Featured Projects

• Project Location & Need: A new residential community in East Abbotsford required earth retention solutions to safely develop homes on steep hillside terrain while preserving natural beauty and drainage.

• Engineering Solution: Stone Strong Systems gravity walls were selected for their strength, modular design, and aesthetic appeal—essential for stabilizing slopes and supporting infrastructure.

• Collaborative Effort: The project was a joint effort between GeoWest Engineering, Citadel Properties Inc., and Langley Concrete Group, integrating engineering expertise with innovative precast solutions.

• Wall Design & Construction: The retaining wall spans ~15,750 sq. ft., constructed in five tiers using multiple Stone Strong block types and reinforced with geogrid in key areas—reaching over 9 meters in height and topped with fencing for safety.

• Performance & Efficiency: The contractor praised Stone Strong for its fast, easy installation, helping meet timelines while ensuring long-term stability and visual harmony with the surrounding environment.

• Impact: The project demonstrates how advanced retaining wall systems can unlock challenging hillside landscapes for sustainable, scenic residential development in growing communities.

• Wall Specifications: Free Standing 700-foot-long, 17,000 sq. ft. including over 850 precast blocks—most being the massive 24-86 units. Some wall sections reach up to 51 feet tall and are reinforced with concrete infill and vertical steel rebar for strength and safety.

  Unique Engineering: The L-shaped wall (334-foot West Wall and 362-foot North Wall) features a 4-inch setback per course to match the slope of the presplit rock face. Capstones with rock anchors provide additional stability.

  Site Safety & Construction Challenges: Extensive safety measures were required during footing construction, including trench boxes to protect workers from rockfall. 1,600 cubic yards of concrete were used for footings and block infill.

  On-Site Rock Processing: Roughly 450,000 cubic yards of granite were blasted on-site and processed through a complex mobile crushing and screening operation, producing a wide variety of materials for backfill and commercial sale.

  Wall Design & Construction: Manufactured by MBO Precast and constructed by Onyx Corporation in Woburn, MA, as part of a 12-acre development project is one of New England’s largest and tallest free-standing block walls.

• Massive Project Scope: Broccolini Construction was tasked with building Canada’s largest Amazon Fulfillment Centre—2.8 million sq. ft.—on a tight 14-month timeline.

• Critical Site Challenge: A retaining wall was needed to protect the facility’s parking lot from erosion due to a large berm near Highway 416, with limited space that ruled out tiebacks.

• Stone Strong Selected: Paterson Engineering recommended Stone Strong’s gravity wall system for its proven performance and ability to reach the required 8.7m height without tiebacks.

• Fast, Efficient Construction: R.W. Tomlinson completed the retaining wall build in just 4 months, aided by the simplicity and speed of Stone Strong installation.

• Custom Block Production: M CON Products manufactured 1,779 blocks—including 325 custom precast mass extenders in 4 depth variations—to accelerate construction during winter.

• Outcome: The Stone Strong system provided a durable, space-efficient, and timeline-friendly solution for a massive infrastructure project with strict constraints.

• Bridging the Scenic Gap: A 1.65-mile stretch completes the 72-mile Foothills Parkway, overcoming decades of stalled efforts due to extreme terrain, narrow corridors, and tight tolerances in the Great Smoky Mountains.

  Stone Strong Selected: Chosen for its structural strength, large block format, and natural stone aesthetics, Stone Strong precast walls provided a solution that met the National Park Service’s strict aesthetic and environmental demands.

  Massive Retaining Walls: The 14 retaining walls span 80,000+ ft² and reach over 70 feet tall—including double-tiered designs—all manufactured by C.R. Barger & Sons with a custom liner and integral coloring to match the mountain stone.

  Tight Tolerances, Seamless Install: Each block underwent 12-point QC checks and exceeded 4,000 PSI strength. Install crews praised the interlocking design, which ensured plumb walls and minimized risk on steep cliff edges.

  Construction Challenges & Innovation: Limited to 2' x 4' minimum block sizes, the team used laser scans to replicate nearby stone finishes, ensuring visual continuity between walls, bridges, and natural surroundings.

  Legacy Project: With five post-tension bridges, rugged roadwork, and a $48M scope, the project is a showcase of engineering and environmental stewardship—creating a lasting landmark for generations of hikers and travelers.

Stone Strong's small block makes a big impact on this residential home build. Stone Strong's smaller 6-28SF modular block became the big hero when the need for a tight radius wall arrived.

• Project Overview: Lynchburg College’s $12M student center expansion included building a substantial 20+ foot retaining wall to support a new roadway on steep, sloping terrain.

• Innovative Dual-Purpose Design: Instead of a typical wall, the project team created a unique retaining wall that doubles as a rock climbing wall — a first-of-its-kind feature on campus.

• Stone Strong Systems Chosen: The large-format, visually striking Stone Strong precast blocks met structural and aesthetic needs, delivering the “wow” factor Lynchburg desired.

• Complex Wall Composition: The design combined three walls — one steel-reinforced geogrid wall and two gravity walls — spanning 12,500 square feet and reaching heights over 24 feet.

• Efficient Production & Installation: Blocks production started early in February 2013; construction began in April, overcoming weather delays to complete the wall in just four months.

• Student Experience Enhanced: After construction, local climbing professionals outfitted the wall with climbing fixtures and safety gear, providing students with an exciting on-campus recreational amenity.

When a regional hospital needed to upgrade their parking lot space, including terraced parking, stairs and pedestrian access to different tiers, a large block modular wall system was the first choice. When a stream needed rerouted for the project without using any mechanical tie back, Stone Strong Systems was the first choice.

The City of Portland was in need of an asthetically pleasing retaining wall system that could not only provide a 9 foot tall gravity wall but also have fencing through the top portion of the wall. Stone Strong was able to accomplish both goals efficiently.

Stone Strong Tennessee foohills Pattern leaves Developer and Muncipality satisfied enough with project to continue to uses Stone Strong exclusively for future projects.

While bidding to replace a corrugated steel pipe culvert creek crossing along Hwy 89 with precast box culvert and wing walls, Stone Strong dealer, M Con Pipe and Products decided to approach the consulting engineer about using Stone Strong in lieu of the specified waste concrete blocks. The result was a Stone Strong box culvert and wing wall, which were installed on time and on budget.

Dealing with a failed wall that was creating a safety hazard and keeping a critical transportation route closed, Midway Middle School used Stone Strong's big engineered retaining wall blocks to create a strong, sturdy precast wall that’s designed to withstand the test of time and elements.

Working with a tight schedule, a waterlogged jobsite, and its customer’s aesthetic requirements, HS Construction & Excavating finds the perfect solution in a wing wall constructed from Stone Strong modular blocks.
