YOUR INTRODUCTION TO PIONEERING TECHNOLOGY
The procedure most frequently used in trenchless sewer rehabilitation is rehabilitation using pipe liners. Glass-fibre pipe liners have now achieved, since their introduction to the market in the nineties, a market share of approximately 70% compared to pipe liners made of polyester needle felt. As one of the leading manufacturers of glass-fibre pipe liners, iMPREG produces 300 kilometres of iMPREGLiner annually, which are used to rehabilitate defective waste water sewers around the world.
The advantages of rehabilitation using iMPREGLiner and UV curing are the excellent cost-effectiveness and the low social costs. The individual benefits are:
- The excellent speed of the process: Up to three pipes can be rehabilitated and put back into operation daily.
- The low amount of space required for the necessary equipment: Rehabilitation is even possible where there is little space, such as in urban areas.
- No notable impairments to traffic: With rehabilitation on public roads, the flow of traffic can continue to run virtually unimpaired.
- Happy residents: With rehabilitation in commercial or residential areas, residents are barely impaired by the work that only lasts a short while
- Trenchless technology: No digging is necessary, as a result of which there is hardly any dirt or noise generated and no damage to the environment.
- The excellent material properties: With the iMPREGLiner, you can achieve the highest static requirements with conventional wall thicknesses of a few millimeters. There are two types of liner available:GL01: the long-term elastic modulus is 7,300 N/mm², the long-term bending strength is 120 N/mm²
GL13: the long-term elastic modulus is 14,900 N/mm², the long-term bending strength is 200 N/mm²
The iMPREGLiner is currently produced in the dimensions DN 150 – DN 1600. With the rehabilitation of large dimensions using glass-fibre pipe liners in particular, you can benefit from the highest cost-effectiveness and a very quick installation time in comparison to other rehabilitation processes.
