Fill Dirt in Midvale, UT

Fill-dirt is subsoil material (mostly mineral soil with little organic matter) used to raise grade, backfill trenches, create building pads, or fix drainage. In Midvale it’s commonly used to level yards, build up low spots in lots near the Wasatch Front, and provide a stable base for patios, sheds, and driveways.

Salt Lake Valley soils, including Midvale, tend to be neutral to slightly alkaline because of local mineral content, which affects plant growth if you plan to topdress with topsoil. If you plan to use fill-dirt under a planting bed, test the site pH first and put a layer of topsoil or amended soil over the fill before planting to give plants the right nutrients and pH.

Fill-dirt is mostly mineral subsoil with low organic matter and is intended for grading and structural fill; topsoil is nutrient-rich surface soil used for planting. For raising grade or backfilling you want fill-dirt; if you are planting lawn or beds add a 4-6 inch layer of topsoil on top for plant health.

You can cover grass with fill-dirt, but it will smother and kill the grass; remove turf first if you want a clean installation. If you must place fill quickly, put fill in thin layers and compact as needed, then plan to add topsoil and reseed or sod for a healthy lawn.

Clear vegetation and debris, call 811 to locate underground utilities, flag important lines, and confirm desired grades and drainage. Also decide on compaction method and sequence (place fill in lifts and compact each layer) and check local Midvale or Salt Lake County permitting if you’re changing lot elevations significantly.

Keep delivered fill-dirt covered with a tarp if you need to store it to prevent erosion, contamination, and excessive drying. Place piles on a stable surface away from drainage paths, avoid driving heavy equipment over stored material to limit contamination, and use it within a few months to avoid weed growth and compaction.

Calculate volume in cubic yards: area (sq ft) x depth (ft) / 27 equals cubic yards, then convert to tons using your supplier's density. Example: raising 1,000 sq ft by 3 inches needs about 9.3 cubic yards; check with Hello Gravel on tons and remember our minimum order is 3 tons.

One cubic yard is about 27 cubic feet, which is roughly 40 five-gallon buckets of material. Because fill-dirt density varies, that works out to roughly 30 to 32 five-gallon buckets per ton for typical fill-dirt used around Midvale.

Adding small amounts of coffee grounds or cinnamon to bulk fill-dirt won't meaningfully change pH or fertility for large projects. For planting, it's better to amend the topsoil layer with compost and balanced amendments rather than trying to treat bulk fill-dirt with kitchen scraps.

Green coloration is usually surface algae or moss from moisture, or mineral staining from local materials; it is often harmless for non-planting uses. If the fill-dirt comes from an industrial site or you see unusual odors or residues, test the soil and contact local environmental authorities before using it in residential landscaping.

Prices vary by source, delivery distance, and market conditions, but fill-dirt in the Salt Lake Valley often falls in a conservative range of about $10 to $30 per ton (or roughly $8 to $25 per cubic yard). Final cost depends on minimum order (Hello Gravel requires 3 tons), delivery type, and any spreading or access challenges.

Yes, fill-dirt should be placed in thin lifts (4-8 inches), moistened if too dry, and mechanically compacted with a plate compactor or roller for stable results. In Midvale's dry climate you may need to add a little moisture before compaction, and avoid compacting frozen ground or during heavy rain.

Small residential grading projects often don't require a permit, but raising lot grades, adding more than a few inches across large areas, or altering drainage can trigger city or county permits. Check with the City of Midvale and Salt Lake County planning or public works before large fills, and always call 811 before digging.
