Pipe Entries
Wastewater entries are a vital link between your building structure and drainage system. Precision-engineered for maximum safety, high-performance sealing solutions reliably block gas and water ingress while securing various pipe materials and diameters. Safeguard your building envelope with durable, efficient protection built for both new builds and retrofits.
Tundish
AT110
Tundish with integrated step protection for setting in floor slab concrete for perfect sealing to the underground sewer pipe. Gastight and watertight connection to the floor slab using integrated 3-ribbed seal. Gastight and watertight connection to the KG pipe using TPE-seal. To compensate an offset (after concreting) between downpipe and floor drain in any direction.
Wall collar
KGF
Water barrier flange for pressure-tight connection of waste water pipes in floor slabs.
Wall collar
HMK
Water barrier flange for watertight connection of pipelines in floor slabs.
Universal wall entry
UDM
Optimised flow through the wall – prevents blockages and backflow in the drainage system. The special design allows standard KG (2000) pipes to be adapted to the wall thickness and converted into a wall penetration directly on site. Can also be supplied to the required wall thickness.
Compensating pipe seal
ADM
For fixing in front of core drills, openings or wall sleeves or in front of cut-outs in sheet metal housings. The waterproofing of the wall can easily be integrated due to the design of the product. The same product also seals the incoming pipe.
