Concrete Segment Polyurethane Injection

By Chris on 09-24-2019

Leaking concrete segments are injected with polyurethane grout in a tunnel that was created by a tunnel boring machine. The grout used was Hyperflex, which is injected as a liquid. The liquid material reacts with moisture and creates a hydrophobic foam to stop the infiltration.
