Services
Architectural CMU
Architectural CMU combines aesthetic appeal with structural integrity. Available in finishes like split face, ground face, and polished, these units expose natural aggregates for visual variety. Ideal for both structural and veneer applications, they offer design flexibility while meeting ASTM standards for durability and performance.
Insulated CMU
Insulated CMU integrates Korfil Hi-R inserts for superior energy efficiency. These pre-insulated units deliver tested R-values up to R-18, reducing heating and cooling costs. The system simplifies construction with factory-installed insulation, ensuring thermal performance without compromising structural strength or design versatility.
Acoustical CMU
Acoustical CMU, including Soundblox and Soundcell units, reduces noise pollution in high-traffic spaces. These blocks feature cavity-slot resonator designs that absorb sound without sacrificing compressive strength. Suitable for gymnasiums, mechanical rooms, and industrial settings, they provide durable, cost-effective noise control solutions.
Retaining Walls
Retaining walls combine structural stability with aesthetic appeal. Our Keystone systems, including Standard II/Compac II and Verazzo Stone, offer engineered solutions for erosion control and landscaping. These units ensure long-term durability while providing customizable finishes to match architectural requirements.
Ballast Blocks
Ballast blocks stabilize rooftop solar panel systems while withstanding freeze-thaw cycles. Available in multiple sizes, these normal-weight CMU units conform to ASTM C1884 standards. Their design ensures compatibility with racking systems, providing reliable support for renewable energy installations.
Questions
What types of concrete masonry units do you offer?
We offer architectural CMU (split face, ground face, polished), insulated CMU, acoustical CMU, retaining walls, and ballast blocks for diverse construction needs.
Are your products environmentally sustainable?
Yes. Our CarbonX technology reduces embodied carbon by up to 50%, and we source 70% of aggregates locally to minimize environmental impact.
Do you provide LEED-certified products?
Yes. We have third-party verified EPDs and HPDs compliant with LEED v4 standards for all mix designs.
What regions do you serve?
We serve New England, the New York Tri-State Area, and parts of Pennsylvania from our Central Massachusetts facility.
Can your CMU be used for soundproofing?
Yes. Our acoustical CMU, including Soundblox and Soundcell units, effectively absorbs noise in industrial and commercial settings.
How do insulated CMU improve energy efficiency?
Insulated CMU with Korfil Hi-R inserts provide tested R-values up to R-18, reducing energy consumption while maintaining structural integrity.
