Gravel in Knoxville, TN

Typical Knoxville price ranges (estimates) - check Hello Gravel for live rates: per ton: about $15 - $45 depending on type (pea, crushed limestone, bank run); per cubic yard: about $20 - $60. Final price depends on material type, supplier, delivery distance, and minimum-order fees.

Approximate coverage using a typical conversion of 1 ton ≈ 0.7 cubic yards (actual varies by material): 1" depth - about 225 sq ft; 2" depth - about 113 sq ft; 3" depth - about 75 sq ft. Use the formula: sq ft covered = (tons * 0.7 yd3/ton * 324) / depth_in_inches.

Quick conversion rules (approximate): 1 cubic yard ≈ 1.35 - 1.5 tons for common crushed gravel - use 1.4 tons/yd3 as a guideline. So 1 ton ≈ 0.7 cubic yards. 1 cubic yard ≈ 201.97 gallons, so about 40.4 five-gallon buckets per cubic yard. That means roughly 28 five-gallon buckets per ton (0.7 * 40.4). Exact numbers vary by material density and moisture.

Common dump truck sizes: small pickup/dump trailer 1-3 yd3, contractors 6-10 yd3, 10-14 yd3 standard, large 20-25 yd3. Example coverage (using yd3*324/depth_in_inches): 10 yd3 covers about 3" - 1080 sq ft, 2" - 1620 sq ft, 4" - 810 sq ft. Weight of a 10-yd3 load at 1.4 tons/yd3 ≈ 14 tons. Confirm truck size and weight limits with the supplier.

For Knoxville's rainy and occasional freeze-thaw conditions choose an angular, crushed stone base and a coarse surface: - Base: 3/4" crushed stone (or #57) compacted 4"-6" for residential drives - Surfacing: 3/8" to 1/2" crushed stone, crushed limestone, or 'crusher run' for a lock-together surface. Avoid loose round pea gravel for high-traffic driveways - it moves and rutts. Proper drainage and compaction are more important than the exact aggregate.

Recommended compacted depths: - Walkways: 2"-3" of surface gravel over 2" of compacted base or fabric - Residential driveway (light traffic): 4"-6" total compacted (4" base + 1"-2" surface) - Driveway (regular cars, moderate use): 6" total - Heavy vehicles or commercial: 8" or more with a structural base. For Knoxville, prioritize a compacted base and good drainage to handle wet seasons.

Best value options: - Bank run gravel or screened crushed stone - economical for base layers - Crushed limestone - widely available in TN and good for bind and compaction - #57 crushed stone - good for top surface and drainage Cheaper options like recycled concrete can be economical but check fines and compaction characteristics. Consider long-term maintenance - a slightly higher-quality angular crushed stone will reduce regrading and top-ups.

Formula: cubic yards = (area_sqft * depth_inches) / 324. Example for 1,000 sq ft: - 1" depth: 1000/324 ≈ 3.1 yd3 - 2" depth: ≈ 6.2 yd3 - 3" depth: ≈ 9.3 yd3 Convert to tons using 1 yd3 ≈ 1.4 tons: multiply yd3 by 1.4. Always add 5%-10% for compaction and spillage.

Provide: delivery address with clear access notes, material type (example: 3/4" crushed limestone), desired depth and area (or exact dimensions), preferred dump location on site, desired delivery date/time window, and any weight or HOA restrictions. Ask the supplier about minimum order, yard/ton price, delivery fees, and whether the truck can offload where you need it.

Typically small residential deliveries do not require permits, but check local ordinances and HOA rules. Prepare the site: clear vegetation, mark underground utilities, provide a solid approach for the truck to avoid soft ground, and protect lawns if needed. If delivery will block the road or require street parking, contact city or county public works for guidance.

Preparation steps: - Excavate and grade to desired slope for drainage - Install geotextile fabric if subgrade is weak - Lay and compact a 3"-6" base of larger crushed stone - Compact base with plate compactor or roller - Add finish layer (1"-3") and compact again; rake to shape - Edge with timber or pavers to retain material For Knoxville, ensure surface slopes to drain away from structures to avoid freeze-thaw damage.

Maintenance tips: - Regrade and level ruts after winter rains - Add 1/2"-1" of new top gravel every 1-3 years depending on traffic - Periodic compaction helps stability - Keep vegetation trimmed; use weed fabric under gravel to reduce weeds - For dusty surfaces, occasional watering or adding finer fines can help suppress dust.

Mixing is common: - Base of larger crushed stone with a finer top layer (screenings or crusher-run) gives good compaction and surface. - Mixing pea gravel with crushed stone can improve looks but pea gravel will migrate. - Avoid excessive fines on the surface if you need drainage. Make sure mixed materials are applied in correct layer thicknesses.

Knoxville gets significant rainfall and seasonal freeze-thaw cycles. Use angular crushed stone for interlock and drainage, maintain slope for runoff, and provide a compacted base. Avoid materials that retain water or float in heavy rains. Good drainage prevents washouts and reduces need for frequent repairs.

Pricing factors: material type, quantity, distance, truck size, and offloading difficulty. Access issues that may add charges: narrow drives, overhead wires/branches, steep or soft approaches that require smaller trucks or manual handling. Tell Hello Gravel about any obstacles and ask about a curbside vs. placed dump fee.

Estimated 10-yd3 load cost range: roughly $300 - $700 depending on material and supplier - check Hello Gravel for exact quotes. Weight: 10 yd3 * ~1.4 tons/yd3 ≈ 14 tons (approximate). Local prices fluctuate, so request an instant quote.

Leftover options: - Save it for future top-ups or landscaping - Use as base for pavers, garden pathways, or drainage trenches - Donate or sell excess to neighbors or on local classifieds - Haul to a local recycling center or gravel pit if disposal is necessary - Ask the supplier if they accept returns or buybacks (policies vary).

Online calculators are good starting points. Always add a 5%-10% contingency for compaction, grading, and spillage. For irregular shapes, soggy sites, or heavy compaction needs, consider adding 10%-15%. When in doubt, get the supplier to confirm quantities based on your site dimensions.
