BASF presents new fire-resistant tail sealant for underground construction at World Tunnel Congress in Dubai
“Our core business is providing chemistry and service for efficient underground excavation activities. By using MasterRoc TSG 800, our customers can improve both safety and cost-efficiency at the same time,” explains Wolfgang Aldrian, Head of Global Technical Management Underground Construction at BASF.
A new soil conditioner with greater stability
MasterRoc SLF 50, a new generation soil conditioning agent, has been specially designed to improve performance through the control of the soil during tunnelling operations under challenging soil conditions. This soil conditioner creates a highly stable foam with superior half-life to maintain face pressure during operation and planned or unplanned stoppages. It can lessen power consumption through torque reduction, optimize soil extraction and can decrease wear to the cutterhead. MasterRoc SLF 50 was used successfully in one of the world’s largest diameter tunnels being built in Seattle.
