Walls; Fireplace Surrounds, Partition and Structural Walls, Concrete Bottle Nook beneath kitchen countertop: We wanted to recreate a wall that had fissures, cracks and veins that would resemble the cliffs that the house was constructed on. It should be noted that we were not so concerned with exactly replicating the surrounds, but only to give the feel/impression of the surrounds. The technique used to pour the walls was to randomly pour the concrete in the formed walls and lightly vibrate them as we wanted to keep some random air pockets to produce a bug holed rock look (too much vibration would limit the fissure effect). Once we made a first pass with the concrete in the wall…sometimes pouring a third at a time (or even two-thirds at a time depending where we wanted the fissure/fissures) we would stop and move the concrete pump to a different location and then we placed stones, shells etc onto the top of the irregular tops of the wall. In 30-45 minutes, after the initially poured concrete in the wall took a slight set, we would pour concrete again over the first pour which we dropped/placed rocks and shells on the top of the partially set up wall.
