Lateral Joint Sealing
What is Lateral Joint Sealing?
Lateral joint sealing restores watertight integrity at the connection points where service laterals meet sewer mains or pipelines. Using trenchless polymer injection, leaks and infiltration pathways are sealed without excavation, protecting treatment plant capacity and extending pipeline service life.
Problems Solved
- Groundwater infiltration at lateral-to-main connections
- Storm water inflow overloading sewer systems
- Voids forming around leaking pipeline joints
- Increased wastewater treatment costs from diluted flow
- Risk of sewer backups and overflows during heavy rainfall
Types of Polymers Used
High-Density Polyurethane Foams
- Expands to densify and stabilize loose backfill soils
- Provides lightweight reinforcement without added soil pressure
- Cures rapidly to minimize operational disruption
Structural Polyurethane Resins
- Creates rigid reinforcement zones behind walls and utilities
- Transfers structural loads to stable ground layers
- Extends service life of supported structures
Hydro-Insensitive Polymers
- Expands and cures in wet or groundwater conditions
- Seals voids and prevents erosion in saturated soils
- Provides long-term durability in challenging sites
Benefits of Lateral Joint Sealing
Lateral joint sealing with polymer injection prevents inflow and infiltration at pipeline connections. These trenchless solutions extend asset life, reduce treatment costs, and protect system capacity.
Reliable Sealing for Sewer and Pipeline Connections
- Blocks infiltration at lateral-to-main connections
- Restores watertight performance in pipelines
- Provides trenchless sealing without excavation
- Reduces treatment and maintenance costs
