Advantages of trenchless rehabilitation

Why you should refurbish instead of replacing the pipe

IBB16 ®  

UV Cross section view total Liner with Inner Coating:

IBB16 ®

The leading method for trenchless pressure pipe rehabilitation

Less environmental pollution

Less process costs 

for disposal of soil, old pipe and transport

Faster implementation

Less traffic obstruction

 due to smaller excavation pit

Environmental Aspects

Potable water pipe DN 800, 150 m length

Soil volume to replace 

IBB16 72m 3 /   Dig and replace 2.700m 3

Old pipe disposal 

IBB16 0,29m 3 /   Dig and replace 7,35m 3

Truck loads 

Trenchless 3 /   Dig and replace 98

Construction time 

Trenchless 10 days /   Dig and replace 60 days

Replacement of Pavement 

IBB16 12m 3 /   Dig and replace 225m 3

Reduction of emissions of all greenhouse gases caused by construction machinery such as CO2, CO, NOx, TOC, and SOx, smoke and other particulates. 

Very significant for every meter converted from trench to trenchless methods!

About IBB16 ®

The IBB16® system is a hybrid hose pipe relining (without bonding with the old pipe) applicable for the rehabilitation of pressure pipes. 

The system combines two pipe liners with different properties to achieve the required criteria for the rehabilitation of a pressurized water pipe. 

The system combines the IBG UV + Steam systems to the system IBB16®. 

Where to use IBB16 ®

The system can be used in pressure pipes up to an operating pressure of 232 psi (16 bar). 

The minimum pipe diameter is: DN 150

The maximum pipe diameter is: DN 1600

System description IBB16 ®

The impregnation of the liner is performed at the liner factory. The installation of the liner takes place in one or more rehabilitation conduits defined by two or more pits or line openings.

The liner is pulled into the line using a pulley, typically with winch support and sliding protective foil, pulled onto packers and expanded using air pressure.

Curing is performed by exposure from a UV light source. The entire curing process is controlled and documented using installed sensors.

The finished product is a statically fully structural, seamless, flexible plastic pipe.

Process steps for the application of the IBB16 ®

1. Cleaning

High-pressure cleaning of the pipe to be rehabilitated

2. Inspection 

Pipe inspection by robot inspection - Search for root ingrowths or similar

3. Milling 

Milling work to free the pipe from protruding hindrances

4. Second cleaning 

Second high-pressure cleaning of the pipe to be rehabilitated

5. Installation 

Installation of the UV liner including curing

6. Inversion 

Installation of the 2nd layer INVERSION - Steam curing Epoxy + PE coating

7. Final Pressure Test 

Final inspection and pressure test

Glass-Polyester resin Laminate - UV System

Epoxy resin layer - Steam curing

PE Inner-coating with felt layer
