Sustainable, time-saving, flexible: The SAERTEX-LINER MULTI offers maximum efficiency when it comes to the trenchless rehabilitation of municipal wastewater pipes and pressure lines. The solution proven 90,000 times over: The GFR pipe liner couples performance with security and cost-efficiency. It is available in three construction variants.
- Type M: efficient performance for small nominal widths
- Type S+: best mechanical characteristics and interesting number of
- variants Type S+ XR: suitable for pressure lines up to 33 bar
The construction of the SAERTEX-LINER MULTI allows high pull-in forces and prevents the liner from overstretch. Its reduced weight makes for easy handling, the low wall thicknesses shorten curing times, and, in the "FastPlus" variant, the pipe liner saves even more installation time.
Technical service life of 100 years
Our permanent chemical- and corrosion-resistant ECR fiberglass produces unique constructions with multiaxial fabrics and a minimum long-term reduction factor after 20,000 hours (acc. To DIN EN 761).
Gliding and UV light protection foil
The gliding and UV light protection foil integrated as standard saves you the use of an additional gliding foil up to DN 600 and at max. 2.5 t liner weight. At no extra charge.
SAERTEX-LINER UPgreen: CO2-optimized
The climate-friendly manufacturing process for our UP resin systems saves an average of 250,000 kg CO2 per quarter. On request, we can provide you with a certificate showing the CO2 savings achieved by your projects.

Saves time and provides protection
This rugged inner foil remains inside the liner after curing and saves your team about 1h of installation time for every 100m liner. FastPlus also makes it easier to introduce the UV source, even in difficult installation conditions.
