Summary:Knowledge of the leaching behaviour of construction materials is necessary for the assessment of mobilized environmentally hazardous substances. The influence of construction materials on soils in the surrounding of a building is being increasingly discussed. For this reason leaching tests are intended. For the assessment of the release behaviour of grout injection eluates obtained by the inverse column test. The investigations concerning the assessment of impacts of grout injection materials, particular polyacrylate, on soils and groundwater resulted to a closely limited release. After less than 24 hours, the level of the initial value has been reached. Ecotoxicological tests partial showed high adverse effects. Because the substances are easy degradable, a long term impact on soil and groundwater is not expected.
