ossipee, New Hampshire, a heavy industrial ready mix plant in Charlestown operated for over six decades, a database of more than 1,000 concrete mix designs including specialty formulations for winter concrete, slurry walls, and drilled shafts, and an owned Class III freight railroad (New Hampshire Northcoast, established 1986) that hauls aggregates year-round from Ossipee into the Boston market. Distribution combines a GPS-dispatched mixer truck fleet, the short-line railroad, a 12-acre marine/rail/truck terminal in Everett along Boston Harbor, and direct customer pickup at Charlestown.

The company operates through six wholly-owned operating subsidiaries — Southeastern Concrete Co. (southeastern Massachusetts), Manchester Sand & Gravel (Hooksett, NH), New Hampshire Northcoast Railroad, Rosenfeld Concrete Corp. (MetroWest, MA), Lawrence Ready Mix Concrete (southeastern Massachusetts and Cape Cod), and Ossipee Aggregates (Ossipee, NH) — plus a real estate entity (JMD Realty), giving it vertical control of reserves, production, rail haulage, marine logistics, and last-mile delivery across the region. Revenue is generated primarily through transactional one-time sales of ready mixed concrete (priced per cubic yard) and aggregates (priced by the ton), supplemented by transaction-fee rail freight services; no public pricing is disclosed and customers engage the sales team directly for quotes. The company has supported marquee projects including the Central Artery/Tunnel, Cambridge Crossing Parcel G (an 8,000-cubic-yard continuous pour completed in 13 hours on September 7, 2019), wastewater treatment plants, nuclear power plants, and various bridges and high-rise buildings, and holds LEED-accredited professionals on staff along with an NRMCA Environmental Product Declaration certification at the Charlestown plant (November 2019). Strategic supplier partnerships include BASF for admixture chemistry and rail interchange relationships with Pan Am Railways and CSX; the firm has not raised external capital and operates with 101–250 employees.

Products and services

• Standard Ready Mix Concrete Versatile ready mix concrete delivered in plastic state that can be placed by pumping, conveyor, buggie or chute and formed into any shape at strengths up to 14,000 psi. Used for cast-in-place building elements, sidewalks, airport runways, bridges, and parking lots by commercial and residential customers.
• Mass DOT-Approved Concrete Specialty concrete mix meeting Massachusetts Department of Transportation standards, engineered for long-term durability with low permeability to withstand freeze-thaw cycles and heavy salt use in New England winters. Used for bridge decks and intersections.
• Flowable Fill Concrete with very loose consistency resembling well-compacted soil, much weaker than conventional concrete and often required to be excavatable. Used for pre-trench for slurry wall applications, filling abandoned pipes and tanks, and backfill where soil compaction is impractical.
• Grout & Shotcrete Shotcrete (gunite or sprayed concrete) pneumatically projected via hose for high surface strength, plus grout pumped and placed via small-diameter pump hose. Used for masonry block fill, repair jobs, pump prime, and annular fill.
• Lightweight Concrete Concrete approximately 3/4 the weight of normal concrete due to expanded shale coarse aggregate. Appropriate for elevated floors in schools and hospitals, ballast applications in bridges, and building elements where weight and fire rating are important.
• Heavyweight Concrete Heavier weight concrete used for radiation shielding and ballast applications.
• Econo Fill LEED-qualifying flowable fill alternative made from conditioned fly ash, Portland cement and water, containing 100% post-industrial recycled content. Self-compacting and self-leveling, used for low-strength fill, non-structural below ground infill, irregular spaces, and restricted access areas. Qualifies for LEED MR-C4.1 and MR-C4.2 credits.
• Pervious Concrete LEED-qualifying eco-friendly pavement material with 15-25% void structure allowing 3-8 gallons per minute of stormwater to pass through. Prevents flooding, mitigates heat island effect, and can be produced with recycled materials. Qualifies for LEED SS-C6.1, SS-C7.1, MR-C4.1, and MR-C4.2 credits.
• White Concrete LEED-qualifying light-colored concrete effective in reducing heat island effect by increasing reflected sun energy. Uses white Portland cement producing the same end properties as gray Portland cement. Qualifies for LEED SS-C7.1 credit.
• Ready Mix Concrete with Recycled Fly Ash and Slag Mix designs replacing a portion of Portland cement with recycled cementitious products (fly ash from power plants, slag from steel production). Enhances pumpability and provides an environmentally acceptable alternative to landfill disposal.
• Aggregate (Sand & Stone) Sand and stone products including Coarse Concrete Sand, 3/8" Pea Stone, 3/4" Crushed Stone (angular), and 1 1/2" Crushed Stone (angular), sold by the ton. Produced from quarries in Hooksett, NH and Ossipee, NH and distributed by truck and rail.
• LEED-Qualifying Sand Products Sand products from the Ossipee, NH production facility transported by train to the Boston yard, qualifying for local material credits in the LEED rating system (LEED MR-C5.1 and MR-C5.2).
• Concrete Blocks Inter-locking blocks formed from recycled excess concrete. Available in 2' x 2' x 4' (~3,300 lbs) and 2' x 2' x 6' (~3,800 lbs) sizes from the Boston Sand & Gravel site in Charlestown, MA and Lawrence Ready Mix's Plympton, MA site. Used for retaining walls, containment structures, stabilization, and landscaping.
• Concrete Fibers (MasterFiber Series) Synthetic and microsynthetic fiber products including MasterFiber MAC 360 FF, MasterFiber F70, MasterFiber M 70, and MasterFiber M 100 for fiber-reinforced concrete meeting ASTM C 1116 standards.
• Colored Concrete Admixtures Color admixtures including Interstar NStar Non-Reactive Stain for concrete and Scofield Systems Chromix Admixtures for color-conditioned concrete.
• Concrete Admixtures Various admixtures including MasterMatrix UW 450 (anti-washout), MasterAir AE 200 (air-entraining), MasterGlenium 7500/7620 (water-reducing), MasterLife series (silica fume, waterproofing, corrosion-inhibiting, crack-reducing, shrinkage-reducing), Xypex waterproofing, and Krystol Internal Membrane.
• Class III Freight Rail Service (NH Northcoast Railroad) Class III freight railroad service hauling bulk goods such as steel and liquefied propane tanks. Rail service connects the Ossipee, NH aggregate facility to the Boston market and operates year-round including winter months.
