An elevated waterproof access floor system having subfloor channels or compartments for power lines, gas lines or the like is adapted such that it can be opened and subsequently resealed without destroying the waterproofing and without destroying its aesthetic appearance. A multiplicity of tiles are supported on a support grid, and a flooring sheet is supported on the tiles. Attachment means are provided to prevent lateral but non vertical movement of the flooring sheet with respect to the tiles so that the flooring sheet can be lifted off the tiles, but when the flooring sheet is supported on the tiles, no lateral slipping will occur. The flooring sheet is made of a heat resealable material, so that it can be cut away in sections, and the tiles therebelow lifted off, to provide access to subfloor compartments. The heat-resealable flooring sheet can be resealed after penetration, to yield flooring system in which waterproofing and aesthetic appearance are maintained even after penetration. A method of assembling such a waterproof elevated floor system includes laying the tiles on a support grid, applying an anti-adhesive coating to the tiles, placing an attachment element into recesses formed on the tiles, placing an adhesive substance on the top surface of the attachment elements, and placing a flooring sheet across the tiles such that the flooring sheet is bonded to the attachment element by the adhesive substance thereon.
