TDS-240 (or Top Down Silicate 240) is a two-component urea silicate grout that comprises a silicate and a modified polyisocyanate intended for strata consolidation, water control, and rock/cable bolt grouting.
This grout is designed to secure rock and cable bolts in tunnel and mine applications. It quickly develops a thixotropic characteristic that minimizes free flow but allows continuous, as well as interrupted, pumping overhead.
