Pressing groundwater or layering water is particularly dangerous for manholes and other shaft facilities. Masses of water can build a huge pressure on the foundation and walls. The water must be constantly sucked off and disposed of via separators. This damages unprotected metal pipes, because the permanent water level accelerates corrosion.
We won't let the water get that far. And keep it far away from the Shaft: We seal mineral substrates with ISO fluid in such a way that they withstand a pressure of 15 mWS. ISO fluid is a special 2K product that sits down wedge-like between the media (metal/mineral), swells and connects to the mineral substrate in no time.
