I have started to change the shape off my drveway to fit two cars on it. I have removed a flower bed and grass area est 12 msq. I plan to fit 50mm 600mm x 600mm flags so i have dug down just over 300mm. But the ground is firm but can drive 3x2 wood stake over 150mm. If i dig 1ft to 2ft further i get to sand.
could anyone give me some advice if this is ok??
or anyway to get round it
