Once all the steel work is done (ferro), the vault is ready to be cemented. Very much like slab day, the whole vault had to be smeared in its entirety in one day. That meant the crew had to get to the site around 6:30 am. We started by dry mixing sand and cement at a 2:1 ratio. That meant 6 wheelbarrows of sand and 3 bags of cement. Wet mixing is done in small batches in wheelbarrows with sisal fibers and immediately smeared onto the steel mesh. Since this was a huge task we hired two additional local workers who have experience working with ferro-cement on the island.

last little bit
At last, the first hull was complete. The crew was done by about 3:30 pm, totaling a little over 8 hours of work. In all, it took only 4-1/2 bags of cement, 9 wheelbarrows of sand, and 14 kg of waterproof admixture.
