I want to raise a corner of my garden because it slopes dramatically. I need to raise it about 40cm this will then make it just below the level of next doors garden . I was wondering what sort of materials i would use to raise it, should i be using grit, topsoil etc. I really have no idea. I will eventually lay a patio on top if that makes any difference.
mot=ministry of transport stone
basically its crushed limestone
very good for filling voids where you do not want it to subside
most builders merchants sell it
