Excavation depth
Existing surfaces, soft areas, finished threshold levels and the chosen build-up determine how much material must be removed.
Driveways
Driveway groundworks
Driveway groundworks establish the depth, strength, levels and drainage that the visible finish depends upon.
Photos, drawings or a short description can help explain the current condition.

Start below the finished surface
A shallow dig and a thin stone layer can look acceptable at handover but fail under repeated vehicle movement. Formation and compaction should reflect actual loading and ground condition.
Ground, access and water
Compaction
Sub-base is normally built and compacted in controlled layers rather than tipped once and rolled at the surface.
Service covers
Manholes, stop taps and other access points should finish neatly and remain accessible within the new levels.
What to mention
What Flyson needs to understand about the ground
- Describe what is already known about excavation depth.
- Explain the priority or constraint around compaction.
- Include enough context to discuss service covers without assuming a product or method before the property is understood.
Questions specific to driveway groundworks
Why is ground preparation expensive?
Excavation, haulage, disposal, imported aggregate, plant and compaction are substantial parts of a durable driveway, even though they disappear at completion.
Can rubble be used as sub-base?
Uncontrolled mixed rubble is not the same as a specified, well-graded sub-base material. Suitability and compaction matter.
How are soft spots handled?
They should be excavated or treated appropriately rather than covered, with the changed scope recorded if conditions differ from the assumptions.

Driveway drainage
Driveway drainage coordinates surface falls, channels, permeable areas and a suitable destination before the final surface is installed.

Block paving offers pattern, colour and repair flexibility, but relies on a well-compacted base, restrained edges, controlled falls and correct jointing.
