The trade group REWE has optimised its logistics network with a new central warehouse in Oranienburg, Germany ... and Dallmer drains are ensuring that everything flows smoothly on the roof of the huge new building.
When one of Germany's leading trade groups expands to improve the warehousing and delivery of its regional food markets, you know it's going to be big. In the space of just a few months, the company has erected a 52,000 m2 warehouse building on the site of the former military airport in Oranienburg: investment 60 million euros, workplaces for some 325 employees, supply of 330 markets between Sassnitz and Jüterbog.
Warehouses of this size also have very sophisticated demands in terms of building technology. As with all flat roofs, reliable drainage of the rainwater is essential, both under normal weather conditions and in the event of heavy rainfall. Heavy rainfall can very quickly cause structural problems with the roof construction.
During the construction of the huge warehouse building in Oranienburg, REWE opted for roof drains from Dallmer. Some 200 SuperDrain roof drains used with a siphonic roof drainage system were installed - hydraulically calculated by Dallmer using its proprietary DallPlan SuperDrain planning software.
Siphonic drainage is an extremely efficient system for both regular drainage and overflow drainage. Using this technology, the pipes are operated in a full state, which results in a significantly higher drainage rate than could be achieved with gravity drainage. A precise hydraulic calculation enables smaller dimensioning of the pipes, the laying of the pipes underneath the roof without the need for a slope and fewer downpipes and main pipes, thus saving material and labour.
SuperDrain drains from Dallmer can be combined with different pipe materials and are specially equipped for all roof membranes - made of bitumen, PVC, FPO-PE, FPO-PP and polymer sealing membranes. Excellent conditions for all kinds of roof projects
Overflow drainage units from Dallmer are the perfectly logical and cost-effective complement to its rainwater concept - as implemented at the REWE logistics centre in Oranienburg. Instantly identifiable as a separate system by their signal red colour, SuperDrain overflow drains are only activated in the event of large volumes of rainfall and a precisely calculated water over grate, when they immediately ensure reliable overflow drainage.
Perfect roof drainage on an optimised logistics centre - ensuring everything flows smoothly. From above as well as below.
