Pipe Penetration Sealing
What is Pipe Penetration Sealing?
Pipe penetration sealing restores watertight integrity where pipes pass through walls, vaults, tanks, or other structures. Using trenchless polymer injection, infiltration points are sealed internally and externally, preventing groundwater intrusion, soil erosion, and structural weakening.
Problems Solved
- Groundwater infiltration at pipe entry points
- Soil erosion around utility penetrations
- Cracking and leakage in wall or vault interfaces
- Risk of contamination entering pipelines or utilities
- Costly failures from untreated infiltration and voids
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 Pipe Penetration Sealing
Pipe penetration sealing with polymer injection provides long-lasting protection against leaks at pipe entry points. These trenchless solutions safeguard infrastructure, prevent soil erosion, and extend the life of below-grade structures.
Protect Utilities and Structures From Infiltration
- Seals leaks where pipes pass through walls or vaults
- Prevents infiltration and soil erosion at penetrations
- Provides trenchless waterproofing without excavation
- Extends service life of utilities and structures

How the Process Works
1
Investigation
Penetrations inspected for leaks, voids, or soil loss
2
Planning
Injection design tailored to wall thickness and soil conditions
3
Access

4
Injection
Expanding polymers seal voids and create watertight barriers
5
Monitoring
Placement tracked in real time to ensure complete sealing
6
Validation
Final inspection confirms restored water tight performance
