Applications
Common uses for Spillway Dirt
Spillway dirt serves one primary purpose: raising elevation in low-lying areas where massive volume is required and long-term stability is non-negotiable. This is the material of choice for South Louisiana property owners fighting subsidence, building above flood levels, and creating permanent elevation solutions.
Material applications
Flood Protection Berms
Build protective berms around properties and water diversion structures that withstand storm surge.
Subsidence Repair
Fill large subsidence-damaged areas where yards have dropped 3-6 inches over 5-10 years.
Commercial Site Development
Raise elevation for commercial properties and industrial yards before construction begins.
Building Pads
Create elevated building pads raising foundation level 3-6 feet above existing grade.
Rural Property Development
Create homesites on historically wet property and establish agricultural fields above flooding.
Local performance
Why Spillway Dirt works here
Local conditions.
New Orleans faces unique elevation challenges unlike anywhere else in America. The city subsides 1-3 inches per decade in many areas, sits below sea level, and experiences regular flooding. Spillway dirt has been the workhorse material for fighting this elevation crisis for over a century,the same material used to build and maintain Bonnet Carré Spillway, Morganza Spillway, and countless levee systems throughout South Louisiana. This material's proven performance gives property owners confidence in its long-term stability.
- Small projects under 20 yards (benefits don't justify sourcing)
- Areas requiring excellent drainage without drainage systems
- Garden beds and planting areas (wrong material entirely)
- Projects lacking proper compaction equipment
- Quick timeline projects (requires methodical multi-day installation)
Built for New Orleans
Use spillway dirt for major elevation and flood protection projects. This is strategic material for serious elevation projects, not casual landscaping. For whole-property elevation projects, plan installation carefully. Survey existing grade to identify low points and establish target elevation based on FEMA flood maps or flood insurance requirements. Install in 6-8 inch lifts, compacting each lift with plate compactor or roller before adding next layer. This layered approach prevents the massive settling that occurs when contractors dump 24 inches all at once.
- Raising entire properties above flood elevation
- Creating substantial berms and flood barriers
- Filling large subsidence-damaged areas
- Commercial and industrial site development
- Creating building pads for elevated structures
- Rural property development and land reclamation

Before you order
Check the site access.
Not every property can accommodate a standard dump truck. Here is what you should check before scheduling delivery.
Street width
Standard trucks need roughly 10 to 12 feet of clear access.
Overhead clearance
Power lines and branches must clear the raised dump bed.
Ground stability
The truck needs firm ground for entry, placement, and exit.
Dump location
Have the exact placement area ready before the truck arrives.
Material delivery notes
Confirm project requires massive volume (30+ yards minimum)
Plan for professional installation with proper compaction equipment on large projects
Calculate needs with 15-20% settling allowance
Verify truck access for multi-truckload deliveries
Schedule around weather for multi-day installation (5-7 day dry window)
Plan drainage solutions,material won't drain itself
Budget for 4-6 inch topsoil cap on all landscaped areas
Delivery and placement
Details before the truck arrives.
Load sizes
Spillway dirt projects typically require large volumes,30+ yards minimum, often 50-200+ yards. Full truckload deliveries reduce per-yard costs significantly.
Truck types
Standard dump trucks for open sites. Large projects may require staging delivery over 2-3 days to allow spreading and compaction between loads.
Placement options
Driveway or street-side for multiple truckloads. Material may need staging area for large multi-day projects.
Access verification
Confirm property can accommodate repeated truck access. Our trucks need 30+ feet straight approach, 10-12 feet width, stable ground for repeated trips.

SpecificationProject note
Clay Content & Composition
35-50% Clay Content
Higher than standard fill dirt's 20-40% but not as extreme as pure clay dirt. This moderate-to-high clay content provides excellent compaction while remaining more workable than pure clay dirt.
Compaction & Load-Bearing
92-95% Maximum Density
Creates load-bearing capacity of 2,000-2,500 lbs per square foot,adequate for residential structures, light commercial buildings, and most typical applications when properly compacted.
Settlement Characteristics
8-12% Settling Expected
Slightly more than standard fill dirt but significantly less than high-organic materials. Install to 10-15% above desired final grade, allow 4-8 weeks for initial settling, then top to final grade.
Moisture Sensitivity
Optimal at 15-20% Moisture
At optimal moisture, material is firm, workable, and compacts excellently. Above 25% it becomes sticky; below 12% it won't compact adequately. Poor natural drainage requires topsoil cap for any landscaping.

Questions About Spillway Dirt
Questions about Spillway Dirt.
Spillway dirt typically ranges from $18-28 per cubic yard,economical for large-volume elevation projects while costing slightly more than basic fill dirt due to material sourcing and higher clay content. Total project cost including delivery, equipment rental/professional installation, and topsoil cap typically runs $30-45 per installed yard.
Calculate using: (Property square footage × Elevation gain in inches) ÷ 324 = cubic yards, then add 15-20% for compaction and settling. Example: Raising 2,500 sq ft by 18 inches = 139 yards + 18% = 164 yards total. This doesn't include topsoil cap,add 4-6 inches calculated separately.
Spillway dirt comes from Mississippi River spillway excavations and typically contains 35-50% clay versus standard fill dirt's 20-40%. This provides superior compaction (92-95% density versus 90-92%) and proven long-term stability from decades of performance in Louisiana's spillway infrastructure.
Spillway dirt is excellent for creating elevated building pads when properly compacted. However, actual foundation construction (footings, slabs, structural supports) requires engineering specifications. Spillway dirt creates the elevated platform; additional materials create the foundation structure itself.
If material arrives at optimal moisture (forms ball when squeezed, breaks with light pressure), you can begin immediately. If too wet after rain, allow 2-4 days drying. If too dry during drought, add water and allow 6-12 hours for moisture to distribute. Never work spillway dirt when sticky wet.
Spillway dirt raises your property elevation, which can move you above flood levels and into lower-risk flood zones for insurance. However, elevation alone doesn't prevent all flooding,surface drainage must be properly designed to move rainwater off the property. Combine elevation with proper final grade (2-3% slope away from structures).
