PURPOSE: A waterproof sheet having damage preventing projections for tunnel waterproofing construction is provided to improve constructability by minimizing the resistance between the uneven portions of a construction plane. CONSTITUTION: A waterproof sheet(100) having damage preventing projections for tunnel waterproofing construction comprises a sheet main body(110), damage prevention projections(120, 130), and a fixing member(140). The sheet is made of bendable materials. A plurality of damage prevention projections is formed at different height on one surface. Uneven portions formed irregularly are partially accommodated between the damage prevention projections. The damage prevention projections separate the sheet from the uneven portions. The fixing member is fixed on a construction plane and extended from one side of the sheet main body. |
