We have gained valuable expertise in tunneling and underground infrastructure; in both design and construction for road and railways. The Design includes geotechnical investigation, geological assessment of strata, design of lining, drainage, water proofing, lighting, ventilation etc and the Construction phase includes, lay out, excavation as per alignment, supporting structures, muck transportation, grouting, rock bolting, shot-creting, guniting, lining and operation & Maintenance. We have designed structures for various soil & rock conditions. Some tunnels have also been designed to resist blast.

We have worked in various types of soil and rock condition with different types of excavation such as conventional tunnelling using drill and blast methods, Mechanical drilling/cutting, pipe jacking and shaft-raising plant etc.

CAPABILITIES

We have the capability for designing of road and railways tunnels and underground infrastructures for various soil & rock conditions and even blast resistant.

We have supervised Tunnel in sharp curves with precision surveying in various types of soil and rock condition. We have executed work with drill and blast methods, Mechanical drilling/cutting, pipe jacking and shaft-raising plant, Cut and Cover method etc.
