How Helix® Micro Rebar™ Makes Underground Projects Better
Helix® Micro Rebar™ has been used in shotcrete, underground paving operations, and tunnel linings for over a decade. It greatly simplifies and speeds up the placement of underground concrete by eliminating the need to transport rebar from the surface. Meeting or exceeding all industry standards for shotcrete and tunneling, Helix® Micro Rebar™ makes shotcrete and precast tunnel linings easier to place/fabricate. We are proud to manufacture in Michigan with American workers, and look forward to servicing your federally funded projects with Buy America products rather than products imported from foreign sources.
