After the excavation is complete, the site is often covered, either by replacing the soil removed earlier (backfilling), or by new developments.

Excavations "incidental" to construction are exempted from the excavation tax, provided that not more than 1,000 cubic yards of "earth" are removed from the construction site during any given tax year.

Keyhole excavation was carried out extensively in Roman military archaeology by Ian Richmond, who produced overall plans of many forts and fortresses in northern Britain by the judicious excavation of small narrow trenches, carefully placed to check critical details of the fairly predictable layout of their internal structures.
The normal excavation method is to empty a pit in such a way that its section may be recorded, ideally on more than one axis, in order to study the way in which it was filled and to recover artefacts and environmental samples that will help elucidate its function as well as providing dating evidence.
