Environmental clean-up

Securing and remediating contaminated sites form significant priorities in PORR Umwelttechnik’s activities. Complex contamination at old sites require intense preparation regarding the assessment of risks, variant studies, rehabilitation planning or the planning of an economically and ecologically feasible measure to treat the contaminated protective goods or, often, a combination of various securing and rehabilitation methods. In this context, we not only offer pre-treatment, removal and disposal but also encapsulation using cut-off walls, immobilisation, waste treatment, ground water treatment, soil vapour extraction as well as in-situ and ex-situ micro-biological treatment.

Before demolition work, hazardous materials, plastic mineral fibres and asbestos must be removed from buildings. Specific loosely bonded asbestos products, such as sprayed asbestos, mean that there are high protection requirements for both personnel and the environment when removing these materials from the properties. Our specialists, who have been trained in accordance with TRGS 519 and TRGS 521, possess many years of experience with complex projects in this regard.
