Stabilizing pipelines and critical infrastructure?
Use rapid-support, closed-cell polyurethane systems designed for pipeline pads, pillows, and trench breaker applications.
Geotechnical
Pipelines, underground infrastructure, and concrete surfaces all rely on stable ground conditions. When soils shift or voids form, projects can face safety risk, schedule pressure, and expensive rework. Closed-cell rigid polyurethane geotechnical foams are engineered to fill voids, stabilize soil, support pipelines, and lift concrete with fast installation and long-term durability.
Rapid support and structural stabilization in shifting or compromised soils
Controlled expansion for precise void filling and lift accuracy
Consistent reaction profile for reliable, repeatable field performance
Long-term durability under moisture exposure and temperature variation
Proven and sustainable polyurethane systems for geotechnical.
FoamJack®
FoamJack™ is an expanding polyurethane foam system that lifts and levels concrete by filling voids and stabilizing underlying soil without excavation or replacement. Injected beneath slabs, it expands to restore settled surfaces and cures in minutes to minimize disruption. Suitable for driveways, sidewalks, patios, and foundation stabilization, it provides a fast, durable solution for concrete leveling.
Trench Break™
Trench Break™ is a closed-cell rigid polyurethane foam that expands to fill voids and stabilize soils around pipelines, foundations, and critical infrastructure. Lightweight and strong, it installs quickly with minimal disruption and reduces the need for extensive excavation. Used in energy, transportation, and municipal projects, it supports long-term ground stability and structural protection.
Polecrete® Stabilizer
Created with linemen in 1988 as a pole stabilization and backfill alternative, Polecrete Stabilizer® is the trusted name for Utility Line Pole Foam. It enables teams to set and secure miles of poles across any terrain. Eco-friendly, labor-efficient, and offered in different kit sizes to fit any job.
Engineered for ground stabilization and infrastructure support.
Contractors and infrastructure teams continue to prioritize safety, speed, and long-term performance across pipeline support, void filling, soil stabilization, and concrete lifting applications.
FSI provides polyurethane systems formulated for consistent expansion, predictable flow characteristics, and dependable in-situ performance.
