When is the best time of year to order base material in St. Mary Parish?

Work runs year round here, because cold is not what limits it. Heavy rain and saturated clay are what stop a compaction pass, so the ground has to be dry enough to take the load. Order when the site has drained and the forecast is settled, and plan the delivery date at checkout around that window.

What is the difference between topsoil and fill dirt?

Topsoil is the growing layer for lawns, beds and grade repair. Select Fill is structural: it compacts rather than settling, so it raises low ground and builds a pad up out of the water, and it goes under a base course rather than under a lawn. Louisiana yards also list river silt and spillway dirt beside fill dirt as grade raising materials.

Q: What is 610 limestone and what is it used for in St. Mary Parish?

610 limestone is the dense graded Louisiana base size, also called #610, 610 base or CR610. It runs from stone dust up to about two inches, so the fines bind it and it hardens as it is rolled. It goes under driveways, parking pads, shed and building pads, and the compacted layer beneath flatwork.

Louisiana Rock Supply sells gravel, stone and aggregate delivery in St. Mary Parish, LA, and 610 limestone is the base the ground here asks for.

The parish sits on heavy alluvial clay that holds water and moves under a load.

That clay is why a pad or drive needs a compacted base course under it, not just a surface dressing. Order online and a dump truck tips the load on site.

Delivery across St. Mary Parish

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. Each product page has a calculator if you need to size the load.

A dump truck then tips the material in one pile at the delivery address. Bulk delivery reaches Morgan City, Franklin, Patterson, Berwick and Baldwin, along with the rest of the parish.

Because the truck tips one pile, plan where that pile should sit before the load arrives. The driver does not spread or place the material.

Start with the project, then pick the material. A driveway, a patio and a drain each want a different size and a different amount of fines.

610 limestone, the Louisiana base size

610 limestone, also called #610, 610 base or CR610, is the dense graded base size. It carries everything from stone dust up to about two inches, so the fines bind it and it hardens as it is rolled.

Louisiana DOTD specifies aggregate quality in Section 1003 of the Louisiana Standard Specifications for Roads and Bridges, with soundness and abrasion requirements in Subsection 1003.01. An aggregate source has to meet Section 1003 to be listed on the department's approved materials list.

The same 610 designation covers crushed limestone and recycled Portland cement concrete. Crushed concrete is not crushed quarry stone, so treat the two as separate products with the same size range.

Clean stone, sand and decorative rock

Where nothing has to compact, a clean stone does the work instead. #67 Stone is a little finer than #57 for drainage trenches, pipe bedding and concrete, and #4 Crushed Stone is a coarse clean stone for heavy drainage and very wet ground.

At the fine end, #8 Crushed Stone and #89 Crushed Stone bed pavers and fill paver joints, and Stone Screenings pack a path or a bedding layer.

For planting, Garden Soil suits raised beds, which matter here because the natural ground sits wet. River Rock covers beds and borders where nothing has to lock together.

Ground conditions across St. Mary Parish

Across the Mississippi and Red River alluvial plains, the ground is recent alluvium: silty clay and clay loam laid down by the rivers, deep, fertile and heavy. Sandier natural levee ridges run along the old channels, and backswamp clay sits in the low ground between them.

Two things follow from that. The water table sits high, and clay will not take water, so the land is flat and only the levee ridges drain by themselves.

The backswamp holds rain until it is pumped or ditched away.

An under-built base fails on that ground. A fines-bearing material placed over saturated clay has nowhere to send the water, which is why the base course and the drainage layer are separate decisions.

Erosion comes from river and bayou bank cutting, sheet flow across bare clay after a hard rain, and ditch and canal scour. Riprap is the angular stone for that work; rounded stone does not lock together and is not bank armour.

Work runs year round on this ground. Heavy rain and saturated clay, not cold, are what stop a compaction pass.

Choosing the right material

Assumption Parish sits on the deltaic plain, the marsh and the Chenier coast. Its ground is coastal marsh: organic muck and soft clay, under consolidated and highly compressible, with firm ground only on natural levee ridges, old distributary channels and the cheniers.

That is a real difference from St. Mary Parish, where the alluvium is mineral clay and silt rather than organic muck.

On marsh ground the drainage layer carries more of the load, and a base course over soft clay needs the water removed first.

Iberia Parish and St. Martin Parish share the same ground region as St.

Mary Parish, recent alluvium of silty clay and clay loam with levee ridges and backswamp between them. The ground is the same, and so is the material choice.
