About us
Dr. Pelzer & Partner is an independent engineering consultancy based in Hildesheim that has been offering services in the fields of geology, hydrogeology and engineering geology, soil and environmental protection, subsoil, water and waste management, and building contaminants since 1996. The company, with around 20 employees, is organized as a Partnerschaft mbB to underscore its status as an independent and self-responsible expert organization. Its services include subsoil and groundwater investigations, soil-mechanical laboratory testing, geotechnical reports and proofs, site investigations, contaminated site investigation and remediation including innovative in-situ methods, building contaminant surveys, groundwater monitoring and landfill surveillance, stormwater infiltration, geoinformation (GIS) as well as initial status reports (AZB) under the IE-RL/BImSchG. For fieldwork and sampling, four sampling vehicles, small percussion drilling rigs, probing devices, concrete core drills, dynamic probing devices, plate load test equipment, and on-site measuring instruments for water, soil and air are available; chemical analyses are performed on a project basis with accredited laboratories. The focus is on the Hanover-Braunschweig-Göttingen-Wolfsburg metropolitan region, with additional projects in the wider domestic and international market.

Investigation methods and laboratory
Historical research
Evaluation of files, maps and aerial photographs to derive a contamination hypothesis and an investigation concept.
MIP probing (Direct Push technology)
Direct measurement of substance concentrations in the subsurface to detect contamination plumes, especially in chlorinated hydrocarbon (CHC) contamination.
Small percussion drilling and dynamic probing
Direct and indirect exploration methods for subsoil investigation with levelling of the drilling starting points.
Core drilling using the rotary flush method
Sampling in paved surfaces from soil, rock, asphalt and concrete with 40 to 152 mm diameter.
Plate load test (static/dynamic)
Verification testing of compaction quality for earthworks, sewer construction and road construction projects.
Soil-mechanical laboratory
In-house testing of water content, grain size distribution, loss on ignition, density, consistency limits and shear strengths.
Geoinformation (GIS)
Consolidation, evaluation and visualization of spatial data, among other things for contamination anatomy and for area and volume determination.
Groundwater modeling
Computer-aided modeling of groundwater flow and substance transport for remediation, construction dewatering and seepage water forecasts.
