FAQ

What should I put down on a muddy driveway?

Dense-graded base (Dense Pack) compacted over soft spots, topped with 3/4-inch stone. Quick fix: 2–3 inches of 3/4-inch crushed granite.

Do you deliver to Cambridge, MA?

Yes — all of Cambridge is a flat $100 per truckload. Triple-deckers and tight access are routine; add notes and a photo at checkout.

Do you offer Net-30 terms for contractors?

Yes — established commercial accounts get Net-30 terms with PO-tracked invoicing. Apply via the contractor form or email sales@ottrsupply.com.

How do I measure my driveway for gravel?

Multiply length by width in feet, then (sq ft × depth in inches) ÷ 324. A 12×50 ft driveway at 3 inches needs 5.6 — order 6 cubic yards.

Can I use mason sand for winter traction?

Yes — washed, angular mason sand grips ice well for winter traction. Want melting too? A premixed salt-sand blend does both in one pass.

Does frozen ground affect bulk material delivery?

Mostly no — driveway and curbside drops run as normal all winter. Hard frost can delay on-property lawn drops, and winter is the easiest season to book.
