OL‑TRANS Laboratory

At OL‑TRANS, we place great emphasis on the quality and stability of the parameters of our concrete products and precast elements. Thanks to an implemented and continuously improved Factory Production Control System, we create optimal production conditions and guarantee products with consistent and predictable properties. Every stage – from raw material selection, through mix design, to production on modern equipment – is meticulously monitored.

We operate our own laboratory, where we conduct detailed testing on both fresh concrete mixes and finished products. This ensures that our clients can trust every product meets European and national standards, with production processes carried out according to the highest quality criteria.
