The precipitation water collecting at the bottom of a facade must be swiftly drained away from the building. This is achieved by installing line drainage systems. These prevent damage caused to the building by the accumulation of water. Possible options include both closed and open channel systems, such as DACHFIX channels. A facade drainage system should blend harmoniously with the facade architecture. Also important is the high-value appearance of the channels. For this reason, HAURATON also offers non-standard solutions to customers' individual requirements.
