Check a building plot in Czechia before you buy or build
GroundSurf combines Czech cadastral evidence with national geological, borehole, hydrogeological, radon and mining context while keeping map evidence separate from site-specific engineering conclusions.

RÚIAN/ČÚZK evidence can support parcel and building-registry context. Registry buildings are evidence only and are excluded from any land-value scope.
Czech Geological Survey evidence provides mapped geology and nearby subsurface observations. Nearby records do not establish the parcel's full stratigraphy.
National hydrogeological evidence is used as screening context without inventing a parcel groundwater level or foundation design parameter.
Where national evidence is available, GroundSurf surfaces radon and mining-related screening records together with their source and limitations.
What still needs verification
Local planning, legal boundary questions and geotechnical design must be confirmed from the responsible authority or by the appropriate professional. Automatic Czech land valuation remains off rather than using a generic fallback.
