Stop covering the work until the installed base can be compared with the agreed system

If a paver base appears inadequate, preserve the condition before bedding and pavers hide it. Compare the installed depth, material, subgrade preparation, compaction, drainage, and edge conditions with the contract, drawings, manufacturer requirements, and actual site conditions. The remedy should follow evidence, not only a surface photograph or a disagreement about a single depth number.

Document what exists before asking for a correction

Take dated photographs and measurements at representative locations. Keep delivery tickets, material descriptions, compaction information if available, and the original proposal or cross-section. Note whether the base is already exposed, partially covered, wet, disturbed, or carrying traffic.

Ask the contractor for a written technical response

The contractor should explain whether the installed section matches the agreed scope and, if not, how it proposes to correct it. Request the repair limits, material and compaction method, cost responsibility, and schedule effect in writing. This creates a clear project record before positions harden into a dispute.

Separate inadequate thickness from inadequate support

A base problem can involve more than depth. Soft subgrade, poor drainage, unsuitable aggregate, weak edge restraint, or poor lift compaction can produce failure even when the total measured thickness looks acceptable. Conversely, a thinner section is not automatically defective if the approved design and site conditions support it.

Use an independent evaluator when the documents do not resolve the disagreement

A qualified independent professional can compare the specified and installed system and identify what evidence is still missing. The purpose is to establish the performance issue and repair path, not simply to produce a second opinion that repeats one party’s preference.

Agree on an observable acceptance point before rebuilding

Define what will be checked before bedding and pavers proceed, such as subgrade condition, compacted depth, elevations, drainage, and edge restraint. If the issue becomes contractual or legal, preserve communications and use qualified California advice rather than making payment decisions without understanding the agreement.
