WHY TRENCHLESS

Today a majority of cities are facing significant challenges in pipe infrastructure asset management.

A large part of the current infrastructure was built by previous generations and is at or nearing its end of life.

In the mean time the society has evolved in such a way that the socio-economic impact of public works in densely populated area’s is not longer tolerated and any hindrance must be strictly limited.

Breaking up a road in the city centre to replace a pipe is only considered as a last resort.

In the last few decades the industry has strongly invested in the development trenchless rehabilitation techniques (pipe bursting, U-liners, GVK panels, CIPP liners, SIPP lining, etc...) which have been adopted by city authorities and private companies to increase the life expectancy of their pipe infrastructure with the following benefits compared to cut and cover techniques:

	Environment: every meter excavation avoided has a tremendous positive impact on the environment
	Overall cost: significantly lower for trenchless rehabilitation
	Surface footprint: very limited which is mandatory for cities
	Project duration: much shorter, meaning the necessary downtime of the pipe is limited

Proud partner of IBB16® technology

IBB16® is a hybrid hose pipe relining (without bonding to the old pipe – class A as per ISO 11295) 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 pressurized pipes.

UV-method: the first layer is a rigid laminate of fiberglass and polyester resin and provides the structural strength of the system. The lining is prefabricated, drawn into the pipe, inflated and cured by UV light.

Inversion method: the second layer is a thin and flexible felt lining with a solid PE inner coating. The felt liner is impregnated with epoxy resin and installed via the inversion method, cured with steam. This layer gives a smooth and very high-quality finish.
