Can Sinkholes Be Fixed

If the sinkhole is not affecting a house or other structure, and has a reasonable size — 2 to 5 feet in both diameter and depth — then you can repair it yourself. A large sinkhole will most likely require excavation and a more complex filling operation.

How do we repair sinkholes?

1. Step 1: Excavate the sinkhole down to rock if possible.
2. Step 2: Put a layer of large stones in the hole (cabbage size).
3. Step 3: Put a layer of smaller stones on top (fist size).

How much does it cost to fill a sinkhole?

Moreover, not all foundation repair companies are created equal. For example, a small sinkhole which minimal damage to any surrounding structure can come to a sinkhole repair cost of $10,000 to $15,000; a larger sinkhole can reach the $100,000 mark or more, depending on the sinkhole and the damage it causes.
