When pipe runs stretch thousands of feet or involve large-diameter infrastructure, traditional flowable fill simply isn’t enough. CGPS INC offers a smarter, more efficient solution: Stable Air™-powered cellular concrete, also known as LD-CLSM (Low-Density Controlled Low Strength Material. Our proprietary mix is designed for:
Stable Air™ is the chemical backbone of our advanced cellular concrete technology. By replacing heavy fine aggregates with engineered air content, we deliver a flowable fill that isn’t off-the-shelf ready-mix, it’s precision-engineered abandonment grout for real-world infrastructure decommissioning.
✅ 75% Air by Volume
✅ Pumpable Over 1 Mile
✅ Supports 6″-96″ Diameter Pipes
✅ Onsite Production at 200 CY/hour
✅ Lightweight and easy to pump
✅ Ideal for long pipe runs
✅ Diameter Pipes Versatile across infrastructure types
✅ Fast, scalable deployment
Most CLSM mixes rely on sand, cement, and fly ash, making them:
Heavy and hard to pump Prone to segregation over long distances Suitable for trench backfill, but not for pipe abandonment
Stable Air™ cellular concrete changes the game:
✅ Replaces aggregate with preformed foam
✅ Reduces pumping energy dramatically
✅ Flows easily through long, narrow, or complex pipe networks
CGPS INC routinely achieves:
Our mobile batch plants and expert crews make it possible—safely, efficiently, and at scale.
Whether you decommissioning stormwater, sewer, or industrial pipelines, CGPS delivers the best flowable fill solution
on the market with project locations nationwide.
