Yesterday I had artificial grass installed in my back garden and it all looked perfect (apart from the grass being flattened due to it being rolled for a number of weeks prior to delivery).

Over night it rained quite a bit and was windy and today I have noticed a few patches of sand in lumps that makes the grass look like there are certain areas that grass is missing….

How I can solve this problem?
Also what is recommended to get the grass up right again?

Thanks

use a wet and dry vacumm cleaner on it or soft broom, an ordinary one will suck up water and eletrocute you probably
