Hi,

My back garden is approximately 60' x 25' and slopes from front to
back and slighly from left to right. The house is in North London and
as is typical for the area the soil has a clay consistency resulting
in drainage problems.

Someone has advised me that I should dig a hole about 2mx1m by 1m deep
in the lowest point of the garden (which is the bottom right) and fill
it with bricks stones etc. Is this actualy a good option?

I've looked in Google and I have seen references to this being done so
I suppose it is not a bad idea. Where the hole will be dug is an
unused part of the garden so it will not be a big problem.

One reference I saw on Google seemed to indicate that the rubble
should be clean which I took to mean it should not have loads of
cement. Last years project was to tear down our old patio and build a
new one so I have a lot of rubble left over from the old demolished
patio can I use this?

Thanks
Andy
