New architectural design techniques have given tilt-up concrete panels a new look. Traditionally selected for economy, tilt-up construction is now being chosen for beauty as well. The new techniques include sculptured panels, dimpled surfaces, wide borders that make panels appear smaller, and panel connections with inconspicuous joints or narrow, painted recesses instead of bulky columns. Other improvements provide a wide variety of surface treatments. Exposed aggregate and rock-faced panels are being used to produce dramatically attractive buildings at low cost. White cement facing or white cement concrete panels provide permanent beauty without expensive upkeep. Broomed, ribbed and pattern-stamped surfaces, as well as various geometric patterns, can be cast with relative ease into horizontal slabs which are raised into position to become walls of architectural concrete. The advantages of tilt-up walls are by no means limited to beauty and economy. For minimum maintenance the surfaces can be left unpainted; color can be incorporated in the concrete. The panels resist moisture, weathering, rot, and rust.
