Pipeline Support & Pillows
What are Pipeline Support & Pillows?
Pipeline support and pillow systems provide stable bedding beneath buried utilities by filling voids and reinforcing soils with expanding polymers. These trenchless solutions deliver uniform load distribution, prevent sagging, and extend the service life of pipelines and conduits.
Problems They Solve
- Pipeline sagging caused by voids or soil erosion
- Uneven bedding leading to stress at joints and connections
- Settlement around buried utilities creating misalignment
- Loss of support in areas of groundwater migration or washout
- High maintenance costs from recurring pipeline failures
Types of Polymers Used
High-Density Polyurethane Foams
- Expands to form custom-shaped pillows beneath pipelines
- Provides lightweight bedding support without overloading soils
- Rapidly cures for immediate stabilization
Structural Polyurethane Resins
- Creates rigid bedding layers for long-term load distribution
- Transfers pipeline loads to stable surrounding soils
- Protects against sagging and joint displacement
Hydro-Insensitive Polymers
- Performs reliably in wet or saturated soil conditions
- Seals voids caused by groundwater movement
- Ensures stable, watertight bedding support
Benefits of Pipeline Support & Pillows
Pipeline support and pillows provide engineered bedding that prevents sagging, protects joints, and ensures long-term pipeline stability. These trenchless systems reduce maintenance costs and extend the service life of critical utilities.
Stable Support for Buried Utilities
- Provides uniform load distribution beneath pipelines
- Prevents sagging and misalignment at joints
- Rapid curing allows immediate return to service
- Durable support reduces long-term repair costs
Key Applications
Water Pipelines
Supports pressurized and gravity-fed water mains against settlement
Sewer & Stormwater Lines
Stabilizes bedding for large-diameter and municipal systems
Industrial Pipelines
Provides durable support for process and utility conduits
Energy Transmission Lines
Protects buried gas and fuel pipelines from sagging and joint stress
Utility Corridors
Stabilizes multiple lines in shared trenches or easements
Outfalls & Intake Lines
Supports pipelines installed in marine and coastal environments
Industries & Applications
Pipeline support and pillows are used wherever buried utilities require stable bedding and uniform load distribution. From municipal water systems to energy transmission corridors, these trenchless solutions protect pipelines and reduce long-term maintenance.
