The company Heinrich Wassermann has contacted us, to find a common solution
for the following building place.
For the construction of the branching building with connection to the relief
collector Wupper was requiredly an approx. 11 m deep excavation.
By the surface near groundwater level you sealed up first of all with HDI
(jet grouting) The following digging of the excavation, the reduction of
surplus HDI (jet grouting) and rock was supported, by an Erkat-rotary drum cutter type ER 250, which
was hired by Klaus Melchior Industrievertretung GmbH from Duisburg.
The building place was carried out at short notice and fast.
