High-speed waterproofing


Saflex OA is a multi-layer asphalt waterproofing solution for engineering constructions made from concrete.
When used to resurface a bridge deck, for example, it is applied at high speed so that the bridge can reopen quickly.
It is ideal for large-scale projects and jobs that have to be completed quickly to minimize shutdown time.
Saflex OA meets the specifications laid down in French national guidelines (fascicule 67 and STER 81).
