Tunneling Overview
KPI has more than 40 years of experience constructing water mains and storm and sanitary sewers through the use of, boring, tunneling and pneumatic hammer (piperamming) construction methods.
A leader in tunneling, KPI has pioneered a method of underwater retrieval of our remote-controlled tunnel-boring machines. We are experienced in constructing underground utilities in virtually every type of soil or rock formation.
We continue to perfect and advance our methods of construction, enabling us to work in all conditions.
