.the soil is not wet despite it being
raining heavy here the last few days.

if it is raining that heavily and the soil is dry then I'd try to cut down
on the drainage a bit - how about trying to work out where it is draining
from and putting a plastic covered plank with holes in across or something?
Alternatively most large garden centres now sell various Astroturf things.
