Krejci Engineering was founded in 1989 and produces vibration machines for concrete compaction on the basis of Ing. Ilja KREJCI's academic and research experiences. Until 2000 the vibration tubes were produced in parallel by GEOtest. Since 2000 the production of vibrating machines using vibrating tubes in the VS 560 VIBRATION TABLECzech Republic has been solely by Krejci Engineering.

Further development of compacting technology products is now made by Krejci Engineering. This development includes the compaction of concrete mixtures, ceramic materials and the construction of vibrating devices.

The most popular devices are vibration tables and the main feature is their very robust design, which ensures a service life generally in excess of 10 years. Robust construction also prevents higher harmonic vibrations that cause the noise emission. This means that the company has contributed towards solving the main negative features of concrete compaction technology - vibration and noise reduction, which significantly decreased threats to the health and safety of workers. It should be noted however that noise can never be completely eliminated.

Currently Krejci Engineering has 8 employees and their main programme is the production of vibration tables for use in the compaction of concrete, fire-resistant concrete and ceramic mixtures. The company also participates in development R&D projects, such as steel compaction using vibration technology, and produces large machines frames from high quality concrete.
