A couple of weeks ago we had some brick-pavings re-cemented around our driveway. Now all of the grass on the lawn that runs alongside the bricks has gone very orange. I assume it was where the cement/sand mix was brushed onto the grass to clear up after the work.
I read that cement is high in alkaline. Would that have been the cause, and can grass recover naturally or should I purchase some kind of treatment, as opposed to scarifying it out and re-seeding?
