Road Laboratory Szczecin provides comprehensive laboratory services for construction investments ensuring the highest quality of even the most complex construction investments. We carry out tests of the load capacity and compaction of the existing subsoil, collection of excavations by authorized geologists, compaction of backfill of installation excavations, compaction and load capacity of the improved subsoil as well as embankment and structural layers, testing of fresh concrete mix and hardened concrete, as well as mineral asphalt mixtures and prefabricated elements.
Our greatest asset is widely understood consultancy at every stage of a construction investment.
All laboratory tests are carried out at the premises of Road Laboratory in Szczecin at 92 Goleniowska Street. We do not send samples to other laboratories in the country, which allows us to maximally shorten the completion date of orders.
