Vertical water cutoff wall technology preventing contaminants leaching into soil or groundwater
The Trinner method is a vertical water-cutoff wall technology that prevents contaminants from leaching into surrounding soil and groundwater by using blocking and seepage control work to enclose the contaminated soil.


The Trinner method combines two techniques that have been well used: the diaphragm wall water-cutoff method (soil cement wall) and the sheet-type water-cutoff method. Using the merits of each makes for a highly reliable water-cutoff wall method.
