Phillips Hardy came to the rescue by using Helix Steel’s Micro Rebar

Rebar redevelopment

US construction company Phillips Hardy was called in to help a customer dealing with aging bridge infrastructure, resulting in increasing construction demands and funding shortfalls. Phillips Hardy sought ways to make the infrastructure more resilient, enabling longer lifespans and lower lifecycle costs, while supporting higher traffic demands. That search led them to Helix Steel and a twisted steel micro-reinforcement technology called Micro Rebar. “By adding Helix Micro Rebar to the concrete mix, we have been able to deliver a bridge deck overlay that is less susceptible to deterioration and cracking,” said Jason Stastny, project manager from Phillips Hardy.

Helix Steel is the manufacturer of twisted steel micro rebar (TSMR), a three- dimensional concrete reinforcement technology that increases shear strength, durability and ductility while providing pre-crack capabilities. Said to be four times the tensile strength of rebar and one-third of the weight, TSMR enables a reduction in overall carbon footprint and provides valuable LEED credits. Since 2003, TSMR has been used in applications ranging from structural foundations, walls and slabs to suspended structural concrete, paving and tunnels.
