How to fix sinkholes
Monitor the hole to see if it grows.
Sinkholes are often triggered by weather phenomena, such as a heavy rainstorm. Once a sinkhole has formed, though, it can continue to grow, as further portions of limestone or other carbonate rocks fall away.

Select from:
[1]. Check your nearby locality, if it continues to form sinkholes. Sinkholes can be potentially dangerous if you happen to happen upon them as part of a natural disaster.
[2]. Sinkholes are not necessary if you live in an area that has muddy roads. It's better if you check once a year to see if the sinkhole is larger than you expected, as sinkholes are sometimes tricky to remove and are faster to remove.
[3]. As long as a sinkhole continues to grow on a day-by-day basis, do not attempt to fill it in. Once the sinkhole has stopped growing and remained the same size for a few days, you can fill it in.
[4]. Sinkholes are also triggered by rainfall in urban areas. Test the sinkhole if it is big.
