About inuma
inuma is an expert and consultancy office for building diagnostics and environmental measurement technology founded in 1999 in Dorstadt. Its range of services includes the investigation and assessment of building contaminants such as asbestos, KMF (old mineral wool), PCB, PCP and PAH, including contaminant registers and remediation concepts, mould diagnostics with remediation support and clearance measurement, indoor air measurements (VOC, SVOC, formaldehyde, CO2, dusts), thermal comfort measurements according to DIN EN ISO 7730, and workplace measurements according to TRGS 402. Material analyses for asbestos and KMF are performed using a scanning electron microscope according to VDI 3866. Clients include authorities and municipalities, companies with production and manufacturing halls, courts, construction companies, property management firms and private individuals. Remediation services are deliberately not carried out in-house in order to maintain independence. The focus of its area of activity is Lower Saxony, and for larger projects also other federal states.
