Sobre Este Material

A gravel driveway is one of the most affordable and practical alternatives to poured concrete or asphalt. When properly installed with the correct materials and adequate depth, a gravel driveway can last 10 to 15 years with minimal maintenance. The best gravel driveway is built in three layers. The bottom layer (4 inches) uses large #3 or #4 stone (1.5 to 3 inches) for drainage and stability. The middle layer (4 inches) uses #57 stone (3/4 inch) as a transition. The top layer (2 to 4 inches) uses compactable stone like #8 or #411 that locks together to form a firm driving surface. Each layer must be spread and compacted separately. Crushed stone (#57 or #411) is the most popular driveway gravel because its angular edges lock together under compaction, creating a stable surface. Road base (also called crusher run or #21A) is a blend of crushed stone and stone dust that compacts into an extremely hard surface — it is the preferred choice for heavy-traffic driveways. Pea gravel looks attractive but shifts under tires and is not recommended as a primary driveway surface. Decomposed granite compacts well and provides a natural appearance, popular in the western United States. Driveway gravel costs $1 to $3 per square foot installed, depending on depth and material. A typical 12x50-foot single-car gravel driveway costs $600 to $1,800 for materials only. Professional installation with grading, fabric, and compaction adds $2 to $5 per square foot. Annual maintenance includes raking displaced stone back into ruts and adding a 1 to 2-inch top-up layer every 2 to 3 years.

Consejos de Instalación

• •Grade the driveway with a 2 to 3% slope away from the house for proper drainage — water pooling on gravel creates potholes.
• •Install geotextile landscape fabric over the graded subgrade to prevent stone from mixing with the soil below.
• •Spread and compact each layer separately — do not dump all the gravel at once.
• •Use a plate compactor or roller on each lift to maximize density and stability.
• •Install border edging (steel, aluminum, or timber) along both sides to prevent gravel migration into the yard.
• •Crown the driveway center slightly higher (1 to 2 inches) so water sheds to both edges.

Errores Comunes a Evitar

• ⚠Using pea gravel as the driving surface — its rounded shape does not compact and stones scatter under tires.
• ⚠Dumping gravel directly on topsoil without grading — organic soil decomposes and causes sinkholes and mud mixing.
• ⚠Applying only 2 to 3 inches of gravel — this is too thin for vehicle traffic and will rut through to the subgrade quickly.
• ⚠Skipping the fabric layer — without it, gravel sinks into soft soil within 1 to 2 years and you lose half your stone.
• ⚠Not compacting between layers — loose gravel shifts and develops ruts and potholes within weeks of use.
