A water shieldable material comprising a coating layer (2) having a specific density and comprising a specific rubber binder having non-watersolubility and flexibility and a high water absorption polymer particle (4) having a specific diameter and a solid substrate (3) supporting the coating layer, and at least satisfying the following conditions. 1. The density of the coating layer is between 0.65 g/cm3 and 1.00 g/cm3. 2. The weight ratio of the high water absorption polymer particle and the rubber group binder in the main portion, i.e., 90% or more by weight of the coating layer, is between 50% by weight and 90% by weight for the high water absorption polymer particle and between 10% by weight and 50% by weight. 3. The diameter of the particles belonging to the weight ratio of between 55% by weight and 95% by weight in the high water absorption polymer particle is between 45 .mu.m and 425 .mu.m.
