Our services: Testing for sewer renovation projects

Standard material testing about the technical characteristic values are set in CIPP and other sewer renovation techniques. As an independent, accredited testing laboratory we document your remediation project success and certify if the construction site samples comply the requirements regarding to the mechanical characteristic values. Next to the bending strength it affects the determination of the wall thickness und the modulus of elasticity (E-Modul).

You create values for generations. We deliver the proof.

All testings are according to the procurement and comply with the requirements to the current sets of rules (DWA-A 143-3, DIBt-admission).

All testings are used for controlling so that the delivered quality is equal to the ordered quality. Any questions to the requirements, provisions or sampling? We are happy to answer you.
