Posi-Shell™

Our Posi-Shell^® erosion control formulations give engineers and site managers the design flexibility to create highly effective, low-cost channel linings that address the challenges associated with concentrated water flows. Thousands of feet of highly durable lining can be installed per day with a crew of just 1-2 laborers. Unlike other lining systems, Posi-Shell^® is easy to maintain and integrates into the soil if a channel needs to be relocated or removed.

Posi-Shell^®’s simplicity and durability makes it tremendously effective at controlling windblown dust, infiltration, or runoff associated with clean or contaminated stockpiles. Unlike cumbersome tarps or geo-membranes, Posi-Shell^® erosion control coatings are spray-applied and do not require any ballast. Posi-Shell^® conforms and adheres to any topography and delivers clean runoff. Stockpile loading or removal is accomplished by breaking into the coating where desired. Active areas may be left open or quickly resealed if required. Posi-Shell^® erosion control coatings are ideal for protecting expensive piles of salt, coal, or cement clinker; furthermore, these coatings are used extensively for containing hazardous or radioactive soils.

When vegetation is not an option or the seeding season has passed, Posi-Shell^® erosion control coatings are the perfect low-cost solution to protect and stabilize slopes. Our long-term coatings are spray-applied and allow engineers or operators to protect acres (hectares) of slope in a single day. The finished coating is durable, as well as textured, therefore slowing water runoff. The final product eliminates erosion, siltation, and, as a result, expensive rework. The product can be designed to last for years with minimal maintenance and is easily tracked into slopes when intermediate protection is no longer necessary.

Delivered through any spray application equipment, LSC's suite of products and formulations offers engineers the flexibility to design new, or enhance existing, storm water pollution protection plans. LSC’s erosion control formulation (Posi-Shell^®), seeding product (EarthGuard Cube^®), and dust control product (Posi-Clear^®) are all versatile, low-cost, quick to apply, and meet the most stringent NPDES requirements.

Ash produced by wildfire often contains toxins that are potentially harmful to public health and the environment.  Prior to appropriate disposal, ash can easily migrate, by wind and rain, to adjacent neighborhoods, or deposit into sensitive waterways or ecosystems. Posi-Shell® is the most complete, effective and cost efficient “primary containment” product on the market.  Because Posi-Shell® is spray applied, hundreds of homes can be protected in a single day and workers remain clear of contaminants while coating.   Posi-Shell® does not impede regulatory testing or recovery of personal items making it popular with both regulators and home owners.  When the time comes for final remediation, the thin coating of Posi-Shell is simply taken away with the debris.  Posi-Shell remains effective for months to years, allowing for a safer and more systematic restoration of areas impacted by the wildfire.  LSC has a national network of installers that deliver unmatched response for virtually any scale of emergency.
