Thin plastic like this is often called a vapor retarder—meaning it slows the vapor down but doesn''t stop it. A much better approach is a true vapor barrier, with characteristics that conform to the requirements of ASTM E1745, "Standard Specification for Water Vapor Retarders Used in Contact with Soil or Granular Fill under Concrete Slabs."
May 21, 2018· Do not allow children to use it without adult supervision, as it is toxic in nature.

cement faces its toughest challenge under ground—in oil and gas wells where envi ronmental conditions are far more severe than any encountered on the earth''s surface. This artic e outlines the chemistry of port land cement, the variety used to cement casings in wells and provide zona isolation, and explains how additives faci itate cement
Generally speaking, oilfield cement is thinner and exhibits far less strength than cement or concrete used for construction due to the requirement that it be highly pumpable in relatively narrow annulus over long distances. Various additives are used to control density, setting time, strength and flow properties.
John, you can use a concrete mix to repair this area because it is over 2" in thickness. Use a bonding agent and pin it like you were describing with the rebar. Frame it in and pour the material. Remove the frame work after 24 hours. You can use either Pam or WD 40 on the framework as a release agent.
