2K reactive waterproofing - multifunctional waterproofing of buildings
Bitumen-free, flexible and highly resilient
The 2K reactive waterproofing from BITUTEC is a two-component, multifunctional building waterproofing. Tested in accordance with DIN EN 15814 and approved in accordance with DIN 18533, it combines the properties of flexible mineral sealing slurries (MDS) with those of bitumen thick coatings (PMBC). It is bitumen-free, fast-setting and offers reliable protection - even for water tanks up to 8 m deep.
