Gravel Driveway and Regraveling Services in Corvallis, Montana

Expert Gravel Placement for Stronger Working Surfaces

Most gravel trouble is not a gravel shortage. Thin, muddy, washboarded drives almost always trace back to the wrong stone laid without a real base or proper compaction. At Bohlander Construction, we install and regravel driveways, roads, pads, and parking areas for rural homes and properties across Corvallis, Montana, building each surface exactly the way it should be built. We haul, place, grade, and compact material so it drains, grips underfoot, and holds its shape under daily use instead of scattering into ruts within months.


Getting there takes the right material in the right order. We supply and place base rock, crushed stone, and angular surface gravel, matching each layer so the finished drive locks together and sheds water. Worn surfaces are regraveled and regraded, with fresh material added and the crown restored so they drive smooth again. Behind that is 13 years of hauling and placing aggregate across this valley, which is how we know which stone and build hold up in local ground and weather.


Running our own trucks and equipment keeps the work quick and the pricing honest, with no rental or subcontractor markups stacked onto your total. You deal directly with the owner on every job, so you always know exactly what went into the ground beneath you. We build the very same way for landowners in Hamilton, Stevensville, Florence, and Missoula. When your surface needs fresh gravel or a full rebuild, reach out on our contact page and we will get it solid again.

Our Gravel Services 

  • Gravel Driveway Installation

    A new gravel drive is built in layers. We excavate and grade the route, lay and compact base rock, then finish with angular surface stone that interlocks. The result is a firm, well draining driveway that handles daily traffic and holds its shape.

  • Driveway Regraveling and Top Dressing

    Gravel thins and scatters with steady use. We regravel worn drives by adding fresh material, then grade and compact it back to a smooth, crowned surface. Top dressing restores depth and drainage without a full rebuild, returning a tired driveway to drivable condition.

  • Base Rock and Subbase Placement

    Everything above depends on what lies beneath. We place and compact base rock and subbase to carry the load and stop surface gravel from sinking into soft soil. This structural foundation keeps a driveway from rutting, shifting, or failing under heavy, real weight.

  • Crushed Stone Supply and Delivery

    Choosing the right stone matters as much as placing it. We supply and deliver crushed rock, base material, and surface gravel suited to each layer and use. Angular crushed stone locks together better than round rock, giving you a surface that stays put.

  • Gravel Grading and Compaction

    Loose gravel is only ever half the job. We grade material to the proper crown and thickness, then compact each layer so it binds into a stable surface. Compaction separates a driveway that lasts from one that ruts and washboards within a season.

  • Parking Area and Pad Graveling

    Vehicles, equipment, and buildings all need firm ground to sit on. We gravel parking areas, equipment pads, and building sites, grading and compacting them to shed water and bear weight. A built pad keeps trucks and structures out of the mud year round.

Benefits of Gravel Driveways

A Stable Driving Surface

Properly layered and compacted gravel gives you ground you can count on. Tires grip, loads stay supported, and the surface does not shift under daily use. Instead of soft ruts and loose stone, you get a firm, stable drive that feels solid underfoot.

Excellent Drainage

Water is where gravel shines. Built with a crown and the right stone, your surface lets rain and snowmelt drain through and run off rather than pooling. That drainage keeps the driveway firm and prevents the muddy, sinking spots that plague weak drives.

Less Dust and Mud

A well built gravel surface strikes the right balance. Compacted base and angular stone cut down the mud after storms and the dust in dry spells. You track less mess into vehicles and buildings, and the drive stays presentable through changing seasonal weather.

Lower Upkeep Over Time

When a gravel surface is done right from the base up, it demands far less attention. Good drainage and compaction mean fewer potholes, less washing away, and longer gaps between touch ups. You spend your time using the drive rather than repairing it.

Fast, Efficient Installation

Gravel work moves quickly compared to paved surfaces. With our own trucks and equipment, we haul, place, grade, and compact in a tight window, so your drive or pad is usable soon. You get a finished surface without a drawn out, disruptive project.

A Clean, Finished Look

Freshly graded gravel simply looks cared for. coverage, a defined edge, and a proper crown give your property a tidy, intentional appearance. Beyond pure function, a clean drive lifts the whole look of your home, ranch, or business at first glance for visitors.

Frequently Asked Questions

  • How deep should gravel be for a driveway?

    Most drives need four to six inches of surface gravel over a compacted base, with the full build often reaching twelve inches or more. With 13 years of experience, Bohlander Construction sizes each layer for properties in Corvallis, Montana around traffic and soil.

  • What is the best gravel for a driveway?

    A layered mix works best: larger crushed rock for the base, medium stone in the middle, and smaller angular gravel on top. Angular stone interlocks and drains well, while round river rock shifts underfoot. The right combination gives you a stable, lasting surface.

  • How often should a gravel driveway be regraveled?

    It depends on traffic, weather, and how the base was built, but many drives benefit from fresh surface material every few years as gravel thins. Bohlander Construction regravels and regrades worn driveways around Corvallis, Montana so they drive smooth and shed water once.

  • Does a gravel driveway need to be compacted?

    Yes, and skipping it is a common mistake. Uncompacted gravel stays loose, ruts quickly, and mixes into the soil below. Compacting each layer binds the stone into a firm surface that carries weight and resists washboarding, which is exactly why we compact throughout.

  • Why does angular gravel work better than round rock?

    Angular stone has sharp, irregular faces that lock together under pressure, forming a tight, stable surface. Round river rock rolls and scatters instead, leaving loose, shifting patches. For a driveway meant to bear traffic and hold its shape, angular crushed stone is best.

  • Do I need a base layer under my gravel?

    Almost always. Surface gravel laid straight on soil sinks in, ruts, and disappears fast. A compacted base of larger rock spreads the load and keeps the top layer where it belongs. That base makes the difference between a lasting drive and a mess.

  • How do I keep my gravel from washing away?

    Washout comes down to water and stone choice. A proper crown sheds runoff to the sides, angular gravel resists moving, and ditches carry water away. On steeper drives, we may add a stabilizing grid so the surface stays in place through heavy rain.

  • How much gravel will my driveway need?

    Length, width, and depth decide the total. Multiplying those dimensions and dividing by twenty seven gives the cubic yards required for each layer. We calculate the amounts for you, so the right volume of base and surface material arrives without shortfalls or excess.
