TP-Joint is a premolded, reusable, temporary joint filler for protecting saw cut crack joints from damage and contamination during the construction process. For tilt-up concrete construction, the filler is suitable for masking saw cut slab joints in areas where panel concrete will be placed. Accommodating up to 3/8-inch joint widths, it eliminates costly grinding of reflective concrete fin on tilt wall panels. The available applicator installs more than 1000 feet of filler per hour.
