Actually, this method still comes from Father Li's years of experience making cement pipes.
Spraying it with water helps enhance the flexibility of the wall.
Plus, with the scorching sun over these past few days, the freshly mixed mortar is prone to cracking under the heat.
The progress these days has been fast; seventy percent of the wall has already been built.
Over a hundred people have been constructing the wall for the sixty-acre Second Outer City, covering 40,000 square meters.
It means that the length and width are each 200 meters. Since the Inner City Wall is already in place, they only need to build walls on three sides.
That's a total of 600 meters of the wall.
600 meters, which equals to roughly half a meter per person over these five or six days on average.
The pace is gratifying.
It seems that in just another two days, the wall will be completed.
