The securing and remediation of contaminated sites is a key focus of PORR Umwelttechnik's work. Complex contamination at contaminated sites requires intensive preparation in terms of hazard assessments, variant studies, remediation planning or the development of economic and ecological measures to treat the contaminated protected assets. Often, a combination of several safeguarding and remediation procedures is necessary.
In addition to pre-treatment, clearance and disposal, our services also include enclosure with sealing walls, immobilisation, waste treatment, groundwater purification, soil vapour extraction and in-situ and ex-situ microbiological treatment.
In many cases, pollutants, artificial mineral fibres and asbestos have to be removed from buildings before demolition work. Low-bound asbestos products in particular, such as spray asbestos, place high demands on the protection of personnel and the environment during removal from the objects. Our specialists, trained in accordance with TRGS 519 and TRGS 521, have many years of experience in this field.
