Drain tile Inspection

What You Should Know:

Drain tile must be installed in clay soil types. The building inspector determines soil type at the footing inspection. You must review the footing inspection to see if a complete drain tile system is called for.   If it is, then your excavator must be informed so that they can request a drain tile inspection.  This inspection is a separate inspection to view the rock.    If you choose to install drain tile as precaution but is not indicated as necessary by the building inspector, an inspection is not needed (and you will be charged for the extra inspection if you request one that is not needed.)   However, if the building inspector calls for drain tile, it MUST be installed and inspected.
