Profile: Redifix Ltd. is a supplier of wall tie equipment. Our product line includes Cracktie®, Macktie®, Fastie®, Lintie®, and Resimac®. Our Fastie® provides a fixing to brick and stone masonry, with low stresses transmitted to the base material by PVC expander during setting of the tie. The Fastie® is used in materials with a compressive strength of only 5N/mm2. This versatile remedial wall tie works well in concrete and dense strong block work. The Fastiereg; is manufactured from A2, 300 series, austenitic stainless steel with PVC expansion elements to both inner and outer leaves of the cavity wall. The tie is supplied and can be installed fully assembled for quick & easy application. Our Mactie® features a unique expansion system which results in low radial stresses on the wall base material, whether brick, block or concrete. This unique design replaces traditional cone expansion of general fixings with a hexagon nut, preventing turning, and inducing a barrel or convex shape expansion and reducing point loading.
