Landmark Earth Solutions Introduces New Erosion Control Technologies

Landmark Earth Solutions Inc. (LES) will unveil three new engineered erosion control and earth management technologies in Orlando, Fla., at Environmental Connection 2011, the International Erosion Control Assn.’s annual conference and exposition.

The new offerings include the EcoTrans transition mat; the Safe Slope Xtreme hydraulic mulch; and RIBS, a rapidly deployed emergency water and flood control system.

The newest offering in the transition mat category, EcoTrans is a 100% recycled vegetated replacement for rock rip rap, intended for applications in severe hydraulic conditions that do not require the premium attributes of ScourStop, LES’ flagship transition mat. EcoTrans’ structure provides more than 50% open area for dense vegetative establishment, and provides day one protection in extreme conditions with minimal required maintenance.

Applications for EcoTrans include culvert outfalls, overflow structures, stream banks, bridge drains and levee and shoreline protection. EcoTrans typically is used over a turf reinforcement mat and/or sod and anchored to the native topography of a site, protecting the areas with the highest hydraulic stress and scour potential, while other best management practice soil covers are used in downstream, lower stress areas.

Safe Slope Xtreme is a high-performance natural fiber hydraulically-applied mulch made from a proprietary blend of biodegradable cotton plant byproducts, crop residue and reclaimed cotton lint enhanced by unique bonding agents that enable all components to effectively interlock and adhere to the soil. The flexible, porous seal that results absorbs enough moisture to both reduce soil loss and facilitate seed growth without fertilization in hydroseeding applications on even the roughest terrains and steepest slopes.

Safe Slope Xtreme disperses into a homogeneous slurry and features a low water-to-mulch ratio (100 gal per 50 lb) that significantly reduces project installation costs.

RIBS is a rapidly deployed, patented alternative to sandbags for flood control and de-watering applications. With installation rates up to 30 times faster than standard barriers, RIBS’ trapezoidal design resists water flow while providing a stable barricade against severe weather events and the threat of encroaching waters.

Woven, reinforced polypropylene fabric bags 2, 4 and 6 ft in height are loaded with sand, dirt or gravel in a special trailer, which deploys as other bags are added and filled. RIBS can be used instead of sandbags in flood control, to restrict water flow and erosion on beaches and riverbeds, and for containment measures on construction and mining sites.
