Polyproylene (pp) Fibres for Concrete and Screed 100-900g Bags Reduces Shrinkage and Cracking (900g x 12mm)

Great productYou don't need a lot, a few handfuls is enough.Best results with a cement mixerLoading water first, then half the sandMixA handful or two of the fibresMix againThen half the cementMixThe second half of the sandAnd cementMix until fully blendedThen pour

I use this stuff for all sorts to make my mix very strong, it's used throughout the building trade and tons of tests using rebar and this product and this if not better than rebar.The stuff I recommend using it for:StepsRepairsScreeds, but if you use bal max as they have fibres in them, but good for cement screeds that you mix yourself.DrivewaysGarage floorsCar basesPaving slab makingand many more ideas available on YouTube.

Having worked in a factory that made this, it is great, Ok it will not work for a bridge without steel, It works on slabs 2 to 3 meters square.

Saw these reinforcing fibres on a youtube video on fillet pointing. My previous attempts at pointing ended up cracking and flaking within 12 months. These are a bit of a faff as they require separating by hand which is rather laborious but worth doing before you try and mix them in as the mixing process itself does little to separate out the clumps. A little goes a very long way - my mortar was positively "hairy" but they're not visible in the finish. I'll never use all these in my lifetime but they seemed priced very keenly and delivery was extremely quick so it was worth getting more than I needed in order to get them quickly.

Have never used before personally but have seen it used on construction sites in the screed.Very difficult to work out how much to add to my concrete mixer so just guessed by grabbing a small amount and bunging it in the dry mix.Lots of fine fibres floating about in the air during mixing so my lungs are probably full.I wasn’t sure if I had used enough as I bought 2 bagfuls of 900g for 2 cubic metres but ended up with two thirds of a bag left.However I noticed that on washing out and embedded in the waste concrete the fibres were well embedded. I broke open the waste concrete and the fibres seem to be embedded throughout. One final point I broke up the waste lumps after a few days and it was very difficult - the concrete just wouldn’t split apart so I think the fibres are doing their job really well. Would definitely add to any future screed or concreting project.

I have a few holes - big and small - in my inclined hardcore/gravelled drive. Typically, when patched, the concrete gradually breaks up.I dropped a bag of this in the mixed and so far the resulting patch is showing zero signs of cracking or break up despite weeks of both rain, hot sun and normal traffic with SUVs and 4x4s. Definitely give it a go if you have the same problem. I understand the basic mechanics./physics but was still surprised by how well it seems to work!

Good product

Disapointed with this product as the fibres are obviously cut to length in bulk and are then clumped together. Difficult and time consuming to separate when adding to the concrete mix resulting in the odd clump of fibres floating to the surface when stamping. Would not buy again
