the fl oor area into a waste water collecting system. The specially
developed fl ange connector ensures absolutely leak-proof laying of
the channel run.

This high-quality and individual drainage system can be adapted
to suit your needs. Practically any height, width and load capacity
are possible. Stainless steel mesh gratings up to class C 250 are
available as covers.
