how to repair crumbled concrete patio....?
a couple years ago we posted a question concerning our patio the had an area where about a 6' x 6' area of the concrete had crumbled/broken up ,,, due to temp. or moisture when it was poured?
Some one gave a procedure that we followed & the area to this day has held up fine. Now we can't remember the procedure?!! First we cleaned it up as much as possible of the loose rubble & then we remember we poured muriatic acid on the area... but after that we don't recall the next steps we used & the final mix of concrete poured on the area. Would anyone heard of this or have any idea how this procedure worked? Neighbor has the similar concrete problem & would like to tell them what we did!
Thanks for any ideas!
