    sandy soil drained the Fast-Setting Concrete Mix
    The sandy soil apparently drained the water, cement and fine aggregate and resulted in post holes half filled with Quikrete Fast-Setting Concrete Mix (after adding water).

        This product was easy to work with with no fuss or must of mixing on the side just pour it in the hole and add water. Sets up quickly so you can continue to work on your project without losing a day. I would recommend this to anyone looking to put in post holes.

        Quickset concrete mix
        The yard has a bit of an incline, so I had to stack a row to get the proper level height. The concrete needs to be sifted to get pebbles,etc out. The key is to lightly mist the mix to begin the hardening process.. definitely would use again
