My view is that the ground cover sucked up all the available water and

That is but one problem. There isn't enough soil for a plant that size. And the plant
would not have appreciated fresh concrete near it, few plants do. And the heat would have
really done some damage. What area are you in?

BTW, test the soil for alkalinity, you might have to replace it before you replant.
