Q: As part of a dam repair project, we're installing grout curtains beneath the structure. On previous soil permeation projects, we've used sodium silicate as the grouting material. But we'd like to achieve a longer service life for the curtain and plan to use a cementitious grout. We've heard that ultrafine cements provide good performance for these applications. Who sells ultrafine cements?
