Josh Jameson: I think the concrete was cast slightly under the window, so the window frame would prevent it from flipping out.
JC Mac: nicely done!
B Miller: I used a somewhat similar method to repair a cracked concrete sill. \n\nI actually gently opened it a bit wider (the split was running the long way and but for the embedded rebar, I could have cracked it completely off — about 2" of a strip!). I moistened the existing concrete inside the crack with a spray bottle of water, and fastened a 2×4 along its front edge by using concrete bolts to hold it past each end of the sill into the concrete block of the wall. That provides a means to force the cracked "outer" section of the sill TOWARDS the window, or, directly back in towards its other half. Now I just used some very moist concrete mix to fill in the crack, after it was filled, I then tightened the screws to draw up the 2×4 and compress the halves together tightly, which squeezed out some of the concrete I had filled in. Then I just troweled it off and dress the surface nicely, trying to feather the concrete out over the existing concrete to make the repair as seamless as possible. Whala, a day later (plastic over it to slow drying, and occasional moistening to help it cure strong), and I was able to prime and then paint the repaired sill and you can't tell anything had been amiss…
Who dis?: That's quite clever. i might have have sloshed some sbr down there first and used some in the mix.
