Grinding processes the agreed part of the stump; extraction removes the root ball. Compare waste removal, backfilling and the condition of the area afterwards too.
Two methods, different effects on the ground
| What to compare | Grinding | Extraction |
|---|---|---|
| What is removed | Wood within the agreed depth and width. | The root ball is lifted out of the ground. |
| What is left on site | Shredded wood mixed with soil. | A hole and the extracted material. |
| What to consider | Buttress roots, depth, remaining material and backfilling. | Working space, underground services, the hole and moving the root ball. |
| Roots further away | May remain in the ground. | Removing the root ball does not mean removing every root. |
The name of the method alone does not tell you whether the ground will be ready for your plans. Agree the exact scope.
When to consider grinding
Grinding may suit an established garden or a site where you want to limit excavation. Specify the depth and width to suit future use. The buried stump and buttress roots are often wider than the visible cut through the trunk.
GREON distinguishes standard grinding to 15 cm from deeper work down to 45 cm by agreement. The maximum depth is not automatically included in every job. See our stump-grinding servicefor current details; confirm waste removal, backfilling and final levelling separately.
When extracting the root ball may be preferable
Stump and root-ball extraction may suit major ground remodelling or a project where the root ball must be physically removed. There must be enough space to operate machinery and handle the material safely.
Underground services, fences and buildings may restrict the options. Before construction, the design and ground requirements determine the method. A stump no longer being visible does not confirm that the site is ready for a structure.
Allow for the work afterwards
- Which parts of the stump and roots will be removed.
- What will remain and what will be taken away.
- Who will supply backfill and finish the surface.
- Whether transport is included and how VAT is shown.
- The condition needed for subsequent planting, a lawn or construction.
Remaining wood gradually decomposes, and the area may need topping up with soil later. Fresh woody debris is not automatically suitable for direct grass seeding.
What to send us for a recommendation
Photograph the stump with a tape measure at ground level, its surroundings and the narrowest access point. Include the town or village, number of stumps and intended use. Mention slopes, stones, underground services and nearby buildings.
This information helps establish the scope or whether a visit is needed. See our guide to measuring and photographing a stump. Explore our stump and root-removal service.
Frequently asked questions
Does grinding remove all the roots?
No. It processes the agreed part of the stump and, where specified, buttress roots. More distant or deeper roots can remain.
Is grinding to 45 cm always included?
No. This is a maximum depth, subject to agreement and site conditions. GREON distinguishes standard work to 15 cm from deeper grinding.
Which method is better before construction?
The method and scope should match the design and ground assessment. Grinding or extraction alone does not confirm that the site is suitable for foundations.
