Sampling / Measurements

High quality and reliability are essential for sampling and measurements.
Especially within the scope of ongoing construction measures a fast and flexible project handling is also required. In order to avoid unnecessary costs, samples must always be taken and examined to a necessary and reasonable extend.
This requires experienced and qualified staff at sampling and at laboratory analytics.

Building fabric, waste, soils, soil gas, water or dust samples must be collected:

  • from the correct material
  • representative
  • from the correct zone / horizon
  • in sufficient quantities
  • with approved tools and methods
  • by qualified, independent staff.
Generally we examine the sampled material chemically and assess it subsequently.
if required (e. g. in order to test if asbestos is present) we also examine the material under the scanning electron microscope (SEM).
In many cases the results have enormous economic consequences

The LGA-IUA team consists of samplers and technicians with many years of experience. In addition to expertise for work according to TRGS 519 and TRGS 521 and technical qualification in accordance with DGUV Regulation 101-004 (formerly BGR 128), all our experts have completed the "Sampling in accordance with LAGA PN98" expertise training course.

We collect and analyze samples of the following materials independently and neutrally:

  • soil
  • soil gas
  • groundwater
  • surface water
  • wastewater
  • building materials
  • mineral waste
  • road superstructure and roadbed
  • roadside soil material
  • asbestos
  • artificial mineral fibers /AMF
  • dust
  • landfill gas
  • sludge
