    Tunnel Linings & Repair

    Shotcrete Structures was contracted to place 2 – 3″ of Shotcrete to re-align this tunnel previously constructed with Shotcrete using a Robotic Arm. It was discovered that the Robotic Arm did not provide the necessary quality control measures needed to accurately line the tunnel; therefore, the skills of a trained nozzlemen were used to corrected the thickness deficiencies. The Robots aren’t ready to replace us yet!
