First Tile Vault on Mfangano Island

We finally hit a point where we could have a training day and have The Guild learn the tile vaulting technique by building a scale prototype of the vault we are going to build for the radio station. It is a saddle vault with different end arches. The guys were absolute naturals and got a hold of the technique right away. It took demonstrating a few times and very quickly they were building on their own, getting a feel for the plaster mix and most importantly the sequence of laying out the tiles. 

Within one day we were able to build the biggest vault we have built to date: 5ft x 8ft foot print with end arches at 3.5 ft and 5 ft. The 1inch thick tiles were fabricated at our own brickworks using sub soil from the worksite, cement (about 12%), a little bit of sand and some fibers. The gypsum plaster was brought over with us from Kisumu.
