Maximum weight for blovk paving

[steps]

Hi

i am presently paving my front garden. Just wondering what is the maximum weight i can lay.

I have removed about 1/2 - 1 ton os top soil. Putting down 2 tons of hardcore, 1 ton of sand and approx 3 tons of paving. Is this too much weight. will it affect any walls nearby. I live in a terraced house sloping downwards so my neighbour to the left, has his garden slightly lower than mine and there is a wall seperating us. will it also affect the walls of my house. no cars are going to be parked on it, just walking.


thanks
