Fiber Crib Blocks
Fiber Crib Blocks are designed to provide high-capacity, permanent roof support. Steel-fiber reinforcement provides a higher load capacity and toughness as compared to concrete blocks alone.
Open Stack Fiber Crib Blocks Concrete Roof Support
High-Strength & Dimensionally Stable
Concrete supports are resistant to atmospheric deterioration and provide “cut-able” capabilities, ideal for “mine through” applications.ust.
Closed Stack Fiber Crib Blocks Concrete Roof Support
- Permanent standing support at shaft or slope bottoms
- Permanent support along roadways & in air courses
- Support under beams or cross-bars
- Support for mine through areas in longwall panels
- Cut-able support at rib-line in head or tail gate entry
