Retaining Walls

For commercial projects, engineers and designers need to have confidence in the Segmental Retaining Wall (SRW) system they are specifying; confidence in its structural integrity, manufacturing quality, and long-term performance. The Unilock Segmental retaining wall portfolio is specifically engineered to provide this assurance. With installations more than 25 years old, we offer the most proven SRW systems on the market.

For a product to be specified, it must meet and preferably exceed industry benchmarks. Unilock meets this requirement by manufacturing all SRW units to meet or surpass American Society of Testing and Materials (ASTM) specifications. Our systems also surpass the demanding National Concrete Masonry Association (NCMA) recommendations for Zone 3 applications: the classification covering structures exposed to de-icing salts and severe weathering. This dedication to exceeding technical standards provides commercial specifiers with the highest level of assurance that the structure will maintain its performance and aesthetic integrity.

Unilock structural wall systems are engineered to manage significant lateral earth pressure and stabilize critical grade changes. Whether utilizing high-mass gravity units or wall units combined with geogrid-reinforced soil masses, our systems are designed to perform. Primary applications of our SRW systems include:

• Creating Usable Acreage: Turning challenging topography into flat, developable land for buildings, parking lots, loading docks or other public and private infrastructure.
• Tiered Terracing: Turning a slope into terraced walls to manage global stability while creating space for pedestrian paths or softscapes between tiers, or for created amphitheatre style seating.
• Erosion Protection: Select Unilock wall products (ie. DuraHold) can be used for erosion control along streams, rivers, or lakes.

Unilock Segmental Retaining Wall systems are designed to support both functional and aesthetic goals across a wide range of commercial applications. With multiple unit sizes, textures, and color options available, designers can achieve clean linear walls, sweeping curves, or terraced grade transitions without compromising structural performance. This versatility allows our SRW systems to integrate seamlessly into site architecture, whether the objective is to complement surrounding buildings, define outdoor spaces, or create visually appealing landscape features. The flexibility of Unilock wall units empowers engineers and designers to respond to complex site geometries while maintaining design intent and consistency across large-scale projects.

Efficiency during construction is a critical factor in commercial projects, and Unilock SRW systems are engineered to streamline installation while delivering long-term performance. Larger wall units are compatible with mechanical installation methods, reducing labor time and improving jobsite productivity, while smaller units allow crews to work effectively in tight or restricted areas. Combined with proven durability and minimal maintenance requirements, these systems provide exceptional lifecycle value, helping project stakeholders manage costs while delivering retaining wall structures built to perform for decades.
