Abstract: A system for connecting the waterproofing with a drain pipe in indoor wet areas, suitable for being used in a main part of a drain that is in turn equipped with a discoidal plane wherein and on which a waterproofing sheet is positioned and attached, which includes an adhesive sealing means interposed between the aforementioned discoidal plane of the main part and the waterproofing sheet and said waterproofing sheet thus being arranged on and pressing on the adhesive sealing means, and includes a secondary part and a securing ring, wherein the secondary part entails a connection and support for a grid, wherein the securing ring is arranged uniformly on the waterproofing sheet when said waterproofing sheet is pressing on the adhesive sealing means in turn arranged between the discoidal plane and the waterproofing sheet itself, both the secondary part and the securing ring being coupled and interlocked with each other.

Abstract: An adaptive device for connecting a waterproofing to a built-in shower drain, said built-in drain comprising a drain body mountable in a clamping ring, which comprises a body made up of an upper section and a lower section with a through hole, in parallel arrangement at different levels, the upper and lower sections joined together by means of a deformable intermediate section which is capable of folding by means of at least one fold line. This device provides a global constructive system for built-in showers, greater versatility and adaptability to different thicknesses and layers of materials which may be used in the construction of a shower.
