The investigation of mineral building materials requires a very careful approach because sampling will affect the test results considerably.

Independent sampling in accordance with relevant standards by an accredited test laboratory will guarantee representative results.

Testing aggregates for further processing in concrete, tarmac, bound or unbound mixtures, or railway track ballasts is an essential component of production control.



We are looking forward to supporting you.
