Abstract
A method for producing a waterbar, the method including steps of providing first and second sealing elements each including a carrier layer having upper and lower major surfaces and a filled polymeric layer covering at least a portion of the upper major surface of the carrier layer and bonding the lower major surface of the carrier layer of the first sealing element to at least a portion of the lower major surface of the carrier layer of the second sealing element.
Claims15
A method for producing a waterbar comprising steps of:
- I) providing first and second sealing elements each comprising a carrier layer comprising at least one polymer P1 and having upper and lower major surfaces and a functional layer covering at least a portion of the upper major surface of the carrier layer and
- II) bonding the first and second sealing element to each other such that their carrier layers become directly or indirectly connected to each other over at least parts of their opposing lower major surfaces,
- wherein the functional layer of the first and second sealing elements is operative to bond with a fresh cementitious composition casted against it and allowed to harden.
