ACO has always been a pioneer and has always set new standards. Now once again, the company has come up with a real sensa- tion in the channel sector: this channel, which comes with integrated Seal in technology included, load classes A–E and slope 1–10, brings together the very best features from 40 years of innova- tion – sealing as standard, easy to install as ever and with excellent performance. The unique combination of the ACO poly-mer concrete material on the one hand and sealing on the other creates the very first completely tight channel run that meets the demands of EN 1433. Lots of added value. The new standard of the future from ACO: ACO DRAIN® Multiline Seal in.
