METHOD OF PROTECTING TWO METAL PIPES AND A CABLE IN PE INSULATION PENETRATING FLOOR ACCORDING TO ETA-17/1061
1 - reinforced concrete floor with a thickness of B = min. 150 mm
2 - metal pipes with a diameter D1, D2 and a pipe wall thickness t1, t2
2a - plastic pipes with a diameter of D4, D5 and a pipe wall thickness of t3, t4
3 - Tubolit PE insulation on metal pipes, thickness "g" (continuous insulation)
4 - small cable, diameter D3, covered with PiroCoating on length L = min. 300 mm,
thickness a1 = min. 1.2 mm
5 - cable tie or adhesive tape
6 - Piro Multitube PM [h x s] mm band, placed inside the floor, at a distance of 15 ± 5 mm from the underside of the floor
7 - PiroCoat I on metal pipes with PE insulation, length L = min. 300 mm
and thickness g1 = min. 1.2 mm
8 - the space between the floor and the installation, filled cement mortar, approx. 25 mm.

Steps 1 - 6
Read in the table the length of Piro Multitube PM for the given diameter of the pipe, measure it and cut it with a knife.
Wrap the cut tape around the pipes and the cable. Follow strictly the number of wraps given in the table.
Secure the Piro Multitube PM with a cable tie or adhesive tape and slide it inside the partition. Location of the tape inside the opening - 15 ± 5 mm from the bottom of the floor.
Remove 300 mm of insulation from the pipes on both sides. By using a brush apply PiroCoat I on a pipe so that a ring with a width of min. 300 mm and a thickness of min. 1.2 mm is created.
Reattach previously removed insulation to the pipe on both sides of the partition.
By using a brush apply PiroCoating on the length of min. 300 mm. Fill the space between the bundle and the partition with cement mortar.
Mark the penetration seal with the attached label mark Piro Multitube PM, PiroCoat I, PiroCoating on it. Enter the date and name.
