Stormwater Rehabilitation
What is Stormwater Rehabilitation?
Stormwater rehabilitation restores the watertightness and stability of culverts, drains, and detention systems compromised by leaks, erosion, or settlement. Using trenchless polymer injection, voids are filled, infiltration is sealed, and soils are reinforced to extend the life of stormwater infrastructure.
Problems Solved
- Groundwater infiltration weakening stormwater structures
- Soil erosion creating voids beneath culverts and drains
- Settlement compromising stormwater basins and channels
- Cracking and displacement at joints or manholes
- High replacement costs for failing stormwater assets
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 Stormwater Rehabilitation
Stormwater rehabilitation with polymer injection seals infiltration, stabilizes soils, and restores watertight performance without excavation. These solutions reduce flooding risks, extend service life, and protect communities.
Extend the Life of Critical Drainage Assets
- Seals leaks in culverts, drains, and stormwater basins
- Stabilizes soils to prevent erosion and settlement
- Provides trenchless repair with minimal disruption
- Extends service life of stormwater infrastructure
