20 years of experience in waterproofing of joints using swellable waterproofing products
As soon as in 2001 we launched our MASTERSTOP bentonite swelling tapes as well as the self-adhesive swelling tape MASTERSTOP SK. For 20 years we have been producing the bentonite swelling tapes with unchanged formulation and using high-quality sodium bentonites only.
In 2012 we developed the FLOWSTOP high-pressure swelling tape as well as the MasterMastic PU swelling paste and started market introduction only one year later.
Our swelling tapes and further waterproofing products are distributed throughout Europe via a qualified dealer network.
