Floor drains for outdoor use

Reliable drainage for courtyards, car parks, gardens, cellars, terraces and external downpipes

Dallmer offers a broad spectrum of drains for outdoor use. From courtyard and car park drains that do not require frost-proof installation through to rainwater drains for external downpipes. The latter can be securely anchored in flooring or concrete and have odour barriers that are both frost-proof and protected against drying out. If the drainage point needs to be protected against backflow, Klenkmatik drains offer a reliable option: the mechanical Klenkmatik flap automatically opens when water flows. However, if the water is trying to flow back from the sewage system, the pressure of the water automatically closes the flap.

If there is no special waterproofing specification, the PRONTO trap insert is a quick and cost-effective solution as it is very easy to install: simply cut the pipe flush with the floor, insert trap - done! The PRONTO family includes the PRONTO Primus, whose mechanical odour barrier also effectively protects against sewer gases even when the drainage point has dried out.
