Solutions for Environmental Remediation Industries

Yes. Posi-Lock® can be used as an alternative to foam applications for many remediation and containment needs. Its spray-applied mineral-based membrane creates a durable barrier over contaminated soils and other exposed materials, providing effective containment while helping control dust, odors, and VOC emissions. Posi-Lock® can be used for temporary or longer-term containment, including during active excavation and other phases of remediation.

Posi-Lock® is a spray-applied, mineral-based mortar membrane that encapsulates contaminated material in place, protecting air, soil, and waterways from the toxic impacts of the site. It is used on Superfund and remediation projects worldwide to contain odors and VOCs during active excavation, prevent the migration of toxic dust and ash, encapsulate contaminated soils and stockpiles, eliminate toxic infiltration into groundwater, contain coal ash and asbestos, and establish debris containment following fires.

Durability is specified to the job rather than fixed. Formulations are available with service life measured in days, months, or years, in brown, grey, or green, so you balance longevity against cost for the project in front of you.

No. Posi-Lock® is easily accessed and patched where ongoing excavation is required, so the containment moves with the project instead of blocking it. Crews open a section, work it, and re-coat.

Application is straightforward: minimal surface prep, multiple acres per day, and it runs through LSC applicators such as the PCA-1000 or a standard hydroseeder. It can be applied remotely where safety or access is a concern, and it goes down year round in all conditions, so cold weather does not stall the schedule.

Odor-Armor® is a concentrated, multi-component blend of natural odor neutralizing compounds. Masking agents add to the overall odor intensity by introducing a stronger smell on top of the malodor. Odor-Armor® instead counteracts the odorous compounds directly, and the reaction is immediate and nonreversible.

Industry-specific formulations are matched to a delivery system that suits the site: high-pressure and mid-pressure misting, air and liquid atomization, direct injection, fans, and waterless vapor generation. Where water is restricted or temperatures drop, Vapor OPS™ produces a sub-micron waterless vapor through fixed diffusion points and will not freeze. For work that moves around a site, the Hydro OPS™ Portable Diffuser runs up to eight hours per fuel fill from a 275-gallon reservoir, covering 80 to 100 feet horizontally and 20 to 30 feet vertically.

Odor-Armor® is non-toxic, non-hazardous, and safe to use around people, animals, and plants.

AbsorbPRO™ is a high-performance solidification agent that converts liquid waste into a manageable solid, cutting both volume and disposal cost. It is designed for remediation sites, contaminated pond dredging, and general liquid waste management, and it lets material that would otherwise require liquid handling be transported and disposed of as a solid.

On the right project, substantially less. A power utility needed to establish vegetation on the outside berms of a 7-acre CCR basin. Doing it conventionally meant importing several hundred thousand cubic yards of soil, hundreds of hours of earthwork, and ongoing mowing to satisfy a regulatory limit that vegetation could not exceed six inches in height. That approach was estimated at $5 million.

Posi-Lock® was installed in a few weeks with the help of LSC's installation team and approved by the utility's local regulatory agency. It eliminated the soil import and the recurring maintenance obligation. Over 30 inches of rain fell within three weeks of installation, with another 60 inches over the course of the following year, and the coating remained in nearly perfect condition. The utility has since ordered additional acreage coated, and a nearby site is running the same program.
