Geology

We can build on the tradition of being initially a geological laboratory and can follow up on historical surveys, analyses and results.

We know that for our clients, it is essential to assess the effectiveness of the intended steps and procedures or the effect of the quality of raw materials on subsequent production.

Who are our clients?

• Lime works, cement plants, glass works, quarries, manufacturers of building materials and products
• Smelters, foundries, mining companies
• Brick industry

What do we offer?

• Tests of raw materials and division into types (types of clays, loess, soils...)
• Technological tests of raw materials and mixtures for bricks
• Granulometric analyses
• Chemical analyses
• Section and map construction (in cooperation with a partner company)
• Estimation of raw material reserves (in cooperation with a partner company)
• Drilling work (in cooperation with a partner company)
• Resolution of conflicts of interests, changes to POPD (plan of opening, preparation and extraction) and DP (extraction area) (in cooperation with a partner company)

Granulometric analyses:

• sieve analysis
• Andreasen sedimentation analysis with determination of particles below 2, 2-20 and above 20 m

Technological tests:

• determination of formation water
