Standard-compliant refurbishment with emergency drainage
Roof drainage renovation is often carried out with roof refurbishment and insulation in one operation.
In refurbishment it is nearly always essential to comply with the latest standards for roof drainage.
This means above all that calculating the drainage must correspond to the current (usually higher) rainfalls. The new systems then often need to be designed for higher performance.
And an additional drainage system, emergency drainage to the open, must also be retrofitted if it is not in place already!
There are two basic choices therefore in refurbishment:
1. With new parapet drainage
The "old" drain is decommissioned or dismantled and replaced with a new high-performance system.
If the fall on the roof is not already directed towards the parapet new sloped insulation is often installed.
Any additional costs due to the sloped insulation are quickly compensated because parapet drainage can be installed without pipes inside the buildings and operated with substantially less effort.
2. With renovation drain
If the existing pipework is still to be used LORO offers special refurbishment drains.
The LORO-X renovation drain has an extra-long connecting pipe with a specially developed sealing lip.
Depending on the width of the existing pipe, a smaller renovation drain width is used.
