UNDERLAY CUSHIONING SHEET AND WATERPROOF STRUCTURE
Provided is an underlay cushioning sheet that is arranged on the surface of a foundation and that has a waterproof coating film formed thereon. The underlay cushioning sheet is provided with a cushioning layer having an overlay surface and a curing acceleration layer having a coating film formation surface on the opposite side from the overlay surface. A waterproof coating film comprising a polyurethane resin is formed on the coating film formation surface of the curing acceleration layer by applying a one pack-type liquid waterproofing material. The curing acceleration layer comprises a reactive material that is capable of reacting with the liquid waterproofing material. The reactive material either (1) comprises a functional group that is capable of reacting with an isocyanate included in the liquid waterproofing material or (2) reacts with a latent curing agent included in the liquid waterproofing material and generates a functional group that is capable of reacting with the components of the liquid waterproofing material.
