Why is Drain Rock the best for this project?
Drain rock beats pea gravel and crushed limestone for French drains. Larger voids, better long-term flow.
Are there cheaper alternatives?
Yes - but the cost difference is usually $1-5 per ton, while the wrong material can double your install time. Pick Drain Rock unless your local quarry doesn't carry it.
How much do I need?
Depends on area and depth. A typical residential project needs 2-6 tons. Use the linked calculator for exact tonnage.
Can I install it myself?
Yes - most homeowners spread Drain Rock with a wheelbarrow, rake, and plate compactor over a weekend.
How long does it last?
Properly installed, 10+ years before any top-up is needed. UV doesn't break down rock.
Where do I buy it?
Order from us - bulk delivery same-day in most metros. Or buy bagged at home centers for small jobs.
