For treating contaminated soil we have the biggest integrated network of self-owned stationary and mobile soil-purification plant in Germany. This plant employs chemical and manual treatment processes developed by us. In this context we move more than two million tons of contaminated and treated soil and soil-related materials from - and later back to - its natural and economic environment every year.

Contaminated soils usually also tend to contaminate the groundwater. One of our central tasks is to reduce this source of danger. In this context we effectively combine the widest variety of approaches, even if, for example, oil or fuel is involved. To this end our engineers are continuously developing new engineering processes, to the benefit of mankind and the environment.

Wherever industry releases emissions, whether in commercial works or in purification or composting plants, we free the air of its odorous substances and impurities - reliably and economically. Air contamination can also have its origins in the soil. In such cases we extract the pollutants from the soil or groundwater in a current of air, and then convert these biologically.

With the help of our materials-flow management we are able to protect resources, reduce CO2 emissions and save on costs. Employing our know-how we can create lasting cycles that can, for example, convert oil-contaminated, perishable packaging materials to chemically uniform secondary plastics using a self-developed process. This makes it possible to produce a high-quality, reusable grist for recycling derived from essentially unused waste material.

With a combination of competence and experience gathered over decades, we are able to free our land from all sorts and quantities of residual pollution and contaminants. Whether industrial or trade areas, military matters or fallow transport areas, our specialists can develop a clean-up concept for in every case - and all from a single source. This enables us, taking a case in point, to revitalize developed real estate in the best locations, instead of always seeking new areas for further urbanization.

Our specialists for fireproof construction plan, produce and mount fireproof materials throughout Europe, in distant ports and even on the high seas. The materials employed include concrete, stone and ceramic fibres, which can withstand temperatures of up to 1200 degrees Celsius at the widest variety of fire-points. Where necessary, we can also prepare any special moulded parts required in our own works.

Our chimney-construction teams achieve high-performance at great heights. We undertake the construction, the sanitation and the servicing of chimneys made of steel, brickwork and reinforced concrete. For our customers we also undertake requested demolition, including subsequent disposal.

Optimal insulation measures serve to save energy and improve efficiency. For this reason insulation systems make an important contribution towards protection of the climate and the environment. Our companies provide the knowledge and the appropriate insulating materials for industrial and technical building installations. Remedies for pollution in offices, industrial plant and public buildings round off our performance portfolio.
