Specifically designed helical ties to connect masonry into structural timbers, used to re-connect bowing walls back into floor structures and structural studwork. Bowties provide an effective, inexpensive, aesthetically sympathetic alternative to traditional tie bars and patress plate lateral restraints. Lateral restraint ties can be used in conjunction with the (Helibeaming) helical beaming system to provide lateral restraint across stairwells etc. Thor approved schemes are available with a 10 year insurance backed structural warranty.
