Pressure / Volume Controllers: Geodomiki

Geodomiki was founded in 1998 in Athens. Their facility is equipped to carry out all associated testing methods and standards for Soils, Rocks and Aggregates, within the Civil Engineering industry. Through a combination of high quality testing equipment and methodical testing practices, has enabled Geodomiki to work on a number of unique civil engineering projects, including road construction, deep foundations and earth dams. Geodomiki has been the laboratory of choice for many well known geotechnical companies, such as GAZETAS & Associates, GEOMELETI Ltd, LAMARIS & Associates and Developers like TEMES SA, for all their soil testing requirements. Founded in 1969, Neotek is one of the oldest and most specilased companies in Greece, for equipment and systems in the testing and measurement market. Neotek’s wealth of experience coupled with the high quality equipment they supply, puts them in the ideal position to advise and create solutions for your measuring and testing needs.

Geodomiki are a commercial testing laboratory for soil and rock mechanics. They were looking to expand their existing customer base and increase the number of tests they were able to perform. After consultation with Neotek(GDS Instruments agent in Greece) it was decided that if they could automate the testing procedures, they would free up time and resources to carry out additional and new tests, as well as improving the testing accuracy.


The product chosen to automate Geodomiki existing Triaxial systems, was GDS Instruments Standard Pressure / Volume Controller.  “We purchased GDS equipment to reliably respond to the challenge of our customers“, says Thomas Tassios, Geotechnical Engineer at Geodomiki.

The STDDPC, typically operating at 3MPa/200cc, provides a cost-effective direct replacement for conventional soil mechanics laboratory pressure sources and volume change gauges. The device has its own computer interface and can be controlled directly from a computer. It is ideal as a back pressure source where it can also measure the change in volume of the test specimen. In stand-alone mode, the device can replace traditional laboratory pressure sources such as mercury column, compressed air, pumped oil and dead weight devices. It is also a volume change gauge resolving to 1 cu mm. 


…“We are very happy with the GDS Controllers. We would definitely re-invest in GDS equipment and depending on current market are looking to invest in at least 2 to 6 additional controllers, says Thomas Tassios Geotechnical Engineer at GEODOMIKI”.
