Our versatile, market leading and innovative technologies are suitable for waterproofing all types of constructions including car parks, traffic decks, industrial sites, water management facilities for potable water and wastewater, pipes and belowground structures.

The construction industry benefits from our detailed knowledge of the corrosive environment in wastewater facilities, coupled with over a century of concrete repair and protection knowledge. This positions BASF to be the leader in water management solutions worldwide. Our superior technologies are strenuously tested to ensure adherence to local standards and high performance under local environmental conditions.
