6MM-1Lb Fiberglass for Cement Mortar Concrete Reinforcement Anti-Seepage and Anti-Cracking Cement Mix for Building Walls Garden Floor

Easy to blend in to the cement. Just sprinkle it into the dry mix and blend dry first, rather than throwing in a handful or dumping in the whole bag after you add the water. You'll also need to add more water than usual. Concrete seems very hard with the product added.

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.

Worked as advertised

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.

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
