To make the tank, you will have to pour your water-repellent mortar back into the container and then pass it on the walls. The most recommended is to apply it on a thickness of 12 to 18cm. It will then be necessary to fix the flashings in order to obtain a gap between the wall of the tank and the floor and then spread the mortar on the floor if necessary. Let everything dry for a while.
