I have looked at projects but no joy on info I require.
My garden slopes away from house in two directions so to lay patio I need to raise level. I have stepped foundations.
At the lowest point I would need 5 blocks (layed flat) at a length of around 4m to bring side up to level I require then step them accordingly across the front of patio then fill with hardcore.
I have 300mm width foundations and was going to peg at 150mm ready for concrete.
Is the 150mm concrete too much for the 5 high flat block or should I stick with that? I have read I could get away with 100mm ...would this be ok?
As I say, could not find any info in projects, If I have missed something please advise and I will look again.
