Is there a chance the concrete will crack?
Yes, there is always a chance that concrete will crack. If it was to crack it would be very subtle and appear as a hairline through the concrete. With outdoor pieces such as fire pits, the edges near the burner get hot and the outside edge can be very cold, causing expansion and shrinkage and potentially, a hairline crack. These are not structural and will not affect the performance of your fire pit.
On kitchen counters you may get a hairline crack near the edge of the sink or the tap. For more details please read our warranty tab. (Above)
