Stone Strong Systems

What Stone Strong Systems does

Stone Strong Systems (legal entity Stone Strong, LLC) is a privately held manufacturer of modular precast concrete retaining wall systems headquartered in Omaha, Nebraska. Founded in 2001, the company designs, engineers, and licenses the production of large-format precast blocks (ranging from 3 to 24 square feet per face and up to 6,000-12,650 lbs) distinguished by a hollow core architecture with integrated drainage, lift/alignment loops for rapid installation, and a stone infill locking system that eliminates mechanical tie-backs for gravity walls up to 22.5 feet. The product portfolio spans Gravity, MSE (Mechanically Stabilized Earth), and Hybrid wall systems, complemented by corner, top, cap, and dual-face blocks, plus six customizable architectural finish patterns (Chiseled Granite, Tennessee Foothills, Fractured Ledge, Exposed Aggregate, Potomac, Smooth Face). The system is the first modular block fully engineered both structurally and geotechnically, is HITEC-evaluated, and conforms to AASHTO, NCMA, and ASTM standards for DOT-specification use.

The company's commercial offering addresses shoreline protection, erosion control, bridge abutments, box culverts, highways, commercial developments, and residential landscaping. Documented projects include 80,000+ sq ft installations for the Foothills Parkway in the Great Smoky Mountains (reaching 70+ feet), a 51-foot-tall free-standing wall in Woburn, MA, a 33-foot EMAS system at Rutland Airport, an Amazon Fulfillment Centre retaining wall using 1,779 blocks, and a Waikato River Bridge project in New Zealand, with a 100-year design life claimed for shoreline applications.

Stone Strong earns revenue through a two-stream model: (1) licensing fees from qualified precast producers who become authorized manufacturers of its proprietary blocks, and (2) hardware sales of blocks and system components distributed through the licensed dealer network. Its primary go-to-market is channel-led, with 40+ licensed precast producers/dealers serving customers across 28+ US states, Canada, Australia, and New Zealand (notably excluding Mexico), supplemented by direct inquiries through the website, technical documentation, MasterSpec inclusion, and engineering support targeting DOTs, engineering firms, and government entities. Key strategic partners include ACI, NPCA, Thiele Geotech (geotechnical engineering), Delta (EAS), Elk River Machine Company (precast forms), Increte Systems and Custom Rock (architectural finishes). Headquarters house 501-1000 employees; ownership is independent with no disclosed institutional investors.

Core offering

Stone Strong Systems manufactures and licenses modular precast concrete retaining wall blocks and associated wall systems (Gravity, MSE, and Hybrid configurations) for engineered retaining wall applications. The company's blocks range from 3 to 24 square feet in face area and incorporate a proprietary hollow-core design with integrated drainage, lift/alignment loops, and stone-infill locking, supplied through a licensed precast producer / dealer network across the US, Canada, Australia, and New Zealand. Architectural finish patterns (Chiseled Granite, Tennessee Foothills, Fractured Ledge, Exposed Aggregate, Potomac, Smooth Face) and engineering support round out the offering for DOT, commercial, shoreline, and residential projects.

Product overview

Stone Strong Systems is a manufacturer of modular precast concrete retaining wall systems. The core product portfolio consists of multiple block types (24-44, 24-86, D150, 24-62, 6-44, 6-28, 3-44, Dual Face, and various corner/angle blocks) ranging from 3 to 24 square feet in face area, complemented by Top Blocks and Cap Blocks for wall termination. These blocks are offered with six architectural finish patterns: Chiseled Granite, Tennessee Foothills, Fractured Ledge, Exposed Aggregate, Potomac, and Smooth Face. The company provides three wall system types—Gravity Walls, MSE (Mechanically Stabilized Earth) Walls using geogrid/Paraweb, and Hybrid Walls—targeting applications including bridges, commercial projects, shorelines, residential, roadways, and box culverts.

Products and services

• Gravity Wall System Modular precast concrete retaining wall configuration in which large blocks rely on mass and geometry for stability without geogrid or mechanical tie-backs; used where foundations allow gravity design and where schedule or footprint constraints rule out cast-in-place.
• MSE (Mechanically Stabilized Earth) Wall System Reinforced retaining wall configuration incorporating geogrid or Paraweb strips within the engineered fill behind the Stone Strong face units for projects requiring wall heights beyond the practical gravity limit.
• Hybrid Wall System Combined gravity and reinforced approach for challenging projects that require both the mass stability of a gravity wall and the additional structural reinforcement of an MSE wall.
• 24-44 Retaining Wall Block Large-format precast concrete retaining wall block with 8' x 3' face and 44" width, weighing 6,000 lbs, engineered for fast crew-paced installation; contributes to the 1,500 sq ft per day installation rate.
• 24-86 Retaining Wall Block Heavy-duty block with 8' x 3' face and 86" width, weighing 7,600 lbs, designed for tall gravity walls capable of going vertical at 22.5 feet without tie-backs.
• D150 Block Assembly Multi-unit gravity wall assembly weighing 12,650 lbs with 3.26 CY of concrete, engineered to enable gravity walls built in excess of 35 feet.
• 24-44 Mass Extender Block Extended version of the 24-44 block at 56" width and 10,000 lbs, used in combination with the standard block for greater achievable gravity wall heights.

• Cap Block Wall-top finish block with 7" face, 32" width, and 96" length, weighing 1,800 lbs, used to terminate the top of a Stone Strong wall.
• Top Blocks (24 SF, 6-44, 6-28) Top cap blocks matching the 24 SF, 6-44, and 6-28 face units, with a recessed face that allows multiple finish options for clean wall termination.
• Corner and Angle Blocks Specialty blocks for creating inside and outside turns at 90° and 45° corners, enabling direction changes in retaining wall layouts.
• Chiseled Granite Architectural Pattern Fully customizable chiseled-stone facade finish pattern matching a classic natural-stone look and developed from blocks hand-chiseled by artisans.
• Tennessee Foothills Architectural Pattern Sharp, well-defined finish pattern developed by laser-mapping actual retaining walls in the Great Smoky Mountains region.
• Fractured Ledge Architectural Pattern Highly-defined natural-look finish pattern created from actual fractured-ledge stone.
• Exposed Aggregate Architectural Pattern Hand-made pattern using exposed aggregate, with a unique design available for each block.
• Potomac Architectural Pattern Smooth and broken finish pattern replicating original cobblestone found in East Coast cities.
• Smooth Face Architectural Pattern Sleek, contemporary finish option providing a clean minimalist appearance for landscaping projects.
• Licensed Precast Producer Program Licensing/royalty program that authorizes qualified precast concrete producers to manufacture Stone Strong's proprietary retaining wall blocks, providing regional coverage, engineering support, and dedicated dealer portal access.
