Aggregate Products & Gravel in St Tammany County, Louisiana

Sand, Soil, and Specialty Materials

Sand and soil selection matters in St. Tammany County because local soils range from sandy loam near Lake Pontchartrain to more clayey, alluvial soils along river corridors. Choosing the right material can reduce maintenance and improve drainage.

Topsoil and fill options

Use screened Topsoil for lawn seeding and garden beds where organic content and texture matter. For grading, basements, or raised pads choose Fill Dirt that compacts well and reduces settlement.

Sands for construction and play

• Mason Sand - masonry and finish work
• Washed Sand - clean material for concrete and bedding
• Playground Sand - safe surfacing for schools and parks

Decorative Rock & Erosion Control

Properties in St. Tammany County benefit from both functional and decorative rock. From protecting shorelines near Lake Pontchartrain to highlighting garden entries, rock choices matter.

Decorative and functional rock types

• River Rock - rounded stones for beds and shoreline stabilization
• Pea Gravel - comfortable walking surface and decorative mulch substitute
• Decomposed Granite - natural-looking paths that compact and drain

Erosion control and drainage

For properties with runoff or high groundwater, pair Drain Rock with geotextiles to build effective French drains. In many coastal and river-adjacent yards, combining river rock beds with native plantings stabilizes soil and improves storm resilience.

Driveways, Roads, and Heavy Duty Aggregates

St. Tammany County sees a mix of suburban driveways and rural roads. We supply materials designed to perform in wet climates while providing good traction and long-term durability.

Materials for strong driveways

• Driveway Gravel - blended for wear and drainage
• 3/4 inch Crushed Stone - used for base and surface courses
• Crusher Run - excellent compaction and load distribution

Road base and recycled options

For private lanes and commercial pads, choose Road Base. When sustainability is a goal, Crushed Concrete provides a cost-effective, recycled alternative that performs well if compacted correctly.

Local Soil, Climate, and Construction Considerations

St. Tammany County sits in the Gulf Coastal Plain with a humid subtropical climate. Summers are hot and humid, winters mild, and annual rainfall is relatively high. These conditions shape how aggregates perform.

Soil and geology

Near Lake Pontchartrain and along river floodplains you will find sandy loam and alluvial deposits that drain relatively well. Inland and in low-lying marshy spots, finer clays and organic soils can hold moisture. Using well-draining aggregates like #57 stone and drain rock helps prevent rutting and pooling.

Climate impacts and best practices

• High rainfall means effective drainage is essential on driveways and around foundations
• Hurricane season increases the need for erosion control and stable surfacing
• Salt exposure near bayous and the lake can affect certain decorative materials

Regional construction trends

Locally, contractors favor recycled materials like crushed concrete for subbases to meet sustainability goals. Decorative pebbles and river rock are popular in Mandeville and Covington yards for low-maintenance designs that withstand storms.

Ordering Process and Tips

How to estimate quantities

Estimate cubic yards for loose materials and tons for denser stone. Our team can calculate quantities—tell us your area dimensions and desired depth and we'll recommend a load size. For gravel driveways, 3 to 4 inches compacted is common; for base layers plan for larger depths.

Delivery and site access

We accommodate narrow drives and will discuss staging areas to minimize property disturbance. For deliveries near wetlands or flood-prone yards, we advise on placement to avoid washout during heavy rains.

Local regulations and permits

Certain projects near lakefronts or rivers may require permits. We recommend checking with St. Tammany Parish planning departments in Covington or Slidell prior to large-scale changes near shoreline or wetland areas.
