The present invention provides an excellent waterproofing sheet comprised of a self-adhesive soft first sheet having excellent elasticity and adhesion performance, a hard second sheet having excellent durability, and a third sheet made of a fiber material having weather resistance and impact resistance to protect the first sheet and the second sheet from external impact so as to efficiently deal with a behavior of a building by the softness of the first sheet, to secure a uniform waterproofing thickness using the third sheet made of the fiber material protecting the first sheet and the second sheet from external impact by maximized waterproofing performance due to the durability of the second sheet, and to be able to use the waterproofing sheet regardless of a wetting condition. The waterproofing sheet (100) includes a soft first sheet (110) self-adhered and fixed at a base surface (3) by self-adhesive force; a second sheet (120) integrated with an upper surface of the first sheet to secure excellent durability and maximize waterproofing performance; a third sheet (150) integrated with an upper surface of the second sheet (120) to prevent or protect the first sheet (110) and the second sheet (120) from being damaged by external impact; and a release paper (112) having a predetermined width formed at each of the both ends of a lower surface of the first sheet (110) to prevent self-adhesive force from being applied to the base surface (3). |
