help remove standing water by making large rock (not limestone) filters toward the bottom of the sinkhole to divert water away from sitting on top of calcium carbonate rock (limestone).

help remove standing water by using pipes/drains to divert water from sitting on top of calcium carbonate rock (limestone).

all of these would help to mitigate issues like sinkholes.

Detailed explanation-1: -Sinkhole mitigation is mostly undertaken by regional and local governments. This can include continuous ground surveying using a range of techniques such as ground penetrating radar (GPR). More recently scientists have utilised space based radar information from satellites to indentify sinkholes.
Detailed explanation-2: -Three main types of grouting are commonly applied for sinkhole prevention and remediation: (1) slurry grouting; (2) compaction grouting; and (3) cap grouting. Slurry grouting is the injection of high-mobility grout with the main aim of filling voids.
Detailed explanation-3: -According to the U.S. Geological Survey, there are three common types of sinkholes: 1) dissolution, 2) cover-collapse, and 3) cover-subsidence.
