What technique should be used when backfilling with a TLB?

Using a layering technique when backfilling with a Tractor-Loader-Backhoe (TLB) is essential for several reasons. This approach involves adding material in successive layers, which allows for better compaction and stabilization of the fill material. By distributing the load evenly, it reduces the risk of settling or shifting, which can lead to structural issues in the long term.

Compacting the material in layers also helps to eliminate air pockets and voids, providing a more solid and stable foundation. If larger amounts of material are dumped all at once or if uncontrolled filling is practiced, it could result in uneven settling and could lead to weaknesses in the structure or surface above.

Overall, the layering technique ensures that the material is properly compacted and stable, essential for the integrity of any construction or landscaping project.
