4 Common Limestone Problems and How to Avoid Them

May 03, 2016  4 Limestone Problems that You Might Come Across and How to Avoid Them. Weathering: Limestone is a rock which is more prone to especially chemical weathering than other types of rocks such as granite. This is because calcium carbonate, which is one of the minerals found in limestone, readily reacts with rainwater.
