Wastewater entries

Wastewater Entries for Buildings with Basements

In underfloor buildings, connections to utility lines are typically made through wall penetrations. This method allows wastewater pipes and other utility lines to be routed horizontally through the masonry.

Hauff-Technik provides the perfect wastewater entry solutions for these scenarios. Our selection includes universal wall entries designed for double and element walls without a joint edge. These entries feature a sealing cap with a working flange and three three-stepped seals, making them compatible with wall constructions starting from a thickness of 240 mm. The universal wall entries are pre-assembled, blind-sealed, and suitable for flush installation. They are available in KG and KG 2000 quality, as well as sizes DN 100 and DN 150.

The universal wall entries from Hauff-Technik are optimized for flow, preventing changes in flow direction and backflow. This flow optimization also minimizes sediment buildup, significantly reducing maintenance needs.

After installation and concreting, Hauff-Technik’s wastewater entries are completely gas-tight and waterproof, ensuring that neither moisture nor radon can penetrate the building through the wall.

Tundishes for Embedding

Hauff-Technik offers tundishes as a practical solution for vertical wastewater penetrations, designed for direct embedding into the ground during construction. These funnel systems come equipped with an integrated level, ensuring accurate alignment throughout the installation process. The included adhesive flange simplifies the integration of a vapor barrier, which can be easily attached using adhesive film or bitumen welding.

This design enables a safe, trip-free installation due to the impact protection insert and complies with the requirements of DGUV 38 § 12a. Additionally, the tundishes feature an integrated three-stepped seal that guarantees a completely gas-tight and water-tight wastewater penetration. These funnels are specifically tailored for KG pipes with a diameter of 110 mm.

Wall Collars for Wastewater Entries in Slabs

Another effective solution for creating wastewater entries during the construction phase is the wall collar. This component is designed to fit directly over the wastewater pipe and is installed in place. Wall collars serve as a waterproof flange, ensuring gas-tight and waterproof entries into the building once they are concreted.

The KG-FIX series collars come equipped with two clamping bands, which cover a clamping range of 120 to 210 mm. This system is compatible with all standard smooth pipes, making it ideal for sealing drainage pipes.

Hauff-Technik also offers the KGF wall collar as a quick and tool-free installation option. Instead of traditional tightening clamping rings, the KGF system features TPE-profile double seals that are moistened and easily slid over the drainage pipe, allowing for rapid installation in just seconds. The KGF collars are available for media pipes with diameters of 110, 125, and 160 mm.

This innovative solution is pressure-tight up to 5.0 bar and offers comprehensive protection against radon infiltration. Additionally, a film sleeve can be incorporated to create a vapor barrier or radon protection, available as an accessory from Hauff-Technik.
