Zara Logistic Center
The Zara Logistic Center in Zaragoza shows once again that the weight of single plies is one of their major characteristics. The membrane can weigh as much as 7 times less than some traditional multilayer waterproofing systems. The weight goes from 1.6 kg/qm up to 1.9 kg/qm, depending on the membrane thickness.
Initially, the architect planned to waterproof this building of 140,000 qm using so called "traditional waterproofing systems". This was immediately changed during specification into single plies when it was realized that this could save him over 840 tonnes in the roof build up.
