We have a very large grass area in the garden which has clay soil which has always has a wet boggy patch in the middle. However last year some new houses popped up at the end of our garden which are slightly higher than us and since then the grass has never dried out at all. The kids just can't play out on it.
Is there anything I can do to claim the area back and make it usable again?
For info, next door had a builder come and dig a soak away for him which has made no difference.
