Product quality
Plastic products accompany us all day long and mostly for our entire live. Often the focus is on a safe operation, a high degree of practicality and a long service life. The competence of SKZ as a testing laboratory is required if geosynthetics are to be tested, which are expected to be designed for a long service life.

The SKZ testing laboratory is independent and neutral. It is accredited in accordance with ISO/IEC 17025, tests plastic products according to approx. 1 000 standards. The testing lab has a size of about 6 000 m². Usually, these testing activities go hand in hand with our quality assurance activities which are initiated by our inspection body accredited in accordance with ISO/IEC 17020.

We test the widest range of geosynthetics such as geotextiles, geogrids, geonets, geomats, geocells, geostrips, geospacer, polymeric geosynthetic barriers, clay geosynthetic barriers, bituminous geosynthetic barriers, drainage geocomposites, reinforcement geocomposites, geofoams and geosynthetic erosion control products.

The absolute neutrality and independence in combination with the expert knowledge accumulated for more than 50 years guarantees that we are an expert, competent and reliable partner for all questions on the subject of “plastics”. For this reason, we stand with our name “SKZ – Das Kunststoff-Zentrum”.
