Polymer Emulsion Grouting for Water Cutoff in Tunnel Structures
Seepage in underground structures is a common problem facing contractors and facility owners alike. Unwanted groundwater intrusion–which arises as a consequence of initial construction–can develop into a costly repair and a prolonged tunnel maintenance program. The objective of this study is to illustrate the technology, performance and material characteristics of polymer emulsion and how it has been successfully applied to the problem of tunnel facility leakage. A regular grid of grout holes are drilled through the tunnel’s structural lining and polymer emulsion is pressure grouted into the annulus. The result is the formation of a dense, flexible barrier along the exterior of the underground structure which prevents water from entering the facility. Curtain grouting with polymer emulsion has been used in tunnel structures to provide a cost-effective solution for tunnel leakage with minimal impact to project schedules.
