The sealing collar for waterproofing of pipes and conduits in water-impermeable buildings
The demands on water-impermeable concrete structures are regulated by the corresponding DAfStb guideline (WU guideline). In addition to requirements regarding the concrete structure itself, demands on the joint sealing and formwork ties or formwork tie points are defined here. The subject of this guideline is the corresponding planning and execution of the structure in order to meet the usage properties and usage requirements specified by the client with regard to the sealing function against water.
An issue not considered in the guideline, but not to be neglected for the result of a water-impermeable structure, is the waterproofing of pipes and ducts that are led through the concrete component. With our sealing collar, we offer the right solution for almost every installation situation.
