STABILTRAK 101

STABILTRAK 101

High-Strength Two-Componaent Polyurethane Adhesive for Railway Ballast Stabilization

Overview
STABILTRAK 101 is a cutting-edge, two-component polyurethane adhesive designed to stabilize and reinforce railway embankments and ballast. Engineered for high mechanical performance, it ensures durable bonding of crushed stone, aggregates, and substructures — even under dry or slightly damp conditions. Its low viscosity and excellent substrate penetration allow for precise application and long-lasting results in challenging environments.

Key Applications

• Bonding and stabilizing railway ballast

• Strengthening subgrade layers under tracks

• Consolidating loose aggregates and crushed stone

• Ideal for dry or slightly moist soil conditions

Product Advantages

• High mechanical strength for long-lasting support

• Low viscosity for deep penetration into aggregates

• Adjustable curing time depending on site conditions

• Low flammability and closed-cell foam structure upon contact with moisture

• Rigid-elastic bonding: ensures balance between firmness and flexibility

• Fast application using dual-component spray systems

• Moisture-reactive expansion: improves gap filling and stability
