Substrate testing in accordance with all relevant regulations

We conduct comprehensive suitability and quality control tests on substrates for sports field construction, landscaping, and horticulture. In our in-house, ISO 17025-accredited testing laboratory, we independently test substrates and mineral mixtures in accordance with applicable DIN standards, RAL quality and testing specifications, FLL guidelines, as well as relevant ZTV, TL, and other technical regulations.

Among other things, we test:

  • Tree substrates
  • Turf base layers and tennis court surface layers
  • Gravel turf
  • Drainage layers and dynamic layers
  • Base layers without binders / unbound base layers
  • Water-bound path surfaces
  • Roof garden substrates and planting substrates
  • Materials for riding arenas
  • Golf course construction materials

The tests are conducted in accordance with, among other things:

  • DIN 18035 (Sports Field Construction)
  • RAL Quality and Testing Specifications (e.g., RAL Quality Mark for Substrates)
  • FLL Guidelines (including for tree planting, green roofs, sports surfaces, and golf course construction)
  • ZTV and TL (e.g., ZTV Landscaping, ZTV SoB-StB, TL Substrates)
  • USGA (Golf Course Construction)

Our independent testing provides building owners, planners, and municipalities with planning, execution, and legal certainty. We support projects from suitability testing through on-site monitoring during construction to final acceptance - with clear documentation and expert advice.
