Florida sinkhole compaction grouting

Updated · Florida Sinkhole Compaction Grouting desk

Deep compaction grouting is the job when karst limestone under your Florida house needs to be stabilized.

A residential foundation is in spec. A plant, a hotel, or a commercial site is not.

Answer the two questions, then send the email you actually read.

Call me back

Two answers. A no stops the form.

Is this job in Florida?
Is this deep compaction grouting to stabilize karst limestone under a residential foundation?
I already have this

A geotechnical engineering firm or a specialized foundation stabilization contractor receives this callback. The address book is not sold.

Do this before you hire

Name the job before you name a company. The job is deep compaction grouting to stabilize karst limestone under a residential foundation in Florida. If that is the hire, continue. If you need a roofer, a painter, a well, or a hotel crew, answer no and leave.

Confirm the state, confirm the job, look at the slab, type the email you read, then press the button. Notes under “I already have this” do not unblock a no.

Say the job the way the firm hears it

On the callback, use one sentence. The house is in Florida, the ground under the foundation is karst limestone, and you want that limestone stabilized with deep compaction grouting. A homeowner, a household, or a residential community can say it when the building is a house.

Do not add paint, a dock, or plant equipment to the call. This desk forwards one job. Geotechnical engineering firms and specialized foundation stabilization contractors receive it. They do not receive your address book.

The five water management districts are created in section 373.069, Florida Statutes. Hernando County and Pasco County name the Southwest Florida Water Management District in the county sections in the dossier. Ask the firm which filing they will sign. This page does not file it.

Dossier

Each item is a rule this desk will name. The citation is the statute, county code, or water management district chapter the sentence comes from. None of these lines is a price, a permit this page will file, or a promise that a firm will take the house.

  1. Florida law defines a sinkhole as a landform created by subsidence of soil, sediment, or rock as groundwater dissolves the strata underneath, including collapse into voids in limestone or dolostone. Citation: § 627.706(2)(h), Florida Statutes (2026).
  2. In those sections, a professional engineer is a person as defined in section 471.005 with a bachelor’s degree or higher in engineering and sinkhole experience, and a professional geologist is a person as defined in section 492.102 with a bachelor’s degree or higher in geology or a related earth science and that same kind of experience. Citation: § 627.706(2)(f) and (g), Florida Statutes (2026).
  3. The professional engineer and the professional geologist perform the tests they judge sufficient to determine sinkhole loss or another cause, and the engineer recommends building stabilization and foundation repair. Citation: § 627.7072, Florida Statutes (2026).
  4. After that testing, the professional engineer or professional geologist issues a written report and certification to the insurer and the policyholder. Citation: § 627.7073(1), Florida Statutes (2026).
  5. When stabilization or foundation repairs for a verified sinkhole loss are finished, the engineer who monitored them reports the repairs and files that report, with the legal description and the owner’s name, with the clerk of court for recording. Citation: § 627.7073(3), Florida Statutes (2026).
  6. Florida is divided into the Northwest Florida, Suwannee River, St. Johns River, Southwest Florida, and South Florida water management districts. Their boundaries are in the same section. Citation: § 373.069(1)(a)–(e) and (2), Florida Statutes (2026).
  7. In Hernando County, new and existing sinkholes are reported to the county planning division, the sheriff’s office, and the Florida State Watch Office, and repaired in compliance with Southwest Florida Water Management District requirements and acceptable engineering standards. The ordinance does not name a grout method. Citation: Hernando County Code of Ordinances § 28-269.
  8. Hernando County prohibits new discharges of regulated substances or untreated stormwater into sinkholes, karst solution features, or drainage wells. Stormwater treated to chapter 62-330, Florida Administrative Code, standards is presumed allowable. Citation: Hernando County Code of Ordinances § 28-266.
  9. In unincorporated Pasco County, the geotechnical report is prepared by a professional geologist under chapter 492, Florida Statutes, and a professional engineer under chapter 471, Florida Statutes, or by a professional engineer with geotechnical experience. Citation: Pasco County Land Development Code § 807.4.
  10. If soil slumping or a sinkhole opens during Pasco County construction, the applicant notifies the county, Tampa Bay Water, and the Southwest Florida Water Management District. One listed procedure is to excavate and backfill or grout, as required, to fill the affected area. Citation: Pasco County Land Development Code § 807.5.
  11. Pasco County requires sinkhole backfill to be clean and of similar or lower permeability than the surrounding soil, and treats disposal of regulated substances, solid waste, or untreated stormwater in a sinkhole as a violation. Citation: Pasco County Land Development Code § 808.10.
  12. For discharges into karst features, Pasco County’s groundwater section presumes stormwater is allowed when treated to chapters 62-25 and 40D-4, Florida Administrative Code, as those chapters stood on December 29, 2011. Chapter 40D-4 is the Southwest Florida Water Management District chapter titled Individual Environmental Resource Permits. The county code pins that date. It does not say a house must hold a compaction-grouting permit. Citation: Chapter 40D-4, Florida Administrative Code.

Walk the house in this order

Walk once, in daylight, before you send. Write what you see. Do not invent a cause. You are checking that the hire matches the house, not producing a report for a file.

  1. Sight along the slab. Note a drop, a gap, or a low corner.
  2. Open the doors on that side. Note a scrape or a missed latch, and the room.
  3. If a crack steps through block or brick, note the wall.
  4. If you are in a plant, a hotel, or a shop, answer no.
  5. Florida continues. Any other state stops the form.
  6. Stop if the lot is a Florida Panhandle deep clay zone or Everglades muck.
  7. Use an inbox you open. Add a phone only if you want a ring. The email alone sends.

Read the table before you press anything

The table is the limit of this desk. It is not a price list and not a set of reviews. An in-spec row may send. A refused row stops, even if another company would take the work.

Tampa, Ocala, Tallahassee, and Gainesville are not a refusal and not a page. A house there still sends when both answers are yes. Do not type a city into the address bar.

Where this Florida compaction grouting job is in spec
SituationWhat this desk does

Another stateRefused. Stop.

If you skip the stop

A clay crew, a muck crew, or a hotel crew is the wrong hire for this page. When the red box is on screen the email fields are gone. There is no second button.

If you are in spec and you close the tab, nothing is filed. Send while the answers are still yes.

Who is on the other end of the callback

You do not sign a contract here and you do not pay this page. A geotechnical engineering firm or a specialized foundation stabilization contractor receives the email. Scope and price belong to that conversation. This site prints no job price. Verify any number with them. If they decline, stop.

Do not ask for a named reviewer. The byline is the desk. The receiver is the firm. After the call, any agreement is between you and that firm. This page does not set the schedule.

Use the optional notes only for facts you already have

Open “I already have this” only when the fact is already in your hands. The callback sends either way.

  1. Say so if a Florida professional geologist or professional engineer already completed a boring report. The sinkhole-insurance report, when one exists, is the report in section 627.7073, Florida Statutes. Otherwise leave it blank. Do not invent a report number.
  2. Write a depth to limestone only if you were given one.
  3. Write the water management district only if you know it. The five districts are named in section 373.069, Florida Statutes. A district note is not a page.
  4. Describe cracked masonry, a slab drop, or a stuck door in a sentence or two.
  5. Write a distance to surface water or a spring only if you know it.

Do not hunt for a city page

This host covers Florida once. Tampa, Ocala, Tallahassee, Gainesville, and Orlando are not routes. Hernando County and Pasco County rules that this desk can cite are in the dossier, not on a second URL. Counties points at those citations, and you use the form here.

Compaction grouting is the service note. About says what the desk refuses and who receives a callback. Privacy says what is collected, where it goes, and that the address book is not sold.

Checklist for the send

Do these in order.

  1. Yes only if the house is in Florida.
  2. Yes only for deep compaction grouting under a residential foundation on karst limestone.
  3. Stop for Panhandle deep clay, Everglades muck, a plant, a hotel, or a commercial site.
  4. Send from a city with no page when both answers are yes.
  5. Type an email you read. Add a phone only to request a ring.
  6. Press the button and read the disclosure on the next line. Wait for the sent note. Do not switch to a mail program.

After the card says sent

Leave that inbox open. A call happens only if you typed a phone number. If the card says the callback could not be sent, wait and try once more. This host publishes no mailbox. The form is the only send.

If the email was wrong, send again and say so in the note. The firm may see both messages.

Questions owners ask

Does a Florida house qualify?

Yes, when you want deep compaction grouting to stabilize karst limestone under that residential foundation. A house is the building this job names. Answer yes on both questions and send the email.

Will Tampa, Ocala, Tallahassee, or Gainesville be refused?

No. Those cities do not get their own pages. They are not a reason to stop the form. If the house is in Florida and the job matches, send.

What if the lot is Panhandle clay or Everglades muck?

Stop. Florida Panhandle deep clay zones and Everglades muck areas are outside this job. Answer no. The email fields leave the card on purpose.

Who calls me back?

A geotechnical engineering firm or a specialized foundation stabilization contractor. The line under the button says the same thing. Your address book is not sold.

Do I need the limestone depth before I send?

No. Depth is an optional note. Leave it blank when you do not know it. The email still sends.

What if I have an email and no phone?

Send the email. No call-tracking number is published here. The email alone is enough. Add a phone only when you want a ring.
