Posi-Shell® is a patented blend of clay binders, reinforcing fibers, and polymers that, when mixed with water or leachate, produces a spray-applied mortar that dries in the form of a thin durable stucco. Regardless of the weather, Posi-Shell® adheres to any surface and is effective in wet and dry forms.

Posi-Shell®‘s unique properties enable the use of durability enhancers to achieve long-term coatings that remain erosion resilient for more than a year.

Posi-Shell® is packaged in 50 lb (22.7 kg) bags or 500 lb (226.8 kg) bulk sacks and mixing is accomplished using LSC Equipment or standard hydroseeding units.

Posi-Shell® is the most effective, versatile, and cost-efficient alternative daily cover (ADC) system on the market.

Nothing, including soil, can match Posi-Shell®‘s ability to exceed daily cover requirements for litter, vectors, scavenging, fire, and especially odors. The Posi-Shell® cover system also prevents leachate breakouts and dramatically improves landfill gas extraction by eliminating barriers left behind by soils or other ADC’s.

With over 20 years of success at both large and small landfills around the world, Posi-Shell® has the demonstrated ability to deliver game-changing savings in airspace and operations cost.

Posi-Shell®‘s unique physical properties enable the use of durability enhancers to achieve long-term coatings that are quick to apply, aesthetically pleasing, and highly resistant to erosion. While foundationally similar to daily cover, our intermediate cover is harder and typically thicker than our short-term Posi-Shell®coatings while still offering significant savings in airspace and operations cost when compared to standard 12″ soil applications.

Whether the need is for swale lining, slope protection, silt minimization, or final seeding, LSC has the right product to achieve long-term coatings that are quick to apply, aesthetically pleasing, and uniquely customizable to meet specific durability requirements.

The video below shows a leachate reduction rain cap on a large Mid-Atlantic landfill. The runoff shown is from a 0.5 inch (12.6 mm) rain event channeling from 9 acres (3.6 hectares) of cover.

Posi-Shell®‘s mineral foundation offers a natural filter uniquely effective at controlling landfill odors. No cover system, including soil or other ADC’s, comes close to the odor suppression performance of Posi-Shell®. Landfill managers around the world rely on Posi-Shell® to keep the peace with neighbors and regulators.

For challenging odors generated by sewage sludge, landfill excavations, or composting operations, our innovative Odor-Shell® product can be used independently or in conjunction with Posi-Shell®. Unlike systems that attempt to address airborne odors, Odor-Shell® is topically applied using three synergistic mechanisms of sealing, filtering, and neutralizing to kill odors before they become a problem.

he Posi-Shell® system gives landfill operators the flexibility to solve a wide range of operational emergencies. Over the past twenty years, Posi-Shell® has been used successfully to address liner breaches, offensive odors, forensic searches, hydrogen sulfide releases, landslides, landfill excavations, fires, and countless other emergencies. In several high-profile situations, landfill managers and regulators have cited Posi-Shell® as critical to quickly solving problems and avoiding fines or temporary closure.

LSC has two distinct products that address the unique challenges common to fly ash. For sites interested in long-term solutions for dust, leaching, and erosion, Posi-Shell® Environmental Coatings deliver a nearly impenetrable cover that lasts for years.

For sites only interested in dust control, our naturally-based product, Posi-Clear®, reduces fugitive dust by bonding surface fines into a durable, cohesive layer. Posi-Clear® is not a chloride which makes it environmentally friendly.

The high solids content of our Posi-Shell® coating is perfect for extinguishing “hot loads” or dealing with challenging internal landfill fires. Posi-Shell®‘s natural mineral foundation is intrinsically non-flammable and WILL NOT ignite even under direct and sustained exposure to a torch. Additionally, our PSA series of applicators is specifically designed for landfill topography and provides operational access that water trucks or fire departments simply cannot match.
