As an expert in sealing products, we know that a leakproof building entry starts with getting the "hole in the wall" right first time. It is for this reason that we have dedicated several decades to the development of innovative, high-quality and easy-to-use wall sleeves and flange constructions.
We can supply products for installation flush with shuttering, for setting in mortar and for retrofit dowel-fixing. Fixed/loose flange constructions provide a reliable means of integrating bitumen thick coatings or waterproof sheeting, the use of which is prescribed according to DIN 18195 Part 6 for protection against water penetration from the outside or seepage water.
Hauff-Technik’s empty conduits are the ideal solution for future-proofing buildings, allowing for the easy installation of cables and utility lines at any stage. Designed to be installed during the initial construction phase, these conduits provide essential pathways for utilities like power, fibre optics, and water lines. Whether you’re planning for future upgrades or retrofitting a system, Hauff-Technik’s range of empty conduits ensures seamless cable routing. Their products offer robust, gas- and watertight protection, providing long-lasting security for all types of utility installations.
Planning utility installations with empty conduits is a smart, long-term investment for any building project. These conduits create standardized entry points for utilities like water, power, telecom, and gas. Hauff-Technik offers a variety of empty conduits that can easily be paired with our sealing systems, ensuring professional, watertight, and gas-tight installations for cables of all sizes.
The adaptability of empty conduits is one of their key strengths. Once installed, they provide up to ten service lines through a single conduit, making it easy to add new utilities, such as fibre optics, without additional groundwork. These conduits are suitable for all types of structures, including waterproof concrete walls ("white tanks") and panel constructions.
By installing empty conduits today, you're not just preparing for current utility needs—you’re also ensuring your building is ready for future technological updates, saving on future planning and construction costs.
When it comes to creating cable entries, Hauff-Technik offers a broad selection of options tailored to meet various requirements. Their portfolio includes complete cable entry systems, essential accessories, and customizable empty conduits that can be utilized as needed.
For wall penetrations, Hauff-Technik provides cable entries in diameters of 90 mm and 150 mm. These entries come standard with pressure-tight closing cover, available in angled configurations and with either single or double sealing packs. This flexibility allows you to design a complete system that addresses most cable entry tasks effectively.
Furthermore, Hauff-Technik offers inner pipes (Futterrohre) in different materials, suitable for embedding during the construction process. Options for retrofitting are also available, ideal for situations that require modifications, such as wall breakthroughs.
In cases where existing utility lines are already in place and cannot be separated, Hauff-Technik's renovation pipes come into play. These two-part renovation pipes can easily be installed around existing cables, creating fully gas- and watertight cable entries with the appropriate seals.
Available in lengths from 70 mm to 1,200 mm, Hauff-Technik's empty conduits come in a wide range of diameters, starting from 40 mm up to 900 mm, making them suitable for various installation requirements.
Empty conduits serve as a reliable option for connecting utilities in buildings that lack basements. Typically, the cable entry process is vertical, with a 90-degree angle directed underground towards the street, where the utility line is introduced.
Cement composite pipes with sleeves are the preferred choice for this application. They provide durability and are both gas-tight and water-tight, allowing for direct embedding in the floor slab. The connection to the underground Hateflex spiral hose, which functions as the conduit path, is made using a robust EPDM sleeve. These pipes can accommodate various utility lines in the future. Once installed, the cement composite pipe is cut flush with the floor. Sealing for these empty conduits is effectively achieved with annular seals.
