Inside The Legacy Of Charles H Gamarekian & Sons: Premium Hardscaping And Cambridge Pavers In 2026
Disambiguation Note: While historical business registries sometimes refer to "Charles H. Gamarekian & Sons" as an early foundational entity, this family enterprise is the direct corporate lineage behind Cambridge Pavers Inc., the legendary manufacturers of Cambridge interlocking concrete paving stones with ArmorTec.
The landscape of American manufacturing is defined by family legacies that transition from local craftsmanship into massive regional enterprises. In the hardscaping and masonry industries, few names carry as much technical authority as Charles H. Gamarekian and his sons. As the driving forces behind Cambridge Pavers Inc., headquartered in Lyndhurst, New Jersey, the Gamarekian family has spent decades redefining concrete paving technology across the northeastern United States.
Entering 2026, the demand for resilient, high-performance outdoor living spaces has reached unprecedented levels. Modern hardscaping must withstand extreme weather patterns, heavy vehicular loads, and chemical exposure while maintaining aesthetic appeal. Understanding the structural innovations introduced by the Gamarekian family—specifically their proprietary ArmorTec manufacturing process—provides landscape architects, civil engineers, and professional contractors with the criteria needed to specify durable, high-yield paving systems.
The Evolution of the Gamarekian Family Business
The story of Charles H. Gamarekian and his sons is rooted in a commitment to solving a fundamental structural flaw in standard concrete pavers: surface erosion. In the late 20th century, traditional concrete pavers quickly lost their color and exposed rough, unsightly stone aggregates due to foot traffic, vehicular wear, acid rain, and freeze-thaw cycles.
Recognizing this vulnerability, Charles H. Gamarekian Sr. established Cambridge Pavers Inc. in 1995 with a singular vision: to manufacture a maintenance-free paver that would look as vibrant decades later as it did on the day of installation. Working alongside his family, including his sons who stepped into executive and operational leadership roles, Gamarekian engineered a manufacturing shift that established the brand as a dominant force in the Mid-Atlantic and Northeast markets.
Operating out of state-of-the-art manufacturing facilities in South Amboy, New Jersey, the family enterprise has expanded its footprint in 2026 to service hundreds of authorized distributors across New Jersey, New York, Pennsylvania, Connecticut, and broader New England. Their operation relies on highly automated European manufacturing technology, combined with meticulous quality control protocols that meet and exceed both ASTM and Concrete Masonry & Hardscapes Association (CMHA) standards.
The Technical Science of ArmorTec: A Manufacturing Breakthrough
The hallmark of the Gamarekian legacy is the invention and refinement of the ArmorTec process. Standard concrete pavers are produced using a single-mix method, where a coarse aggregate mix of sand, gravel, cement, and pigment is compressed into a mold. Over time, the top layer of cement paste wears away, exposing the larger, aggregate stones underneath and causing the color to fade.
The ArmorTec process utilizes an advanced dual-layer manufacturing system:
- The Structural Base: The bottom portion of the paver is engineered with coarse aggregate and high-strength Portland cement. This provides the primary structural integrity, load-bearing capacity, and flexural strength of the paving unit.
- The Wear Layer (ArmorTec): The top layer of the paver is composed of extra-fine aggregate, rich color pigments, and a high concentration of premium cement. This layer is molecularly fused to the base during the high-pressure compaction and curing process.
This dual-layer engineering ensures that no large aggregates are ever exposed on the surface. As the paver ages, the ultra-dense, fine-particle top layer remains smooth, skid-resistant, and deeply saturated with color.
Material Performance Metrics
In 2026, municipal infrastructure projects and premium residential designs require rigorous verification of material performance. Every paver produced under the Gamarekian family brand is tested against stringent durability metrics:
Compressive Strength To comply with ASTM C936 standards, interlocking concrete pavers must exhibit a minimum compressive strength of 8,000 pounds per square inch (psi). Cambridge ArmorTec units consistently surpass this benchmark, frequently testing above 8,500 to 9,000 psi, making them highly resistant to heavy vehicular loads and pedestrian traffic.
Water Absorption Rates High water absorption is the primary cause of paver failure in cold climates. Water enters the pores of the concrete, freezes, expands, and causes spalling or cracking. While the ASTM limit is set at a maximum of 5% water absorption, the ArmorTec wear layer limits absorption to under 3%, significantly mitigating freeze-thaw damage.

Step-by-Step Installation Guide to CMHA Standards
Achieving the structural longevity promised by the Gamarekian family's engineering requires precise, industry-standard installation practices. The following guide outlines the execution workflow for installing a vehicular-rated driveway or premium patio using Cambridge ArmorTec pavers in 2026.
Step 1: Excavation and Subgrade Preparation
The longevity of any hardscape is determined by the preparation of the soil beneath it. Excavate the area to the depth required by the design load. For pedestrian patios, a depth of 6 to 8 inches is typical; for residential driveways, excavate 10 to 12 inches. Compact the subgrade soil using a mechanical plate compactor to achieve 95% Standard Proctor Density.
Step 2: Geotextile Membrane Installation
Lay a high-quality woven geotextile fabric directly over the compacted subgrade. This fabric prevents the migration of native soil particles upward into the gravel base while allowing water to drain downward, preserving the structural integrity of the base.
Step 3: Base Course Layering and Compaction
Spread a dense-graded aggregate base (typically 3/4-inch crushed stone with fines, often referred to as DGA or QA-2) in lifts of no more than 4 inches at a time. Moisten the aggregate slightly to facilitate optimal compaction. Run a heavy-duty vibratory plate compactor over each lift at least four times in alternating directions. The finished base must be perfectly flat and sloped at a minimum of 1.5% away from any building foundations to ensure proper water runoff.
Step 4: Bedding Sand Layer
Screed a uniform 1-inch layer of clean, washed concrete sand (conforming to ASTM C33) directly over the compacted aggregate base. Do not compact this sand layer before laying the pavers. This bedding sand acts as a uniform cushion that allows the pavers to bed evenly when compacted later.
Step 5: Placing the Pavers
Lay the Cambridge ArmorTec pavers in the designated pattern (e.g., Herringbone, Running Bond, or Random Modified Ashlar). Work outward from a 90-degree corner, keeping your feet on the already laid pavers to avoid disturbing the bedding sand. Use a rubber mallet to adjust minor alignments. Ensure a consistent joint spacing of 1/16 to 1/8 inch between units.
Step 6: Edge Restraint Installation
Install rigid structural edge restraints (industrial-grade plastic or aluminum edging) along all open perimeters. Secure these restraints with 10-inch steel spikes spaced every 12 inches to prevent lateral movement of the paving units under load.
Step 7: Compaction and Joint Sand Consolidation
Sweep a high-performance polymeric joint sand across the surface, filling all joints completely. Clean all excess sand from the surface of the pavers. Run a plate compactor equipped with a protective neoprene pad over the pavers to lock them into the bedding sand. Sweep additional polymeric sand into any joints that have settled, clean the surface thoroughly with a leaf blower, and lightly mist the surface with water according to the manufacturer's directions to activate the polymers.
Regional Distribution and Authorized Contractor Network
A major pillar of the operational strategy designed by Charles H. Gamarekian and his sons is the maintenance of a highly controlled, exclusive distribution network. Rather than selling through big-box retail home centers—where product handling, storage, and expert advice are often compromised—Cambridge Pavers are distributed solely through authorized masonry supply yards and professional hardscape distributors.
Northeast Regional Hubs and Availability
The regional footprint of Cambridge Pavers is concentrated in the Northeast, matching the areas most susceptible to severe winter freeze-thaw activity:
- New Jersey: Deeply serviced through local yards in Bergen, Monmouth, Ocean, and Morris counties, supplied directly from Lyndhurst and South Amboy.
- New York: Major distribution corridors across Long Island, Westchester County, and the Hudson Valley.
- Pennsylvania: High availability through eastern and central PA distribution hubs.
- New England: Dedicated distribution networks serving Connecticut, Massachusetts, and Rhode Island.
Contractor Certification and Quality Assurance
To prevent installation-related failures, the Gamarekian enterprise sponsors extensive contractor training clinics. Homeowners and commercial developers are strongly advised to hire certified professionals who hold active CMHA credentials and have completed Cambridge-specific installation courses. This ensures that the product's lifetime warranty is protected by sound engineering and proper site prep.
Frequently Asked Questions
What is the relationship between Charles H. Gamarekian & Sons and Cambridge Pavers?
Charles H. Gamarekian Sr. is the founder, Chairman, and CEO of Cambridge Pavers Inc. His sons have actively worked within the family enterprise, helping to expand its manufacturing operations, supply logistics, and regional sales distribution. The phrase "Charles H. Gamarekian & Sons" represents the close-knit, family-owned foundation that drives the quality control and strategic direction of the Cambridge brand.
What makes ArmorTec technology different from standard concrete pavers?
ArmorTec is a dual-layer manufacturing process. The bottom layer of the paver is made of high-strength concrete for structural integrity, while the top wear layer is formulated with fine aggregates, rich pigments, and premium cement. This design ensures that the surface remains smooth, retains its color, and resists aggregate exposure over decades of use, unlike single-mix concrete pavers.
Can Cambridge pavers withstand harsh winter de-icing salts?
Yes. Thanks to the low water absorption rate (under 3%) of the ArmorTec surface layer, Cambridge pavers are exceptionally resistant to de-icing salts and chemical scaling. However, for maximum protection, users should apply calcium chloride or sodium chloride de-icers sparingly and avoid the use of ammonium nitrate or ammonium sulfate, which can chemically attack concrete.
Is a sealant required on Cambridge ArmorTec pavers?
No, a sealant is not structurally required on Cambridge ArmorTec pavers due to the dense, low-absorption properties of the top layer. However, if a property owner desires a "wet look" or wants additional protection against oil, grease, or organic stains (such as fallen leaves or berries), an authorized Cambridge concrete sealer can be applied after the pavers have completed their natural efflorescence cycle (typically one year post-installation).
