LAYING TECHNOLOGY Art. 45
1 - Spreading of a coat of Primer on the bottom, by the hole.
2 - Spreading of a thin membrane piece, 50x50 cm., make it adhere to the bottom after heating it by torch. If, on the contrary, the waterproof mantle is composed of more layers, the drain shall be laid after the first layer and the piece is suppressed, make sure that the grade of the housing is 3°.
3 - Try the drain in the hole and, at the same time, mark the point to cut in relation to the thickness of the wall. The cutting of the pipe (shaft) shall be made in such a way that the lower part is 5 mm. longer than the higher one, in case this is used with curves art. 46 and 47. But if the drain is placed in the box art. 118, it shall be cut at 45° (see drawing A).
4 - By means of a torch, heat the “piece laid as point 2” (or the first layer) and make the drain flange adhere.
5 - Smear with liquefied paste “obtained from a piece of membrane heated with torch”, filling all the flange ribs.
6 - Spread the last layer of the waterproof finishing mantle. It is advisable to heat it well in the area of the drain flange and that it adheres to the whole surface.
7 - Before inserting the curve, pass a mastic cord suitable for rubber of the “Bostik 292” type by Boston. After having inserted the curves, make sure that the drain pipe is inserted in the four
tangs that are inside the curves. The curve can be inserted in the box (as at point 3).
8 - Insert the Leafgrate/Gravelgrate - art. 44.1.

SPECIFICATION art. 45
Supply and laying of drain of the ITALPROFILI type, with an angle of 90°, based on IGOM EE synthetic rubber with the following dimensions: shaft 425 mm. long, 65 mm. high, 100 mm. wide, the flange shall be knurled and flexible, provided with curves for the connection to downspouts with a Ø of 80 or 100 or/and a funnel box to downspouts, complete with Leafgrate/Gravelgrate.
