Installation steps: Pipe feed-throughs
Remove dirt from SOLITEX WELDANO 3000
using a cloth, for example.
Adhesion to frozen membranes is not possible.
There must be no water-repellent substances (e.g. grease or silicone) on the membranes.
Subsurfaces must be sufficiently dry and have sufficient load-bearing capacity.
2. Creating the bond
Guide WELDANO ROFLEX PLUS over the pipe.
3. Guide onto the subsurface
Place the grommet onto the subsurface
for bonding to SOLITEX WELDANO 3000,
ensuring that there are no folds in the
The resulting flange must point upwards.
4. Welding the grommet to the membrane
Weld the grommet around the edges using the WELDANO TURGA solvent welding agent or hot air.
The effective joint width (area covered with solvent welding agent) must be at least 3 cm (1 3/16") wide and must extend as far as the edge of WELDANO ROFLEX PLUS.
Use a roller to press the grommet in place.
5. Extending the flange
Prepare a sealing strip of SOLITEX WELDANO-S 3000 to suit the roof pitch and pipe diameter.
6. Attaching the flange extension
Attach the sealing strip of SOLITEX WELDANO-S 3000 to the pipe with a suitable adhesive tape.
7. Welding the flange extension in place
Guide the sealing strip around the pipe
and weld to one another and to the
sealing flange of the grommet using
Use a roller to press the bond in place.
8. Securing the flange extension
In addition, stick the sealing strip of SOLITEX WELDANO-S 3000 to the pipe and in the overlap area of the sealing strip using pro clima TESCON VANA.
