The two-part system consisting of a custom-fit refurbishment plate.
- The plate is centrically arranged over the existing rainwater outlet and flashed against the existing waterproofing without backflow.
- The drainage element itself is then simply inserted into the refurbishment plate.
- Flashing against the new waterproofing is carried out either with connecting flange and screw ring (refurbishment rainwater outlet 125) or with factory fitted connecting flange (refurbishment rainwater outlet 75, 110).
