We received an inquiry asking what grout would be best for a project that involves grouting 2" diameter ducts with 1" diameter Dywidag Bars, as shown in this photo.  The representative recommended US SPEC RA Grout, a high flow grout designed for rock anchor applications.  RA Grout is designed to provide maximum flow, shrinkage compensation and extended working times in an aggregate-free formulation.
