KRASO Type LES - Light Shaft Drainage System for Concrete Shafts


The light shaft drainage system is just like our philosophy:
simple and tight.

Simple: just install KRASO Type LES - basis and KRASO Type LES - vario - connection in the waterproof (WU) building and connect it to the drainage.

Tight: your waterproof building is absolutely tight due to the thermally welded KRASO 4 Seal.

System: you are able to make additions or combinations according your requirements, e.g. odour stopper, sludge trap filter.
