Injection mortar has a soft to runny consistency. It is used when repairing lateral connections by robot, for later sealing of leaking sections, especially in water conservancy areas, injecting cracks, and stabilising the soil in new-build situations. Even quite large leaks can be sealed off with injection mortar, even in the presence of flowing groundwater. Thanks to cement injection technology, large quantities of mortar can be handled in a very short time. In this way large cavities can be filled so as to take a static load. Grain-size (always < 0.5mm) can be determined according to the individual situation.
