Grout Preparations at New Wales
The assembly of the onsite batch plant, where grout will be produced before being injected, is complete. Field trial mixes (test batches) are now being produced to ensure the grout mix meets specifications.
The initial phase of grouting will stabilize the base of the sinkhole’s upper cavity with concrete to fill any voids that may be present. The presence of a void otherwise could cause the piping that will be installed to deviate from its intended target. Stabilization will be done in stages, and should take approximately 20 to 30 days. Mosaic Fertilizer plans to start the stabilization phase next week.
