Ulma Architectural Solutions has installed its polymer concrete drainage channels in the surrounding area outside Hotel Vela, also known as Hotel W Barcelona. The five star hotel was given the moniker 'w hotel' due to its unique shape, and is located south of Barcelona port, close to the city.

Ulma provided its F range drainage channels, specifically the F250K channel with 2.5% presloped and ribbed cast-iron grate. The drainage solution with 2.5% presloped is the only system on the market with an actual slope of 2.5%. This pronounced slope increases water speed, maximises hydraulic capacity and means the channel can clean itself, thus reducing maintenance costs for municipal services.

This channel has been designed for heavy traffic areas, and is fitted with a grate which is attached to the channel using 4 screws per grate.
