We have a lovely lawn if we stay off it !,but the temptation to walk
bare foot is too great, and as we have have far to much rain of late,
and the fact that now the kids are off school the lawn is going to
suffer.
The problem is that the soil is far to clay in its make up and so even
airiation with a fork soon gets compressed into a water proof surface,
i have contemplated spreading sharp sand but at what volume eludes me,
i am told Limeing but only as a last resort, the grass is perfectly
happy but i am not, so with that in mind any suggestions as to how to
cure this and add good grainage before i rip the whole lot up and start
again would be much apprieciated.

Gypsum is sometimes called the "hoe for clay" or something to that effect.
I bought a skip full of broken bags at the end of the year a few years ago -
with some success.
