This paper describes how siliceous slurry coating which is applied on the surface of mortar substrate having the defects such as cracks or cold joints, densifies the structure of cracks or cold joints and improves watertightness of them. It was investigated by the three methods ; the S. E. M. observation of the crystal production in pore along a crack or a cold joint, the measurement of porosity and that of water permeability. Crystals were not produced inside the cracks, even though siliceous slurry was coated on the surface of a mortal substratum. As for cold joints, a lot of additional crystals such as calcium silicate hydrate and ettringite were produced along the cold joints. As a consequence, the pore volume was decreased and the water permeability reduced.
