Our SAERTEX-LINER INDUSTRY is a combination of vinyl ester (VE) and ECR fiberglass that gives it high media and temperature resistance. It is ideal for use in the trenchless rehabilitation of industrial wastewater pipes and we adapt our product to your application – based on the proven Type S+.

Resistant to high temps and corrosives

By combining the corrosion resistance of ECR fiberglass with the chemical resistance of vinyl ester (VE), SAERTEX-LINER® INDUSTRY is engineered to withstand the harsh effects of industrial wastewater. Since the liner’s high-resistance properties are dependent on the temperature and concentration of the chemicals, our product engineers will consult with you to determine if it is suitable for your application.

Installation-friendly and time-saving

Low wall thicknesses shorten curing times, and the reduced weight of the liner optimizes handling. The liner’s construction allows higher pulling forces and prevents it from overstretching. The optional “FastPlus” inner foil remains in the liner after curing, saving time.

Technical service life of 100 years

Our unique ECR fiberglass reinforcement is based on multiaxial fabric technology that withstands high mechanical stresses. SAERTEX-LINER® INDUSTRY offers the same excellent reduction factor in the 20,000-hour test as our SAERTEX-LINER® MULTI, S+ product, which means a technical service life of 100 years.

Gliding and UV light protection foil

SAERTEX-LINER® INDUSTRY offers an integrated gliding and UV light protection foil as standard; there is no extra charge. This eliminates an additional gliding foil for liners up to DN 600 and a max. weight of 2.5 tons.

Extra time savings: option FastPlus

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

Chemical resistance tests

Once you provide information on the type of chemicals, their concentration, and the maximum temperatures of the flow media, our liners are then specifically tested to ensure their suitability for your application. Our product specialists will be glad to advise you.
