A new chemical grouting material, developed by employing the study result of an additive YDS which can activate the inert diluent , is introduced in the paper .It possesses very high permeability, strong affinity t o conventional media, excellent mechanical properties of consolidation and low cost price. It is suitable for strengthening low permeable ,soft foundation and concrete cracks' seepage control and reinforcement. Some illustrations are provided for explicating its practical usage effects.
