Understanding Gravel

Gravel Sizes & Uses

Fine Gravel (1/4" - 1/2")

Pathways, decorative areas, drainage around foundations.

Medium Gravel (1/2" - 3/4")

Driveways, parking areas, general construction base.

Coarse Gravel (3/4" - 1.5")

Heavy-duty driveways, road base, drainage systems.

Decorative Stone (Various)

Landscaping, garden beds, water features.

Installation Guidelines

Base Preparation

Excavate to proper depth, compact soil, install landscape fabric if needed.

Gravel Installation

Spread evenly, rake to level, compact in layers for driveways.

Edging & Borders

Install edging to contain gravel and maintain clean lines.

Maintenance Tips

Regular Maintenance

Rake to redistribute, add material as needed, control weeds.

Seasonal Care

Spring raking, summer weed control, winter snow removal.

Drainage

Ensure proper slope for water runoff, clear drainage channels.

Replenishment

Add new gravel every 2-3 years or as needed for high-traffic areas.

Frequently Asked Questions

How deep should gravel be for a driveway?

Typically 3-4 inches for residential driveways, 4-6 inches for heavy vehicle access. Consider local climate and soil conditions.

What's the difference between crushed stone and gravel?

Crushed stone has angular edges and compacts better for structural applications. Natural gravel is rounded and better for drainage and decorative uses.

Do I need landscape fabric under gravel?

Yes for decorative applications to prevent weeds. For driveways, use geotextile fabric over soft soils to prevent mixing with subgrade.

How much does gravel compact?

Gravel typically compacts 10-15% depending on type and installation method. Order extra material to account for compaction and settling.
