Removing artificial grass
« on: May 11, 2022, 11:25 »
Hi all,

I moved house last year and am going to remove some artificial grass to replace with raised beds and turf. Underneath the astroturf is quite a deep layer of granite dust that prevented weeds from growing through it.

Just digging out a 4ft x 4ft square I managed to 1/3 fill a 1 tonne bag with the stuff so completely removing it is going to be a nightmare. Is there anything wrong with just digging deeper and mixing it into the soil?

Thanks in advance for your replies

Are you sure it is granite dust, or could it be something else e.g. limestone?
I try to take one day at a time, but sometimes several days all attack me at once...

If it was laid properly it will be granite dust. I canít see why you canít incorporate this with the soil. It will give you a gritty texture. Not at all bad.

Thanks for the replies. I think it's granite dust, as it seems to have been laid very well. Is there any way of telling?

Carefully drop a smidge of battery acid (or it may work with strong vinegar) and if it fizzes it's limestone.  If not it's granite.  Cheers,  Tony.
I may be growing OLD, but I refuse to grow UP !

I'd avoid trying battery acid (concentrated sulfuric acid contaminated with lead and antimony).

Drop a bit of the suspected granite dust into a clear glass with vinegar. It will react more slowly, but will produce a slow fizz.

A geologists field kit for this test is a dropper bottle with 10% hydrochloric acid (=muriatic acid).

Limestone is usually softer than granite (except where it contains incorporated sand or silicified  fossils).
Please stay safe!  Wear a mask, and observe social distancing!
