Fiberglass for Cement Mortar Concrete Reinforcement Anti-seepage and Anti-cracking Cement Mix for Building Walls Garden Floor 3/4"(19MM)-1lb/PACK

Added to several bags if drum mixed concrete for added crack resistance. I have used this product many times and it's well worth it IMO.

These fibers came in a zip lock bag that makes resealing very nice.Fibers worked great for me when I mixed with 60lb bag concrete.

This shredded fiberglass mixes well with most all concrete products and does not clump up. Really adds an extra level of durability and strength to concrete installations. Recommend this product. In some cases there is no need for rebar if the concrete application is suitable for this alternative.

So, I think this will be okay for my concrete project but man, it was hard to mix. It burned out my drill so, make sure you keep adding water and have some help. It was also really clumpy in the beginning. I think I’ll stick with rebar bars or rebar mesh.

I add the fibers to the hypertufa mixture when I make pots. It strengthens the pot so happy with it. I do recommend using a blow torch (after the one-month drying period) to remove the fibers on the surface.

I added this to my concrete mixture to reinforce my work. It worked out great. I make huge leaves with it for my landscaping

Just what I wanted. I really like the fiberglass in concrete

I use this product for making my concrete leaves and other items. Seems to work well, I have some that are quite old and still holding together. Other than pulling the fibers apart it's easy to use.
