Hi! Could you give me some advice?
Got a porch built, but for some reason the builder didn't include the porch floor. I think I can raise it to the level of the rest of the house with the help of a friend. Internal dimensions are 1700x1100 mm and I have to raise it by 300 mm.
This new porch was built partially on top of the old porch, so the floor is concrete but there is a 20 cm strip where is just soil.
What do you think about a new hardcore base, sand, 300 mu dpm, 150 mm concrete and 100 pir board? Can you suggest a better way to do it?
Thanks
