  • Field controls for foundation drainage in a Canadian residential renovation

    Foundation drainage can turn a controlled residential renovation into a schedule delay, a budget dispute, or a warranty issue. This guide explains what usually goes wrong and how to control it before work starts.

    What usually goes wrong

    The failure usually starts when foundation drainage is treated as a small detail instead of a project control item. Teams rely on assumptions, incomplete drawings, verbal decisions, or unclear responsibility between owner, designer, supplier, and contractor.

    Why it becomes expensive

    In a residential renovation, the cost impact grows when the issue is discovered after procurement, rough-in, inspection, or handover. At that point the fix can affect schedule, access, finished work, warranty, and client trust.

    How to prevent it

    The best prevention is a written control: define the requirement, assign the owner, attach proof, review before release, and confirm completion before the next trade covers the work.

    Prevention checklist

    • Confirm responsibility before work starts.
    • Attach drawings, photos, product data, and approvals to the project record.
    • Review cost and schedule impact before accepting changes.
    • Require inspection evidence before covering or closing the work.
    • Store closeout proof for warranty and dispute protection.
