A method and a system for punctual fastening a waterproofing and protective membrane (13) of plastic material, for protective and waterproofing surfaces of hydraulic works (10), such as canals, tunnels, dams and the like. In relation to surface areas subjected to fluid and/or wind actions, the protective membrane is fastened to the concrete structure (11) of the hydraulic work and/or to ground by a system of punctual fastening devices (15, 16). Each fastening device comprises an anchoring member to penetrate into the concrete structure and/or into ground (12) along a wished depth, provided with a tie rod or fastening end portion partially protruding from the surface to be covered, to which the protective membrane is sealingly fastened and pressed against the surface area of the hydraulic structure and/or ground by locking means. The locking means are conformed to provide a wide annular contact surface area with the membrane, suitable to transmit forces and/or strains to the punctual fastening devices.
