DURAGROUT is a ready-mixed, non-shrink, non-metallic, flowable, high-strength structural grout. It contains a balanced blend of washed and graded silica sands, portland cement, flow improving compounds, and a shrinkage compensating system which produces a volume stable structural grout. DURAGROUT produces high early and ultimate strengths without intermediate or latent shrinkage. It remains stable without failure from compressive loading, impact, lateral thrusts, high heat or continuous vibration. It is scientifically proportioned and is ready for use at varied consistencies from plastic to fluid.
