The Water Protection Act obliges property owners to maintain functional drainage systems. Damaged drainage systems need timely and professional renovation to protect groundwater and soil from contamination. The building drainage system consists of the dirty and rainwater from the floor inlets and the risers in and on the building. Damage to the property drainage system can have very diverse reasons. Most of them are due to aging or wear. In some cases, improper installation is also to blame for defects and functional faults.
Cause big problems
- Waste water escapes through leaky pipes
- Entry of groundwater due to root ingrowth and body formation
The inlining process is particularly suitable for the rehabilitation of property drainage pipes, especially in the case of damage such as static and leakage problems and corrosion protection.
Areas of application for inlining processes
- Waste water, meteor water, cooling water, ventilation pipes
- Pipes with a nominal width of 50–800 mm
- Refurbishment of connection, floor, riser and ventilation lines (also Y and T lines)
Advantages of the inlining process
- Less time spent
- Inexpensive procedure
- No digging necessary
- Suitable for hard-to-reach places and tight spaces
- Refurbishment inside the pipe
- Stable and tight lines with a very long service life
Procedure for damage restoration
- Inventory of the piping system
- Checking the pipe sections and sleeves
- Localization of the damaged areas
- Possible disassembly of toilets or washbasins or selective openings (approx. 60 cm) required for the installation of the inliner
- Refurbishment of the pipes from the inside of the pipe
- Assembling a tube made of needle felt or glass to the length and diameter of the channel.
- The hose / liner impregnated with epoxy or polyester resin is drawn into the pipe system.
- Subsequent curing of the hose with steam, air or UV light.
- The result is a stable, firm inner pipe in the pipe or duct section
- Connection of the pipe ends or intermediate shafts to the old pipe system
- Side connections are milled out with robots and tightly integrated.
