THERMOFORM Concrete formliners are rigid plastic liners that are used to achieve detailed patterns and textured concrete surfaces for precast architectural concrete. You may select from a variety of patterns, or custom order to fit your needs – at only a nominal additional cost. All patterns are available in three different ranges: Single Use, Medium Reuse and High Reuse.The Single Use, made from styrene, is ideal where the formliner will be used only once. The Medium Reuse, made from ABS materials, can be used up to 10 times. The High Reuse can be used up to 20 times under most conditions. The vacuum-forming technology used in this product line allows virtually unlimited texturing opportunities, offering the most flexibility in custom designed patterns. This low cost reproduction process allows you to add exceptional economic options to the design integrity of your precast concrete projects. Due to the stretching of the plastic sheet material that occurs during the reshaping of the thermoforming process, some patterns with a high degree of texture or relief should not be produced in the thinner, single-use material. Normally supplied in 4' x 10' sheets.
