Before you start
Stop and record the last correct reference point. Support loose loops or damaged ground before removing anything, and reproduce the fault on a spare sample if possible.
Try this example
Stop at the first round that no longer lies flat. Compare its six sectors with the last flat round; undo that round and change only the identified cause.
Check your result
- Compare the repaired area with an undamaged neighbor after relaxing or finishing the sample. Recount the boundary before continuing beyond the repair.
- A repair may remain visible. If the foundation is weak, reinforcing or replacing a section can be more reliable than hiding the surface fault.
