Drains
Prefabricated vertical drainpipe.
If you have a prefabricated vertical drainpipe, it is very easy and simple to install.
First, make a hole at the point where the drain is located.
Insert the prefabricated drainpipe into the hole.
Secure the drainpipe with spot welds.
Then, weld the inside part, applying hand pressure.
Weld the outside part, using the silicone roller and following the shape of the flashing.
Always weld from the inside out.
This will prevent the formation of air pockets and ensure a continuous weld
In the Vinitex range of accessories you will find drainpipes of various sizes
from which you can choose according to your needs.
Drains
Gargoyle
Place the gargoyle leaving the horizontal *** underneath the roofing membrane
Weld the membrane to the prefabricated gargoyle
Make a hole corresponding to the mouth of the drain on the membrane covering it.
Round off the corners.
Secure the membrane by spot-welding the base.
Weld the contour of the drainpipe mouth.
Then weld the coroners.
Finally,finish off the joints with the regular method.
Drains.
Manual vertical drain.
In the event that no prefabricated components are available for making the drain,
the process will require more time.
First, measure the drain to be treated
and cut a piece of non-reinforced membrane 1.5 millimeter thick.
make a cylinder from the cut piece and
insert it in the drain to determine the size.
Spot-weld the joint of the cylinder
and then weld it on the outside, without going all the way to the end.
This will allow the upper end of the cylinder to be stretched.
Turn the cylinder inside-out to work on the outside of it.
Now weld the joint on the other side.
Apply heat to the upper section until the membrane is malleable.
Stretch the membrane and shape it to fit the mouth of the drain.
Protective gloves are recommended for this operation.
Cut the points so they are curved.
Place the piece in the drain opening.
Spot-weld the piece to
secure it in the right position.
Continue to weld, running the roller along the shape of the drain until it is
completely sealed.
Take special care with the termination of the weld.
For added precaution, add another piece of membrane for reinforcement.
Cut the membrane into a ring shape, so that the inside diameter coincides with
the diameter of the hole.
Use 1.5 millimeter thick non-reinforced membrane.
Apply heat to the central part until the membrane is malleable.
Stretch and shape it slightly to fit it to the lip of the drain.
Put it in place.
Make a couple of spot welds
to secure the piece.
Weld of the inside of the drain, applying pressure with the roller.
Then continue welding from the inside out and in a circle.
Finally, weld to the outer diameter.
Prefabricated components are easier to use
and considerably reduce installation time.
