We have to stay outside

The Problem
www.hauff-technik.de
Unsealed openings can cause water ingress…
www.hauff-technik.de
…which results in structural damage…
…on the building… …and the cables
www.hauff-technik.de
…downtime…
www.hauff-technik.de
…and short circuits (animal ingress).

Common ways to „seal“
wall penetrations
www.hauff-technik.de
1. Create a hole in the wall
www.hauff-technik.de
Interface gaps between duct or pipe and concrete…
…due to shrinkage during the setting
process or poorly compacted concrete…
www.hauff-technik.de
Interface gaps between duct/pipe and concrete…
…or due to no fixation of the sleeves in the formwork
www.hauff-technik.de
Ovality…
…due to a low or insufficient wall
thickness of the pipes and the ducts.
no possibility for using a standard
seal (increasing costs)

2. Seal the hole in the wall…
…with cement…
…mastic putty or resin…
…or expanding foam
www.hauff-technik.de
Problem: None of the materials seal the whole opening
The material won‘t get around all cables or pipes.

Individual press seals
www.hauff-technik.de
• Customized seal manufactured to customers requirements with millimetre accuracy
• Closed design for newly installed cables
• Split design for retrofit sealing for cables that are already installed
• Eccentric, split design for cables already installed and not positioned centrically
• Optional overlapping flange for difficult installation situations
• also available as blind plug for sealing of unused openings
No matter what shape or size – the individual HRD will provide the
right solution

The patented 3-phase reaction
2nd phase ~ swelling:
At around 280°C, the filler starts to expand by up to 40%.
The result: All feed-throughs and cavities are optimally sealed.
1st phase ~ bonding:
At around 130°C, the contents of the pillows start to bond together.
The result: The contents do not leak if the envelope is damaged.
3rd phase ~ hardening:
At around 800°C, a ceramic reaction causes the pillow filling to
harden into a solid block.
The result: High mechanical stability of the fire-barrier is secured.
