Why houses move in Gainesville

Much of Gainesville sits on about five feet of sand over clay-rich soil, with limestone below that water slowly dissolves. Heavy summer storms soak the sand and wash it down into gaps in the rock. That is why the county sees sinkholes and settling under both old homes near downtown and newer slab homes on the west side.

  • Slabs with some age

    Half of the homes in Gainesville were built before about 1985, according to Census data. Most slabs crack a little as they age. Tile laid over them shows those cracks first.

  • Sand under the slab

    USDA describes common local soils as several feet of sand over a clay-rich layer. Sand that packs down or washes out under one part of a slab leaves that part unsupported, and it cracks.

  • Leaks wash out sand

    Alachua County lists leaking water and sewer pipes as a cause of the ground settling. In a slab home, those pipes run under the floor.

What you will notice

Tile is hard and thin. It cannot stretch. When the concrete under it moves even a hair, the tile tells you.

One straight crack

Running across several tiles in a row.

A crack that crosses the room

From one wall toward the other.

Tiles that pop up

Or tent at the grout line.

Hollow sound

When you tap a tile with a coin or a key.

Grout that keeps cracking

In the same line after you fix it.

Tile that is higher on one side

Of a crack than the other.

A crack that lines up

With a crack in the wall or a door that sticks.

Tile problem or slab problem?

There are two kinds of cracked tile.

A tile problem. The tile cracked on its own. Something heavy got dropped. The thinset under it was thin or patchy. The tile was laid with no gap at the walls, so it had no room to move with heat. These cracks show up on one or two tiles, often in random spots.

A slab problem. The concrete under the tile cracked, and the tile cracked with it. These cracks run in a line across many tiles. They tend to get longer over time. The two sides of the crack may end up at different heights.

Inch Calculator notes that many broken tiles can point to an unstable surface underneath. That is the clue to look for. A line, not a scatter.

Why slabs crack under tile here

Most slabs crack a little. Concrete shrinks as it cures, and hairline cracks are common. Those do not always mean anything.

The ones that matter in Gainesville come from the ground under the slab.

Settling sand

USDA soil surveys show many yards here have several feet of sand over clay. Wet sand can pack down under part of the slab.

Sand that drains away

Water can carry sand into gaps in the limestone below. Alachua County says sinking is most common in very wet spells after dry ones.

Leaking pipes

Water and sewer lines run under the slab. A leak can wash out the sand beneath it.

Buried debris

The county lists scrap wood and roots left in the fill as a cause of settling, as they rot.

Water at the edge

A downspout that dumps next to the house soaks the sand under the slab edge.

Half of Gainesville's homes were built before about 1985. Many slabs have had decades of wet summers to move.

Cosmetic or urgent?

Usually cosmetic

  • One or two cracked tiles in random spots.
  • A hairline crack that has not grown in years.
  • A cracked tile where something heavy was dropped.

Get it checked soon

  • A crack running through three or more tiles in a line.
  • A crack that gets longer every few months.
  • One side of the crack higher than the other.
  • Tile cracks along with sticking doors or wall cracks in the same area.
  • A crack with warm spots, damp grout or a jump in your water bill.

What the fix usually is

If the slab is stable, the fix is just tile work. Remove the cracked pieces and set new ones. Inch Calculator puts a tile or two at about $100 and a typical tile repair at $250 to $700. Keep spare tiles from the original job if you have them. Matching old tile is often the hardest part.

If the slab has dropped, new tile alone will crack again. The crew first supports the low area, often with steel piers set under the slab edge. Fixr puts piers at about $1,000 to $3,000 each. Then the tile is replaced once the slab stops moving. See slab foundation repair.

If a leak is the cause, a plumber finds and fixes it first. A pressure test on the drain lines under the slab is a common way to find one.

What to do before the inspection

  1. Draw a rough map of the room and mark where each crack runs.
  2. Mark the ends of the crack in the grout with a pencil and the date.
  3. Tap nearby tiles. Note which ones sound hollow.
  4. Check your water bill for any jump in the last few months.
  5. Look for cracks in walls or stucco that line up with the floor crack.
  6. Hold off on new tile until you know what is under the old one.

Frequently asked questions

Does a cracked tile mean my foundation is failing?

Not by itself. Most slabs have small cracks, and tile laid right over them can crack too. A line of cracked tiles that keeps getting longer, or tile cracks with sticking doors, is the kind to check.

Why do my tiles sound hollow when I tap them?

The tile has come loose from the slab. Weak thinset, a slab that was not clean, or a slab moving a little under it can all do that. Hollow tiles crack more easily.

Can I replace just the cracked tiles?

Yes, if you have spares and the slab under them is stable. Inch Calculator puts swapping a tile or two at around $100. If the crack in the slab is still moving, new tile will crack again in the same line.

Can a plumbing leak crack my tile?

It can. A leak under the slab can wash out the sand below it, and the slab above can drop and crack. Warm spots on the floor, the sound of running water or a high water bill are clues.

Should I fix the tile before I sell?

A buyer's inspector will notice a line of cracked tile and ask why. It helps to know the cause first. A cracked slab with a written report and repair is easier to explain than new tile over an old crack.
