plantable concrete systems
Jan Jansson, Founder of Soil Retention, has been working in the Construction Industry since 1964! He started his career in carpentry school, Jan Jansson – Founder of Soil Retention then soon went on to earn an Engineering degree. Jan worked as a Superintendent and Assistant Project Manager for a major Swedish contractor for five years, then in 1969 started his own construction company in Sweden.
In 1987, after moving to America with his family, Jan opened a franchise in Riverside County, California to manufacture and distribute plantable retaining wall blocks.
Jan soon recognized the need to build a more durable, versatile and better plantable retaining wall block that would more effectively meet the needs of various market segments. After extensive research and development, Jan and the development team at Soil Retention created a new block called Verdura®, (“Verdant” for green and “Dura” for durable). Verdura® is a fully plantable retaining wall block system that can be used in many applications from small garden walls to large commercial structures.
The Verdura® retaining wall system was quickly recognized as the most versatile and strongest Mechanically Stabilized Earth (MSE) retaining wall in the industry, and is now Caltrans approved!
Soil Retention continued to grow and build a reputation for quality products and services. Soon two more products were added Drivable Grass® - a permeable, flexible and plantable concrete pavement system for fire lanes, access roads, driveways, parking lots, bioswales, ditches, and various post construction BMPs. Drivable Grass® can be installed on commercial or retail applications; and Enviroflex® – a tapered, vertically interlocking articulating concrete block (ACB) revetment system for channels, culvert outlets and wetland traffic crossings.
Drivable Grass® offers a simple and reliable solution to storm water management through biofiltration, infiltration, and storage without losing valuable site area. With the use of Drivable Grass®, storm drains, hydrodynamic separators, filtration devices, and detention basins can be reduced or eliminated. Drivable Grass® also counts for required green space allowing for more usable land while reducing Heat Island Effect.
"We are thrilled to offer customers another infill option that not only simplifies installation, but provides an effective permeable, drought tolerant solution that still looks fresh and green year round," says Nick Jansson, company VP.
Drivable Turf is available in two color variations (brown on green and green on green) through our distribution network.
The Verdura retaining wall system is designed with a "positive mechanical connection" between the block and the geosynthetic reinforcement. This mechanical connection provides a uniform distribution of tensional strength that does not rely solely upon frictional forces generated from a stack-height of the block-units or point load from pins or clips. Combined with the high shear strength from the lip of the block, Verdura allows for soil compaction directly behind the block units facilitating the use of heavy construction equipment within close proximity to the wall face. Larger walls are built concurrently with grading and backfill is placed with scrapers.
Enviroflex® offers a cost effective and environmentally friendly alternative to rip-rap, gabion mattresses, solid concrete or asphalt linings, and other hard armor systems. The thin profile of Enviroflex® requires less excavation, trucking, and handling compared to most traditional systems. Maintenance costs are also reduced by eliminating graffiti potential or pouring on more rocks after a major storm. The products ability to accept sediment infill from storm events allows the establishment of riparian plants and enables cyclical natural habitat while providing a stable and scour proof bottom.
