In-house Rehabilitation

Rehabilitating the Building Drainage Without Dirt and Noise

Moist walls, musty odours and mould formation are common types of damage in buildings. The cause of this is often leaking waste water pipes, from which waste water leaks into the surrounding such as walls and ceilings as well as the building stock.

The rehabilitation of waste water pipes in buildings is subject to special regulations and strict structural engineering rules.

A particular challenge is created by high or fluctuating temperatures, as can occur, for example, in the kitchen or the washing machine area.

To make sure that the rehabilitation work is successful over the long term, the materials used must withstand the stresses and strains. In addition, for fire safety reasons all rehabilitation solutions for wastewater pipes in buildings must meet at least German building materials class B2 in accordance with DIN 4102-1.

 

The BRAWOLINER® HT rehabilitation system meets all structural engineering requirements and, what is more, have the demanding DIBt certification for the rehabilitation of waste water pipes inside buildings.

The Rehabilitation Solutions for Defective Pipes Inside Buildings up to DN 50

BRAWOLINER® HT was specially developed for in-house rehabilitation. This involves a high-tech textile hose, which is soaked with epoxy resin and then inserted into the defective pipe by means of air or water pressure. In doing so, BRAWOLINER® HT completely lines the pipe and thus eliminates all existing and also any potential damage.

The result is a completely new, watertight pipe in the old pipe with improved structural properties.

Complete Rehabilitation Without Uncovering The Pipes – This is How it is Done:

Just like going to see a doctor, the examination plays an important part before the rehabilitation of defective waste water pipes too. This is done with the aid of a special duct inspection camera. Before rehabilitation work starts, the camera images provide information about the state of the old pipe. The TV run shows fragments, cracks, bends and inlets so that the subsequent rehabilitation steps can be planned using the image material.

The old pipe is then cleaned by flushing it with water. Once the old pipe has been cleaned of all dirt and residue, the rehabilitation process can begin. A camera run also makes sense after the rehabilitation. In this way the success of the rehabilitation work is visually checked and verified.

Advantages of the BRAWOLINER® rehabilitation system:

  • Without excavation and chiselling work
  • Suitable for nearly all damage profiles and pipe materials
  • Much shorter rehabilitation times
  • Rooms remain inhabitable during rehabilitation
  • Environmentally friendly, sustainable and permanent
  • Lasts for over 50 years
  • Up to 50 % cheaper than open construction method
