Combining powerful mixing capabilities, efficient material conveying, and a proven rotary gunite machine, this equipment provides a practical solution for tunnel repair, concrete rehabilitation, and industrial refractory applications.

What Is the Blastcrete Dampcon Rig?

The Blastcrete Dampcon Rig is a specialized shotcrete system designed to predampen and install dry-process shotcrete materials. Its integrated configuration includes a 9-cubic-foot paddle-style mixer with rubber wipers, a material elevator, and the reliable Blastcrete 020 Piccola rotary gunite machine featuring a single-bolt clamping system.

Designed with operator convenience and equipment reliability in mind, the Dampcon Rig offers simple operation, easy cleanup, and minimal maintenance requirements.

For contractors involved in tunnel rehabilitation and concrete restoration, this system provides an integrated approach to material preparation and shotcrete application.

Why Use a Shotcrete Machine for Tunnel Repair?

Tunnel structures are exposed to challenging conditions, including moisture, environmental deterioration, concrete cracking, and long-term structural wear. Shotcrete technology is widely used in tunnel rehabilitation because it allows concrete materials to be pneumatically applied to vertical, overhead, and irregular surfaces.

A suitable tunnel repair shotcrete machine can support several important applications:

Repairing deteriorated tunnel concrete surfaces.
Restoring damaged concrete linings.
Rehabilitating underground infrastructure.
Applying shotcrete to vertical and overhead areas.
Supporting concrete restoration and structural maintenance.
Installing refractory materials in industrial environments.

The Blastcrete Dampcon Rig is designed for dry-process shotcrete material preparation and gunning, making it a versatile equipment option for contractors handling specialized concrete repair projects.
