Home Concrete Slab With Fiberglass
I added this fiberglass to my concrete mix for a slab that was 3’W x 17’L x 4”D and it worked perfectly and made it super durable….

Fine quality but be ready to take time to pull apart the strands
The strands are a pain to pull apart enough so you get a decent mix without clumping. Quality seems decent

Fantastic FibreGlass product. I will order again
Absolutely what it says. I ordered what I got. I made a mistake thinking it was 5lb but it was actually 4lb. I am so sorry. The cut is good and the weight is correct. I will be ordering more in the future.
