Tunnel Repair Technologies

HEPA VACUUMES & FILTERSConcrete restoration of a tunnel can lead to waste and airborne particles that are the harmful to the environment and workers. Although not required, CMR uses HEPA vacuums and filters to maintain a clean and safe work site.
SHOTCRETE PUMP Shotcrete repair and installation is often an integral part of restoring a tunnel. The Thom-Katt trailer pump used by CMR is able to handle a wide variety of mixes and applications with powerful performance to provide a quality finished product.
VAPOR BLASTING CMR employs eco-friendly vapor blasting equipment to safely and effectively prepare surfaces and remove coatings at tunnel work sites. The vapor blast technology suppresses up to 97% of airborne particles.
ROBOTIC CHIPPING HAMMER Preparing a tunnel for repairs requires the dangerous work of overhead concrete chipping. For increased safety and consistency, as well as efficiency, CMR utilizes the latest technology of robotic chipping hammers.
