Top dressing lawn..

I have a large lawn, it is fairly flat with some slight hollows..it is on clay soil and tends to be moist most of the time...
Could I top dress with bulk bags of sharp sand to aid drainage and to fill slight hollows..
Cheers.

 

Thanks John, would the normal builders sharp sand be ok?

 

Aerating prior to top dressing would be essential and sharp sand is spot on. Just make sure it doesn't smother the grass. Though once aerated you'll be surprised how much of the sand the lawn will swallow when raking in.

How many hollows are we talking about? If it's only a few you can cut to peel back the turf, under fill with soil then fold the turf back over. If that's the case post back and we'll talk you through that. If not it would be easier to just fill the hollows with a good quality topsoil then overseed. If you have access to a trulute you could always shave the crests in the lawn but it really depends how big an area/how much time you have/which method would work best for you.

 

Thank you very much for the information...
The lawn is approx. 120ft x 50ft, there are quite a few hollows...you cant actually see them but you can feel them with the lawn mower(Qualcast Suffolk Punch)..
Im trying to sort out a couple of bulk bags of sand...is sharp sand the same as concreting sand?
Cheers..
