How in the world could this happen?
A slab on the walkway to my front door is cracked and sinking in. They are only about 5 years old and I'm sad that one is already looking this bad. It's about 3 feet wide and 4 feet long. How much would just one of these slabs cost to replace? I'm trying to figure out if it's even worth it because I'm not sure it would be possible to match the same color as the others. I want to know how this happens so I can prevent it from happening again and wasting money.
