Surface Segregation — Laser Level Diagnosis
Define the finished purpose, reference levels, underlying material condition and the evidence required by the receiving operation. Geometry alone does not establish structural or agronomic performance.
This reference assembles relevant extracts from the guide library. It is general project planning, not a local project report, verified specification or translated technical publication.
How to Level a Paddock
To level a paddock, first decide whether the job is local smoothing, drainage correction or a broader designed landform. That decision determines survey coverage and material movement.
Before moving material
Record the cropping plan, productive-layer depth and water observations.
Receiving operation and checks
Recheck the profile and complete the intended seedbed preparation. Observe drainage after correction and inspect retained topsoil depth.
Do not flatten natural terrain without a defined agricultural purpose.

Repeated settlement suggests the problem may lie below the visible surface. Filling a depression again can hide a weak or poorly prepared layer.
Before moving material
Record the timing and extent of movement and review material history.
Receiving operation and checks
Repair the confirmed cause and re-establish the intended layers. Monitor the repaired area under the intended use.
A scraper guide cannot diagnose geotechnical failure from a photograph.

Water that returns to a repaired depression may indicate an unchanged outlet control, continuing inflow or settlement. Treat the recurrence as new evidence rather than simply repeat the same pass.
Before moving material
Compare the repaired levels with the drainage route and water observations.
Receiving operation and checks
Observe another suitable rainfall or irrigation event. Record where and when water reappears.
Subsurface and hydraulic causes may need specialist assessment.
