LOCK+LOAD is a unique patented retaining wall technology that is available through licensees worldwide.

The LOCK+LOAD modular cantilever design is independent as well as self-anchoring. A major factor is that it allows for consistent backfill compaction all the way to the wall face. Uniform adequate compaction is key for MSEW wall construction. Also, paving, fences and barriers can be constructed adjacent to the wall face.

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.

Soil Retention

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. Because of the high shear strength from the lip of the block, VERDURA® allows for soil compaction directly behind the blocks, facilitating the use of heavy construction equipment within close proximity to the wall face. VERDURA® applications include hillside development, bridge abutments, channel walls, detention basin walls, screen and sound walls.

Soil Retention has been manufacturing, designing and installing VERDURA® retaining walls throughout California for more than 25 years without a failure! VERDURA® is Caltrans approved up to 40 feet!

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.
