Main Line Work

Toho Gas Techno lays or replaces new or existing under-road gas piping, using the main/branch trenchless method, which enables gas pipes to be installed underground with little need for road excavation, and other novel engineering methods developed in conjunction with Toho Gas Co., Ltd. to reduce the work period, carbon dioxide emissions and cost.
