LOCK+LOAD components are wet-cast from high-strength, air-entrained, reinforced concrete and simply lock together for easy construction.
LOCK+LOAD is a proven facing for any retaining structure: MSE, soil nail/anchor, H-pile or GRS walls.
Available in various formed finishes. LOCK+LOAD is formed in recycled plastic molds and provides guaranteed performance.

MMFX Steel Corp.
MMFX® Steel Corp. offers high-strength concrete reinforcing steels (ChrõmX®) with varying levels of corrosion resistance. Designers utilize the high-strength efficiencies and best match the corrosion protection requirements of the structure to meet the targeted service life.
Utilizing the high strength of ChrõmX rebar (Grades 100 and 120), designers reduce construction costs, shorten build times, resolve rebar congestion issues, enhance site safety and improve sustainability. Building codes and design guides supporting high-strength designs are available through the ACI, ICC and AASTHO.
ChrõmX rebar’s uncoated, corrosion resistance is derived from the steel’s chemistry and microstructure rather than relying on fragile coatings, resulting in a bar that can be handled and fabricated just like conventional rebar, without the risk of damage, repair or inspection problems.

RISAFoundation is the ultimate tool for analysis and design of a variety of different foundation types—all within an open modeling environment. RISAFoundation designs concrete and masonry retaining walls as well as two-way mat slabs, spread footings, grade beams, piles and pile caps. The addition of punching shear checks, rebar design, and international codes make it the smart choice for engineers.
Use the RISA Building System to automate the total building design. Start in RISAFloor to design the gravity system. Then take the model to RISA-3D for lateral design. RISAFoundation will finish the design by synchronizing the load transfer from the RISA-3D and RISAFloor models. Total building design has never been easier.
VERDURA® is a fully plantable retaining wall system that provides the strength and function of a standard retaining wall with the added ability to sustain live plantings. VERDURA® blocks are made of low-moisture-absorbing concrete that will not deteriorate over time.

StoneWall SELECT Retaining Wall System
StoneWall® SELECT® is a dry-stacked, segmental, modular concrete retaining wall system. Since StoneWall SELECT was introduced to the market in 1989, it has been successfully used in walls up to 40 feet high in level and surcharge conditions.
StoneWall SELECT employs the use of soil-reinforcing grids beginning at walls 36” and above for non-surcharge conditions and good soil, and it’s designed specifically to be used with soil-reinforcing grids. The granular fill in the cores, in combination with the interlocking clips, provides the connection between the grid and the units that is second to none.
StoneWall SELECT units meet or exceed the specifications for segmental retaining wall units, ASTM C 1372-97. These requirements assure a product of lasting durability, integrity and beauty.

Tensar’s® new Olympia® Retaining Wall System features a single block that can be set horizontally and vertically, creating limitless pattern options. This allows designers to create ashlar patterns, pilasters, stacked-bond borders or virtually any other pattern with just one block. Multiple colors allow rich aesthetics without the need for custom-sized small or vertical blocks. And each 0.89 SF Olympia block weighs approximately 65 pounds, making it one of the lightest systems per square foot. Lighter weight means less concrete to make, ship and place. Manufacturing efficiency, shipping efficiency, lighter weight and limitless aesthetic options with fewer blocks … that’s Olympia by Tensar. Contact Product Manager Steve Luptak and mention this ad for a free preliminary Olympia retaining wall design.
