Is a watertight membrane indispensable?

Yes, because the Bioteich natural swimming pool needs to stay totally watertight in order to economise water as much as possible. This is why Bioteich uses a SIKA membrane which offers every guarantee of quality and durability (reinforced fibreglass membrane, no plasticizing agent, UV resistant, ecologically recyclable, chemically neutral, etc). Several different colours are possible.
