Waterproof execution of rubber sheet to wet concrete

Abstract

Abstract PURPOSE: To shorten the period of construction and reduce cost by adhering a waterproof sheet consisting of vulcanized rubber to wet concrete or cement mortar. CONSTITUTION: An epoxy resin added with a suitable quantity of a stiffening agent is applied on the surface of wet concrete or cement mortar. Next, while resin is not cured completely, an undercoating agent consisting mainly of a graft composition obtained from a monomer having natural rubber or synthetic rubber and a vinyl group is applied thereon. Then, a rubber adhesive is applied and then adhered onto an adhesive surface of the vulcanized rubber sheet and one side or both the sides of an epoxy resin finished by an undercoating agent.
