Two loads of sand, one and a half loads of gravel and 100 bags of cement. Of all that we had about a half load of sand left, a quarter load of gravel and used exactly 100 bags of cement. There is also about 120 pieces of six meter rebar under the cement on a 120 square meter roof.
No cement pumpers used here - it was the bucket by bucket brigade up the street side of the house. Street was closed to all but bicycles for almost 4 hours. The roof foto only shows the beginning of the pour but it is all up there. My job now is to water the roof at sunrise and sunset so it dries slowly.
