Erosion Control & Slope Stabilization in Paradise Valley, Montana

Between snowmelt, gully-washers, and the grades this valley is built on, moving water is constantly trying to take your ground somewhere else. EZ Road Repair stops erosion at the source across Emigrant, Livingston, Pray, Gardiner, and the rest of Paradise Valley — rerouting the water, reshaping the damage, and armoring the places where flow concentrates, so slopes, banks, and cuts stop shrinking every spring.

When erosion control matters

  • Gullies cutting deeper across a slope, pasture, or bank each runoff season
  • A streambank, pond edge, or ditch bank losing ground to moving water
  • Washouts below culvert outlets, road edges, and driveway discharges
  • A cut or fill slope from past construction that never stabilized
  • Bare ground around a new build that needs to hold until vegetation takes over

Common problems we solve

  • Concentrated discharge cutting gullies — we fix the source (culvert outlets, ditch grades), reshape the channel, and armor it with riprap sized to the flow.
  • Slumping, rilling slopes — regraded to stable angles, drained with swales that spread water, and topsoiled for revegetation.
  • Banks under attack — riprap armor bedded on prepared, fabric-lined surfaces where water works hardest.
  • Erosion that keeps undermining a road — the road-edge and slope fixed together; see road repair and spring runoff damage repair.

Our approach

We read the water before we touch the dirt: where it gathers, where it accelerates, and where it lets go of the soil it’s carrying. Then we fix in that order — reroute and slow the water, reshape the damaged ground, armor the concentrated paths, and prep the rest to grow. It’s the same drainage-first discipline behind our drainage systems and land reclamation work, aimed at making the repair the last one.

Good to know

Frequently Asked Questions

Why does the same slope or bank erode a little more every year?

Because erosion is self-reinforcing: every rill concentrates the next storm's water into a deeper channel. Until the water is rerouted and the surface is armored or stabilized, each spring picks up where the last one left off. Fixing the water is the cure; reshaping alone just resets the clock.

What is riprap and when is it the right fix?

Heavy, angular rock placed on a prepared surface to armor ground against moving water — banks, culvert outlets, spillways, steep ditch sections. It's the right fix where flow is concentrated and fast. Sized right and bedded on fabric, it stays put; undersized, it just relocates downstream, which is why we size it to your actual flows.

Can you fix a hillside that's washing out below a road or driveway?

Yes — that's classic Paradise Valley damage: road runoff concentrates at one point and cuts a gully down the slope. We fix the discharge (culvert outlet, ditch grade), reshape the gully, armor the flow path, and set the slope up to revegetate so it holds without us coming back.

Does erosion control always mean rock, or can it look natural?

Plenty of it is shaping and vegetation: regrading to spread water instead of channeling it, building swales that slow it down, and prepping slopes with topsoil so grass takes over the stabilizing job. Rock goes where water concentrates; the rest can look like it was never touched.

When should erosion work be done?

Late summer and fall — the damage from spring is visible, the ground is workable, and the fix is in place before the next melt tests it. Call (406) 623-9075 before the freeze and you're ahead of the season.
