MODULAR EXPANSION JOINT

Introduction

TechStar’s Modular Expansion Joint System (MEJS) is an advanced solution for accommodating thermal expansion, contraction, and movement in bridge structures. Designed with precision engineering, our MEJS ensures smooth vehicle movement across large expansion joint openings while maintaining the structural integrity of bridges.

Modular Expansion Joint MEJ

Key Features

Smooth Traffic Flow
  • Divides large expansion openings into smaller, manageable cells to ensure a seamless driving experience.

Wide Movement Range
  • Ideal for bridges with expansion ranges exceeding 75 mm.

  • Handles complex movements, including longitudinal, transverse, and rotational adjustments.

Watertight Sealing
  • Equipped with watertight seals to prevent debris, water, and corrosive chemicals from damaging the bridge’s superstructure and substructure.

Durability and Load Bearing
  • Fatigue-resistant design for long-term performance under heavy traffic loads

Seismic Adaptability
  • Swiveling capability to absorb transverse and vertical movements during seismic events, ensuring resilience in high-risk earthquake zones.
