TamSoil 700CP is a unique liquid polymer especially designed for the use on EPB tunnel boring machines tunnelling below groundwater level. This polymer is used in ground conditions where foam alone is not enough to handle an increased amount of water. TamSoil 700CP is especially efficient in soils with low fine particle content. TamSoil 700CP also lubricates moving parts, lowers friction and wear, which extends the tool life and decreases energy requirements.
