GravityStone Edge is a commercial-grade retaining wall system developed by WestBlock Systems. It is a dry-stack concrete system that can be configured as a mechanically stabilized earth (MSE) wall, a multi-depth modular gravity wall, or a hybrid of both, depending on site conditions and design requirements.

GravityStone Edge is commonly used in commercial developments, residential developments, transportation and DOT projects, tight urban sites, and applications requiring transitions between modular gravity and reinforced wall sections.

GravityStone Edge walls can range from low-height gravity walls under four feet to large reinforced, multi-depth modular gravity walls or hybrid retaining walls exceeding 30 feet in height. Final wall height depends on site conditions, soil properties, loading, and project-specific engineering.

GravityStone Edge is currently manufactured by licensed concrete producers in Washington State and is distributed through Segmental Product NW. WestBlock Systems and local representatives can provide region-specific product and design support.

Yes. GravityStone Edge is designed to meet applicable ASTM and AASHTO standards and aligns with NCMA and CMHA segmental retaining wall best-practice guidelines. Project-specific designs should be prepared or reviewed by a licensed professional engineer.
