One may begin from a corner and proceed along both sides paying attention to maintain perpendicularity. If this method is adopted, one has to proceed by completing single rooms.
In case of long walls, another procedure to be used is the following: Begin from a wall and continue by placing perpendicular walls on a frontal advancement.
Before the Shotcrete Application
By placing the scaffolds on the internal side, it is possible to rapidly apply the shotcrete on the external side.
Place reinforcement meshes before applying shotcrete.
Remember that the plumbing of walls is absolutely necessary.
The shotcrete to be applied may be a premixed type or prepared on site. In any case it must have the following characteristics:
- Ordinary Portland Cement (OPC)
- Sand of a diameter 0-6 mm (0-1/4 in)
- Cement/Sand (in volume) = 1/4
- Water/Cement (in weight) < 0,52
- Hydro repellers
- Polypropylene fibers
- Cement based
- Not less than Grade 25MPa (3556 psi)
The shotcrete should be applied on the walls in two consecutive layers, the first of which, will be sufficient to cover the steel mesh.
