Karst Topography
What is Karst Topography?
Karst topography is a type of landscape formed in soluble rock such as limestone, dolomite, or gypsum. Over time, water erosion creates underground voids and sinkholes, which can undermine foundations, utilities, and infrastructure. Polymer injection stabilizes soils, fills voids, and provides long-term remediation in sinkhole-prone areas.
Problems Solved
- Sinkholes forming suddenly beneath structures and pavements
- Underground voids from dissolution of limestone or soluble rock
- Settlement damaging buildings, roadways, and utilities
- Groundwater infiltration eroding subsurface soils
- High costs and disruption from excavation-based sinkhole repair
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 Karst Topography Solutions
Karst remediation with polymer injection provides a trenchless solution to stabilize soils, fill voids, and protect infrastructure in regions with soluble rock formations. These solutions reduce risk, extend asset life, and prevent costly damage.
Reliable Remediation for Sinkhole-Prone Areas
- Fills voids and stabilizes sinkhole-prone soils
- Restores support beneath foundations and pavements
- Provides long-term trenchless remediation without excavation
- Reduces risk of collapse and costly infrastructure damage
