What causes sinkholes in North Georgia?

Many are caused by water washing soil into a buried debris pit, old tree stump cavity, broken drainage pipe or natural void. On acreage, concentrated runoff from roofs, drives or gutters is usually the trigger. True karst limestone sinkholes are less common here than in Northwest Georgia, but any buried void can collapse if water keeps feeding it.

Can you just fill a sinkhole with dirt?

You can, but it will likely come back. The void formed because water carried soil away, so the fix has to include stopping that water and rebuilding with compacted structural fill rather than loose topsoil that washes out again.

Is a sinkhole near my foundation dangerous?

It can be. If water is eroding soil against or beneath a footing, slab or driveway, the problem can worsen quickly. We assess whether the sinkhole threatens a structure and prioritize stabilization before it affects the building.

How long does sinkhole remediation take?

A small yard sinkhole may be resolved in a day or two once the cause is clear. Larger voids, repairs near structures, or jobs requiring drainage redirection can take longer. We scope the work after investigation so you know what to expect.

Water first

Sinkhole Remediation & Sinkhole Repair in North Georgia

Sinkhole remediation, subsurface stabilization and collapsed ground repair for properties across North Georgia.

A sinkhole is rarely just a hole in the yard — it is a sign that water is finding a path underground and carrying soil with it. Filling it with gravel or topsoil without fixing the water source is a temporary patch at best. We investigate what caused the collapse, remove the unstable material, rebuild the subsurface with engineered fill, and route water so the void does not reopen.

Part of our Drainage & Erosion Control in North Georgia work across North Georgia.

What we see most often

A depression or sudden drop in the yard that keeps getting deeper
Soft, spongy ground that swallows water after every rain
Repeated sinkholes reopening in the same area after backfill
Erosion tunnels or voids forming near foundations, driveways or drainage outfalls

Scope of work

What this work includes

Cause investigation

We trace the water source — whether it is a broken drain, roof runoff concentration, natural limestone feature, or an old buried debris pit — so the repair targets the actual problem.

Excavation & void removal

We dig out the loose, unstable soil and fill material until we reach competent ground, removing the hidden void rather than capping it.

Engineered backfill & compaction

We rebuild the subsurface in controlled lifts with structural fill, compacting each layer so the repaired ground supports loads and does not settle again.

Drainage correction

We redirect surface and subsurface water away from the repaired area with grading, swales, French drains or solid pipe so the conditions that caused the sinkhole do not return.

A stable, rebuilt surface and a water route that keeps the ground solid — no more watching the yard disappear after a rain.

How it goes

Our process

Step 01
Inspect
Map the depression, check for utilities, and identify where water is entering the ground.
Step 02
Excavate
Remove unstable fill and expose the full extent of the void.
Step 03
Rebuild
Backfill in compacted lifts with the right material for the depth and loading.
Step 04
Divert water
Correct grading and drainage so the repair stays solid.
