Our garden is completely waterlogged. Since moving here 5 years ago, we have put in a French draining system ourselves, but it has made very little difference. Even now after little rain and lots of sun, our grass is sodden and we have 3 young children, we can't let the children on it very often as they just get so wet and muddy. We have a trampoline and a TP climbing frame thing but we are just gutted as we want the children to be outside as much as possible and we just can't let them. Any ideas what we can do to help improve drainage? I really don't want to gravel it all- my little boy loves football
