At the request of the roof contractor who was afraid that the posts, because round, could not take the 20 tons of tiles and 10?tons of woof under, I got from Chiang Dao these thicker cement blocks, all they had, and had these built
There is no doubt in my mind that this is overbuilt, I've built house in wood able to support one metre of ice...
But I'd rather pay 20 tbh per block and do it like that and have everybody happy!
