Build with Colour Polyproylene (pp) FIbres for concrete and screed 100-900g bags Reduces Shrinkage and cracking (900g x 12mm)

Worked well on a path that thinned out considerably. Remained solid and intact. Easy to use break it up / separate as small as you can ad it’s more effective

Great stuff!

Not great out of the box as just pieces of cut rope. The person suggesting using a vacuum cleaner to puff up the fibres is a genius. Works really well and quick to separate the fibres ready for adding to mix.

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.

Just what I wanted at the right price

Great product You don't need a lot, a few handfuls is enough. Best results with a cement mixer Loading water first, then half the sand Mix A handful or two of the fibres Mix again Then half the cement Mix The second half of the sand And cement Mix until fully blended Then pour

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!
