Case Studies and Site Solutions
Explore real-world GravityStone® retaining wall case studies that demonstrate how modular and hybrid systems solve complex site constraints. From tight urban sites to environmentally sensitive slopes, these projects highlight reduced excavation, faster installation, and long-term performance.

Alaska Street Widening
-
Product: GravityStone® Tradition
-
Challenge: Cut site to widen roadway, preserving the home at top of slope
-
Solution: GravityStone Hybrid MSE over Modular, reducing Excavation needs
The Villages
-
Product: GravityStone® Tradition
-
Challenge: Curved underground golf cart tunnels required vertical walls with no batter; pre-cast concrete couldn’t follow road radii or achieve the desired Old-World aesthetic.
-
Solution: GravityStone’s hybrid system delivered modular flexibility, true vertical construction, and a tumbled, time-worn finish.
Tomlinson Residence
-
Product: GravityStone® Tradition
-
Challenge: Steep hillside site with limited excavation near existing home footings
-
Solution: GravityStone Modular enabled curved walls with minimal excavation, creating a natural-looking entry feature within tight site limits
Pemberton Creek Estates
-
Product: GravityStone® Tradition
-
Challenge: 63 home community on steep slope site, high surcharges, and water considerations made the site hazardous
-
Solution: GravityStone Hybrid MSE over Modular, stabilizing foundation and increasing connection strength
San Mortiz
-
Product: GravityStone® Tradition
-
Challenge: Road widening on a steep hillside while maintaining access and protecting adjacent wetlands
-
Solution: GravityStone Modular delivered a tall, narrow retaining wall with minimal excavation, preserving access, environment, and budget
Master Park
-
Product: GravityStone® Edge
-
Challenge: Severe space constraints near SeaTac Airport with over 30 feet of grade change and heavy runoff
-
Solution: GravityStone Edge created tall, space-efficient walls with integrated drainage, minimizing excavation while keeping the facility fully operational
