The magnitude of consolidation can be predicted by many different methods.

If the stress is reapplied, the soil will consolidate again along a recompression curve, defined by the recompression index.

The soil which had its load removed is considered to be overconsolidated.

A soil is called overconsolidated if the current effective stress acting on the soil is less than the historical maximum.

The preconsolidation pressure can help determine the largest overburden pressure that can be exerted on a soil without irrecoverable volume change.

Preconsolidation pressure cannot be measured directly, but can be estimated using a number of different strategies.
