How to pour a concrete slab on an already existing concrete slab having a false-level towards the house? It should be noted that at the lowest can not exceed 4 cm is at the highest 6 cm. Can we make fiber concrete? Is it going to last in time knowing that we expect to tile it directly within a year?
It is not necessary to pour fiber concrete on an existing slab to make up a difference in level of a few centimeters. You can settle for make a mortar screed, whose purpose is both to planify an existing soil and to correct any differences in level. If you need to, you can even make a patch (fiberglass), designed for a maximum thickness of 5 cm.
