Sioux City Demolition Pros connects Sioux City owners with local crews who fill in basements, whether the house above has just been torn down or an old foundation was left open. Most older houses in the city have full basements with brick or rubble walls, and the hole they leave is the largest single part of a house demolition after the building itself.
Filling a basement properly at $3,000 to $5,000 leaves a level, buildable lot, while loose fill dumped in to save money settles into a sinkhole that has to be dug out and refilled, paying for the same $3 to $6 per cubic yard backfill twice.
How a basement is filled in Sioux City
The walls are broken down or pushed in below grade, the floor is broken or drilled so water drains through it, and the hole is filled in layers and compacted. Sioux City's code makes the fill part of the demolition: the excavation must be filled so that it poses no danger, and the city's grading standards set how.
- Walls collapsed or removed below grade.
- Floor broken so the hole cannot hold water.
- Fill in layers no thicker than eight inches, compacted as it goes.
- Topsoil and seed or another ground cover on top.
What the fill-in costs, and what changes it
$3,000 to $5,000
To break out and fill a 1,000 square foot basement at HomeGuide's $3 to $5 per square foot basement removal rate; tractor backfilling runs $3 to $6 per cubic yard. No guide publishes a single fill-in figure, so this is the stated arithmetic.
Call (712) 543-5529The volume of the basement sets the amount of fill, and trucked-in fill is the bulk of the cost. Whether the walls are removed or collapsed in place, how far the fill travels and whether the lot will carry a new building next all change the price. Moving more than 50 cubic yards needs a city grading permit, which most house basements do.
Fill material and compaction rules
The city's grading ordinance wants fill from approved sources, free of vegetation, broken concrete, asphalt and large rocks unless the approved plan allows them, compacted to 90 percent standard proctor by default. Fill placed with no plan for a building may be compacted to 85 percent, but only if the owner signs that the site is not ready for construction without soil testing. Fill deeper than five feet needs an addendum recorded with the county.
Loess, frost and timing the final grade
Loess soil is easily eroded and can slump when wet, so the finished grade is crowned slightly to shed water. Fill cannot go in on frozen or thawing ground, and the city wants ground cover within 30 days of finishing, or by April 1 if the work ends after October 1. Fall jobs often finish with a spring seeding.

Frequently asked questions
Basement fill-in in Sioux City, answered
How much does it cost to fill in a basement in Sioux City?
For a 1,000 square foot basement, breaking it out and filling it at HomeGuide's $3 to $5 per square foot basement rate comes to about $3,000 to $5,000. Fill hauled a long distance or compacted for a future building costs more.
How do you backfill a basement so it does not settle?
In compacted layers no thicker than eight inches, with the floor broken so water drains, and topsoil on top. Loose, dumped fill is what causes the hollow that shows up a year later.
What are the signs a filled basement was done badly?
A sunken patch in the lawn shaped like the old house, standing water after rain and debris working up through the soil. It usually means loose fill or buried trash.
Do I need a permit to fill in a basement in Sioux City?
The fill is part of the demolition permit, and a separate grading permit applies once more than 50 cubic yards are moved, which a typical house basement exceeds.
Can I build on a filled basement later?
Yes, if the fill was placed and compacted for it. Tell the contractor at the start, because fill compacted for lawn is held to a lower standard and needs soil testing before construction.
