Granite Concrete has been supplying ready-mix concrete to Libby, MT and Lincoln County since 1965, and now supplies the Bitterroot Valley from our Corvallis location. Whether you’re pouring a driveway, setting footings, building a retaining wall, or placing columns, getting your estimate right before you order saves time and money on the job. Use the concrete calculator that our customers rely on to get accurate material estimates before you call.
How to Use the Concrete Calculator
Enter your dimensions in feet and inches for the shape you’re working with: slab, wall, or circular column. The calculator gives you a cubic yard estimate you can use when placing your order. If you’re not sure which form fits your project, call us: Libby and Lincoln County at 406.293.3777 or Corvallis and the Bitterroot Valley at 406.802.0567, and we’ll help you figure it out.
What We Supply
Granite Concrete produces ready-mix concrete for residential, commercial, and specialty applications across Lincoln County and the Bitterroot Valley. Our fleet includes a pump truck for efficient placement on jobs where direct chute delivery isn’t practical. Libby projects have direct access to this equipment; Corvallis orders are delivered by mixer and conveyor. Contact us to discuss the right setup for your project. We offer a variety of mix designs to meet project specifications, from standard residential mixes to engineered mixes for specific load requirements.
If you’re working on a larger project and need aggregate or precast concrete products in addition to ready-mix, we supply those from our Libby location. Visit our Products page for the full list.
