Drainage of flat roofs is an essential element to remove rainwater and protect the roof against damage or deformation due to moisture. Dallmer products are intended for flat roofs with massive or light structures, single- or double-layer. The technical data of drainage solutions should always be assessed in relation to the parameters of the specific building. Flat roofs are broadly divided into non-usable roofs, to which access is permitted only for maintenance purposes, and utility roofs, adapted for use by people and vehicle traffic.
Roof drainage
In the case of existing buildings, regardless of the type of flat roof, renovation may be necessary. Renovating a flat roof is not only a labor-intensive project, but also time-consuming, especially when it is necessary to dismantle old roof drains. Dallmer 63 T renovation drains not only save a lot of time, but also provide a reliable, professional solution of the highest quality. The use of renovation drains is very simple: the old drains remain in place, while the renovation drains simply need to be "pressed" into the stubs of the old drains. Thanks to flexible lip seals, the new gullies are tight and provide effective protection against backflow. 63 T renovation drains are available in sizes DN 70 - DN 150 and are available in a version prepared for connection with bitumen felts and FPO-PP and PVC membranes, as well as a version with a detachable mounting ring for connecting polymer roofing membranes.

Main advantages of Dallmer renovation drains:
Easy assembly
The old roof drain remains in place, the new one is pressed into its spigot. The roofer only needs to know the diameter (the relevant dimension is the diameter of the old connection stub or sewer riser).
Reliable sealing
Flexible lip seals ensure strong fixation and even out the unevenness of the old drain. At the same time, they guarantee the necessary protection against backflow. An additional stainless steel ring in the 63 T DallBit model provides effective protection against wind loads and detachment of the roof covering from the drain.
Perfect fit
Both with and without thermal insulation, the renovation roof drain 63 T fits all standard stub pipes. The body of our 63 T renovation drain is so small that it easily fits into almost all old drains. It is perfect for thermal insulation with ribbon roofing, or for laying new ribbon roofing as part of renovation works.
Save time
Using a Dallmer renovation drain requires much less work than dismantling an old roof drain. Thanks to short installation times, the 63T renovation drain significantly reduces renovation costs.
