The Technology Behind
GPS-Precision Grading
and LiDAR-Verified Results
Two technologies. One goal: a driveway that drains correctly, stays smooth, and is verified with data.

How It Works
Most gravel driveway repairs fail within a year because the grade was set by eye. GPS-precision grading eliminates that problem entirely.
A GPS-guided grader blade sets the exact crown and slope across your entire driveway. The operator locks in the target cross-slope — 3% is the engineering standard for proper drainage — and the blade maintains that slope automatically, even as the machine moves across uneven terrain. Real-time slope feedback on the in-cab display means the operator knows the grade is right before the blade ever leaves the ground.
Eliminates Guesswork
The blade holds the target slope automatically, even across uneven terrain. No eyeballing, no raking by hand, no hoping it drains.
Repeatable Results
Every pass follows the same GPS reference. Whether it is the first driveway or the fiftieth, the grade is identical.
Proper Drainage Every Time
A 3% crown is the engineering standard for gravel driveway drainage. GPS grading hits that target within inches across the full length.
Works on Hills and Slopes
A tilt-mount blade adjusts automatically on sloped driveways, maintaining the correct cross-slope even when the machine is on a grade.
Grade. Verify. Guarantee.
GPS sets the grade. LiDAR proves it was done right. A written guarantee backs both. That is why our results last — and why we can put it in writing.

Laser Precision.
Millimeter Accuracy.
LiDAR (Light Detection and Ranging) uses laser pulses to measure distances with millimeter precision. The same technology powers:
We've adapted this technology specifically for gravel driveway drainage diagnostics — and paired it with gimbal stabilization for results accurate to \u00B10.3 inches.
