Description of the Related Art Conventionally, as a waterproofing method for rooftops or the like, a concrete construction body surface is treated with a primer and then a urethane-based waterproofing material is directly applied and a finishing layer is applied thereon. There is a ventilation buffer construction method in which a nonwoven fabric or the like is provided between the membranes to provide a ventilation buffer layer. However, the former adhesion method, in which the waterproof coating film is adhered to the entire surface of the substrate, not only has insufficient followability for cracks and joint movement of the substrate, but also increases the temperature of moisture contained in the substrate. Thus, the waterproof layer has a disadvantage that a so-called blistering phenomenon occurs, in which the waterproof layer partially peels off from the base and partially swells. On the other hand, although the latter ventilation cushioning method is effective in preventing blisters due to the ventilation cushioning material, there is a problem in the workability such as a longer work time and a longer construction time than the close contact construction method.

For example, the unevenness may be a lattice shape, a honeycomb shape, or the like. It is not something to be done. The reason for this is that after constructing the sheet-like material for coating waterproofing work according to the present invention,
This is because the communication portion has a function of degassing water vapor caused by moisture contained in the base, and contributes to prevention of blistering.

When a swelling test according to SS-8 is performed, the swelling pressure is preferably 19.6 kPa or more. If the swelling pressure is less than 19.6 kPa, the intended deaeration function may be insufficient and the blister prevention function may be reduced. Factors controlling swelling pressure include:
There are at least the concavo-convex state of the portion to which the resin composition is applied and the area ratio or width of the applied portion, which embody the desired swelling pressure. The unevenness of at least the portion to which the resin composition is applied can be represented by the difference in height between the concave portion and the convex portion, and is preferably in the range of 1 to 500 μm. The area ratio of the resin applied portion is 1 to 30%, and the width of the resin applied portion is 3%.
mm or more is preferable. When the height difference between the uneven portions is less than 1 μm, the area ratio of the resin-applied portion is less than 1%, and the width of the resin-applied portion is less than 3 mm, the connecting force between the waterproof layer and the base is improved, but the degassing ability is reduced. Tend. On the other hand, the height difference of the uneven portion exceeds 500 μm, and the area ratio of the resin applied portion is 3
If it exceeds 0%, although the deaeration function is satisfactory, the force for connecting the waterproof layer and the base is insufficient, and there is a tendency to cause problems such as deformation and displacement of the sheet-like material for waterproof coating work. . The method of applying the resin composition and other materials to the sheet-like material is not limited as long as it can be applied industrially, such as coating, impregnating, and laminating.
