DIY repair – Poured concrete cracks

I frequently see poured concrete cracks appearing in the foundation walls of homes I am inspecting.  The majority of these are typical shrinkage cracks or in older properties small settlement cracks and not considered structural.  That said, they ought to be repaired to prevent water intrusion or further deterioration.

poured concrete cracksI am typically queried by my clients as to how to deal with them, but as part of the Standards of Practice, I am not required to tell people how to repair items themselves.

I personally feel, however, that if I am certain the crack is not structural and does not need to be referred to a structural engineer, then why should I refer them to a Basement Crack specialist who will charge thousands of dollars? Assuming my clients are half competent, they could at least try to fix poured concrete cracks themselves for a fraction of that cost.

I have in the past told my clients about these crack “Specialists” only to find later that the cracks have been “filled” with urethane foam.  Expanding foam will stop water intrusion but will deteriorate over time.

An epoxy repair provides both a moisture barrier and a structural improvement to the crack. Many products exist in the market, but I found this particular video to be especially helpful for cracks that can be repaired using low-viscosity epoxy repair.
