🧱 Reinforce your concrete like a pro — stronger, smarter, unbreakable.
Basalt Chopped Fibers are ultra-fine (17 micron) 12 mm strands designed to integrate seamlessly into concrete and polymer mixes, significantly enhancing tensile, compressive, and flexural strength by up to 44%. Resistant to extreme temperatures (-452°F to 1200°F), chemical attacks, and water absorption, these fibers improve crack resistance and durability, making them ideal for high-performance concrete applications including countertops, bridges, and shoreline structures.

Seems to be helping reduce hairline cracks in ferro-cement
I got this as an additive for making non-ferrous ferrocement. I am still just experimenting at this point, but this does seem to help reduce cracking. It is very challenging to keep thin applications of mortar moist while it cures, especially when it is in direct sun in the summer, so in theory the added fiber should help keep it from shrinking quite so much.

Thin 1” slab that held super well with vehicle traffic!
This stuff works. It makes a messy slab when wet, but a clean solid one once dry!
