Test & Inspections

EXPERTISE

We conduct tests and inspections focused on the critical parts of road and railway tunnel infrastructure in order to assure the highest safety level. Key partners of our company are reputable professionals and accredited laboratories in order to achieve the highest reliability and scientific justification of the results and services that we provide to our customers. Our company owns high tech equipment capable of meeting the demanding conditions imposed by road and railway tunnels environment, contributing to the reliable conduction of tests and inspections. The methodology our staff uses to successfully carry out tests and inspections is based on international standards, guidelines and good practices applied globally for similar activities. 

We conduct tests for measuring:

  • ventilation performance
  • fire resistance
  • thermal & mechanical properties

Fire resistance tests

Our personnel include Engineers with a great experience in fire testing and the behavior of construction materials under high temperatures and fires. Apart from that our company is equipped with a customized mobile furnace for testing the fire resistance and fire protection of building and passive fire protection materials. The furnace can conduct tests on specimens from 10cm x 10cm till 120cm x 120cm either in the laboratory facilities of the company or in situ on the structure. The furnace is accompanied by the appropriate declaration of conformity issued by the manufacturer, while the entire procedure for testing the materials has been validated by an accredited body through Third Party inspection. The temperature in the furnace is controlled with 5 thermocouples. Apart from the thermocouples, a fire-resistant camera is installed (built in the furnace) in order to have a visual inspection of the fire protection system testing or the concrete during the test. By this way the spalling or damage of the material can be observed during the test.  The burner has a capacity of 355.000 kcal and functions with LPG (liquefied petroleum gas), using 18 gas cylinders and has the ability to simulate all standard fire scenarios, ISO834, RABT, RWS, Hydrocarbon (HC, HCM).

Thermal and Mechanical properties

Our company focus its research on the thermal and fire resistance as well as the behaviour of the construction materials and protection materials. On this purpose we have gained great experience on the assessment and investigation of the thermal and mechanical properties of several materials. By investigating the results of several measurements, it is easy to understand the condition of a material or a structure after a fire, declaring whether the whole structure should be remanufactured or make minor changes and improvements. These properties include thermal conductivity, thermal expansion through dilatometry, porosity, specific heat, mechanical properties before and after the fire, as well the investigation of the effect on the mechanical properties of the material by measuring the compressive strength under thermal loading (e. RILEM 129 ,200), thermal shock, etc. We are involved in the core drilling for the specimens and in collaboration with high level research institutes, we examine and investigate each material according to the project requirements.
