PURPOSE: A waterproof material structure is provided for increasing durability and adhesiveness to outer wall and crack-resistant ability even at rapid variation of temperature to continue waterproof ability of the material, while inhibiting generation of the waterproof waste material. CONSTITUTION: The waterproof material structure comprises cement powder and crude rubber solution such as latex and water-resistant polymer resin such as acrylic resin or polyethylene resin or a mixture of them. The cement powder, water and crude rubber solution are mixed in a ratio of 2:3:1. The waterproof material is prepared by mixing and agitating cement powder and crude rubber solution; and blending it with further crude rubber solution and water-resistant polymer resin composed of the acrylic resin and polyethylene resin. |
