Alcadrain's terrace drainage channel gained the Design Plus Award at the International Trade Fair ISH 2023 in Frankfurt am Main, one of the world's most prestigious exhibitions of bathrooms, heating and installations. This year, more than 2,000 companies from 154 countries presented their product news. The jury was mainly impressed with the invisible solution of the terrace channel, which allows it to blend in with the surroundings.

Drainage channels are suitable along facades on roof and ground terraces, in stonework greenery or walkways. The drainage system is linear, with the possibility of connecting in the transverse and longitudinal direction.
