Lučební závody Draslovka Kolín Co. – cut-off wall designed to prevent contamination spreading from chemical operations

This contract consisted in carrying out a cut-off diaphragm wall from the SEKOFIX mixture that would prevent free circulation of contaminated ground water from the chemical operations of Draslovka Kolín Co. to its surroundings. These are remnants of past environmental burdens originating from the 1st part of the last century. During the bombings of the 2nd World War the chemical operations were destroyed and large amounts of chemicals leaked into soil. After the cut-off wall is carried out the captured contaminated water will be pumped through 16 boreholes and further filtered in a wastewater treatment plant. The technology of excavated diaphragm walls and jet grouting to bedrock level including fixing into bedrock to the level of approx. 1,0 m was used to carry out a part of the cut-off wall. High-pressure gr outing was used to inject the bedrock.
