About us
Geotechnisches Büro Dr. Leischner GmbH is an engineering office in Bonn that has specialised since 1963 in the investigation and assessment of soil, groundwater and contaminated sites. Its services include geotechnical investigations and assessments of subsoil load-bearing capacity as well as economical foundation proposals, the recording and evaluation of legacy landfills and contaminated sites, concepts for building deconstruction and disposal of industrial and commercial buildings, and the planning of safeguarding and remediation concepts for contaminated sites. Further focal points are the assessment of the stability of slopes and embankments, hydrogeological investigations for infiltration systems, suitability tests and compaction controls in road and dyke construction, deposit exploration, expert witness services, the preparation of water rights applications and the planning of groundwater development measures. Since 2000 the office has been operated as a GmbH; the managing directors are Edgar Mohr and Anke Leischner-Fischer-Appelt.
