Not sure if this is in the right place, but here goes, I'll start a new thread. I was on the Beach in Dgte once and just taking in the views etc walking along the beach, i walked past 2 Pinoys with a sack and they were filling the sack up with sand from the beach. i wondered what they were doing, I walked on a bit and turned back to see the 2 guys take it up to the Beach front house, a very nice house, and i stoped and watched as they went up the steps and went into the house and they emptied the sack of sand on the floor. (it was like a covered patio area ) they then proceeded to mix up cement!! obviously to use it there and then. I was horrified!! I am no master builder, but I know that you never use beach sand to build with, as it has not been washed and processed for building. even if Bricks or blocks are soaked in seawater, they are rendered useless for building, you can never wash the salt out of them. So then I got to thinking....what if the whole house was built with beach sand!! and whats more did the owners of the house know of what was going on? I suppose only time will tell.
