In-situ solidification/stabilization (ISS) is a proven way to manage contaminated or unstable soils without large-scale excavation. By mixing binders directly into the ground, ISS strengthens soils in place and eliminates the mobility of contaminants, making sites safer, more stable, and ready for redevelopment. LRI delivers ISS with the accuracy, equipment depth, and field controls needed for sensitive sites and strict regulatory standards. It’s one of the most effective ways to manage large volumes of impacted soil when traditional removal isn’t practical.
ISS delivers long-term results while minimizing disturbance — a major advantage for active facilities, waterfronts, tight urban parcels, and areas with limited access. When designed and implemented correctly, ISS helps project owners with:
Reducing permeability and lowering leachability preventing contaminants from migrating
Improve soil strength, often enabling future redevelopment
Minimizes hauling and disposal, reducing truck traffic and off-site disposal costs
Works efficiently within tight sites, waterfronts, and active facilities
ISS often shortens remediation timeframes and limits the impact on surrounding communities. It delivers long-term stability without constant maintenance or ongoing exposure risks.
LRI brings industry leading experience with ISS, supported by a fleet of specialized equipment and teams who do this work every day. We’ve self-performed over 500,000 CY of ISS on over 30 different projects throughout the Northeast.
All ISS work is performed using LRI’s owned and operated equipment, including:
Owning our fleet means predictable schedules, consistent performance, and no dependence on third parties.
