Drainage, Erosion Control & Landscaping Rock

St. Louis County properties often need targeted drainage solutions because of clay subsoils and low-lying stream valley areas. Proper aggregates keep water moving away from foundations and reduce erosion on slopes.

Drain Rock and #57 Stone

Use drain rock or #57 stone in trenches, around perforated pipes, and in French drains for consistent water flow. Clean, angular aggregates prevent clogging and settle into durable drainage channels.

Decorative River Rock and Pea Gravel

For landscape beds and decorative borders choose river rock or pea gravel. River rock is excellent for water features and riparian buffers, while pea gravel is comfortable underfoot for patios and playground surrounds.

• Drainage applications: drain rock, #57 stone
• Decor: river rock, pea gravel, decomposed granite
• Erosion control: larger river rock in channels and rip rap

Sand, Soil & Play Areas

Sand and soil types play a big role in plant health and play area safety across the county. We deliver screened topsoil and several sand types to meet municipal and homeowner needs.

Topsoil and Fill Dirt

Use topsoil for planting, lawn establishment, and repair after construction. For leveling or infill, order fill dirt that compacts predictably under the local clay subgrade.

Sands for Bedding and Play

We supply mason sand, washed sand, and playground sand for paver bedding, mortar mixing, and safety surfacing for community parks.

• Topsoil for lawns and gardens
• Fill dirt for grading and structural fills
• Washed sand and mason sand for pavers and masonry work

Recycled, Decorative & Specialty Aggregates

To support sustainable projects and specialty finishes we offer recycled materials and decorative aggregates that match local design trends.

Crushed Concrete and Sustainable Options

Crushed concrete is a cost-effective, eco-friendly alternative for sub-base layers, driveways, and parking pads. It performs well in areas with moderate freeze-thaw when properly compacted.

Decomposed Granite and Walkway Gravel

For low-maintenance garden paths, use decomposed granite or walkway gravel. These aggregates yield stable walking surfaces that echo regional design preferences in many St. Louis County neighborhoods.

• Sustainable: crushed concrete
• Decorative: decomposed granite and river rock
• Soft surfaces: pea gravel and playground sand

Project Types and Material Recommendations

Different projects in St. Louis County call for specific aggregates. Below are common project types and recommended materials suited to county conditions and common soil profiles.

Residential Driveways

For new driveways, begin with road base or crusher run for the sub-base, then top with driveway gravel or 3/4 inch crushed stone for surface durability. Proper drainage using drain rock at edges drastically reduces potholing on clay soils.

French Drains and Erosion Control

Use #57 stone or drain rock to enable clear water flow around foundations and through stormwater channels. Add geotextile fabric to separate soil and stone for long-term performance.

Patios, Walkways & Garden Paths

For paths, decomposed granite and walkway gravel provide ADA-friendly textures and a natural look popular in many county neighborhoods.

• Driveways: road base, crusher run, 3/4 inch crushed stone
• Drainage: #57 stone, drain rock
• Walkways: decomposed granite, walkway gravel

Local Soil, Climate & Geology Considerations

Understanding St. Louis County geology helps select the right aggregates. The county sits over glacial and river-deposited soils with clayey loam in many suburban lots and alluvial deposits along the Missouri and Meramec Rivers. These soils affect drainage, compaction, and frost heave.

Soil Types and Drainage

Clay-rich soils common in the county retain water and reduce percolation. That makes using free-draining aggregates like #57 stone and drain rock essential for foundation drains and low-lying yards.

Freeze-Thaw and Seasonal Considerations

St. Louis County experiences cold winters with occasional deep freezes and spring thaw cycles. Use compactable base materials such as crusher run and properly graded road base to reduce frost heave and surface shifting.

Regional Trends and Permitting

Many neighborhoods prefer natural rock finishes and permeable surfaces to reduce runoff. For larger projects, check county stormwater regulations and HOA guidelines before finalizing materials.
