DN-34: Formliners Handout

Pdf Summary

Formliners are used in architectural precast concrete to create surface textures, patterns, and shapes that contribute to the overall aesthetic of a building. They can be incorporated into or attached to the surface of a mold, allowing for a wide array of design possibilities. Formliners can mimic traditional building patterns such as masonry, wood board markings, and stone textures, as well as create custom graphics including highly detailed three-dimensional designs. New techniques and technologies, such as CNC milling, have made it easier to produce custom work at a reasonable cost.<br /><br />When using formliners, it is important to select the texture and type best suited to the project. Factors such as the size of the wall and the distance from which it will be viewed should be taken into consideration. Other factors that impact the cost of a formliner include the material used, detail of the design, changes made after the original design, size, and the number of reuses obtained.<br /><br />Formliners can also be used for lettering on precast concrete surfaces. The profile or cross section of the letters should be carefully considered to ensure clear and regular shadows. Recessed letters with right angle shoulders and a flat back stand out clearly, while letters with square shoulders may appear irregular due to the broken surface of the back.<br /><br />In addition to formliners, there are other techniques such as photo-engraving and photographic concrete that allow for even more design flexibility. Photo-engraved liners create surface patterns based on scanned images or photographs, while photographic concrete allows designers to visualize unique designs on concrete surfaces. These techniques can be used to create different effects depending on the angle of light and the viewing distance.<br /><br />Overall, formliners offer architects the opportunity to create visually interesting and unique precast concrete facades that contribute to the overall impression of a building.
