I.S.T. GmbH, based at the heart of the Ruhr River Valley in Bochum, Germany is one of the most successful and innovative comprehensive suppliers for pipe and sewer rehabilitation in the world.

For some time now, our internationally-recognized Strobel System for the rehabilitation of damaged side connections via the grouting of a special mineral-based mortar, has been manufactured at our headquarters.

Similarly, we produce various consumables such as Felt Top Heads for "Joint Rehabilitation" in quantity at our works in Bochum. Several Felt Liners are mass produced here as well. Numerous service and repair functions are likewise carried out at our service centre adjacent to the I.S.T. GmbH headquarters. Nowadays, we even have the capacity to bring products originating from other manufacturers back into working condition.

The Service centre guarantees our customers reduced downtime and, thereby, utmost efficiency when working with our equipment. Should a longer time be required for a repair nonetheless, we set aside equipment for a great many of our products to loan out for the duration of the repair. Extra units are made available to provide our customers coverage during peak periods of rehabilitation work as well.

Our Spot Repair System is among the most successful products in Europe and has recently been certified by the German Institute of Construction Technology (DIBt). This system, the most popular of the past few years, has garnered outstanding results from numerous test reports. By obtaining exclusive rights worldwide to sell the excellent products of the company seal-tec®GmbH worldwide, I.S.T. has taken another great step forward in 2005 towards becoming a fully "complete provider" of products in the sewer rehabilitation industry.

In addition, many custom requests (for special sizes of liners and felt Top Hats in particular) can be fulfilled "just in time" for our customers.A warehouse capacity of roughly 2000 m2 allows us to permanently stockpile the most important consumable materials so as to ensure immediate delivery to our customers.

Comprehensive training in our products and technology as well as support on customer on site is, as a matter of course, of great importance to us.
