Let the gravel driveway dry, rake displaced rock back from the edges, fill ruts and potholes with packed road base, and clear the ditch or culvert before the next storm. A true washout needs road base compacted in first, not loose stone dumped on top.
HARDROCK Sand and Gravel, a supplier in Sherman, TX since 2016, delivers the road base, crushed rock and rip rap these repairs use. This guide covers what heavy rain does to a gravel drive in Grayson County, how to repair it in order, and how much rock a patch takes.

Heavy rain moves water across and under a gravel drive, and the water takes rock and soil with it. The common damage is ruts where tires pressed into wet ground, potholes where soft clay worked up through thin rock, edges that slumped, and washouts where runoff cut a channel.
Grayson County makes this more likely on many lots. The county's own history page calls blackland prairie a dominant feature of much of the county, and clay like that goes soft when it soaks up water. The Handbook of Texas puts average rainfall near 37 inches a year, and wet years run higher: the Texas Almanac lists 43.6 inches for 2019. In the north, the Handbook describes loamy or sandy surface soils draining toward Lake Texoma and the Red River, where loose ground moves with runoff.
The rock also gets pushed into the mud. Our gravel driveway page explains why a drive with no firm base keeps losing rock into soft ground, and why the repair below starts with the base.
How do you repair ruts and potholes in order?
Work in this order: wait for the surface to firm up, rake displaced rock back, cut out any soft spot, fill it with road base packed in thin layers, then top with crushed 57 rock. Skipping the base and topping up loose stone is the repair that fails again.
- Wait for firm ground. Working soaked gravel and clay together smears them into mud. Start once a boot no longer sinks.
- Rake the edges back. Pull rock that was pushed to the sides or down the lane back toward the middle, and set aside what is clean.
- Dig out the soft spot. Remove mud and loose fines from a pothole or rut down to firm ground, so you build on something solid.
- Fill with road base. Add it in thin layers, wet and compact each one. This is the layer that carries weight.
- Top with 57 rock. The crushed angular stone locks together, drains and gives tires grip. Rake it level with a slight crown so water runs off.
How do you stop the next storm from washing the drive out again?
Give water somewhere to go. Keep a slight crown on the driveway so rain sheds to the sides, keep the ditch and culvert clear, and cover the culvert outlet and any cut bank with rip rap over filter fabric. Rock that heavy stays put where small gravel would travel downstream.
The outlet is where many drives fail. Water leaving a culvert at speed digs a hole and undermines the road above it. Rip rap set over fabric at that spot takes the energy out of the flow. HARDROCK sets rip rap on its own jobs the same way: the bank is cleared, fabric is rolled down the slope, rock is fed to the bank and the stones are hand-set so they lock together.
Drives near the river and lake in northern Grayson County deal with more moving water; the Denison page covers bank and drainage work there.
How much rock does a repair need?
A repair needs rock in proportion to the damage: multiply the length, width and depth of the damaged area in feet and divide by 27. A 4 by 10 foot rut filled 4 inches deep is 13.3 cubic feet, about half a cubic yard of rock. Add 5 to 10 percent for settling.
Whole-drive numbers are in the driveway quantity guide, with worked examples from a house drive to a 200 foot lane. For patching, a half yard here and a yard there add up quickly, so list every bad stretch before you call.
When should you call a supplier instead of patching?
Call when damage runs over a long stretch, the same spot washes out after every storm, a culvert is undermined, or the base underneath has failed. At that point the repair is a rebuild: shaped subgrade, compacted road base and fresh top rock, sized in cubic yards.
HARDROCK Sand and Gravel delivers the material or builds the drive; see delivery for how an order works. Tell HARDROCK the address, the length of the damaged stretch and where the water goes, and the load is priced by phone. Call 903-420-0330 Monday to Thursday from 6:00 AM, Friday from 9:00 AM or Saturday from 9:00 AM to 2:00 PM.
What else do people ask about repairing a rain-damaged drive?
Three questions follow the repair steps for a rain-damaged driveway: how long to wait before regrading, which gravel to avoid for the repair, and who can deliver the road base and rock.
How long should I wait before regrading a wet gravel driveway?
Wait until the surface is firm enough that a boot no longer sinks and the rock stops rolling under a vehicle. Working soaked gravel and clay together smears the two into mud, so patience saves material. How long that takes depends on the soil and the weather.
Can I fix a washed-out driveway with pea gravel?
Pea gravel is a poor repair for a drive. The stones are rounded, so they shift under tires instead of locking together. Packed road base fills the washout, and crushed 57 rock goes on top; both are on HARDROCK's product list.
Can HARDROCK deliver rock to repair a washout?
Yes. HARDROCK Sand and Gravel delivers road base, 57 and 67 rock and rip rap in Sherman, Denison and Grayson County, and also builds gravel driveways. Call 903-420-0330 with the address and the size of the damage and the load is priced by phone.
What should you read after this guide?
The other HARDROCK guide covers how much gravel a driveway needs: the cubic-yard formula, three worked examples and the layers a Grayson County clay lot calls for before you place an order.
