Tunnel Linings

Helix is proven in shotcrete, cast-in-place tunnel linings and has been fully evaluated to exceed industry standards in full-scale precast tunnel segments. Helix is fully Buy America Compliant, eliminating the need to seek waivers to purchase foreign materials with American taxpayer money. In tunnel linings, Helix’s performance exceeds that of imported hook-ended fibers, which have become the industry standard. If you’re ready for better performance and to put American workers’ dollars toward American products, we welcome your business.
