Vermiculite Micafil 100 Ltr Pack Void Loose Back Fill Medium Grade flexible flue

The vermiculite was easy to use and handy to pour into the cavity.

Bought to mix with compost for my new build clay garden. Most plants are in pots for now, I repotted everything with 40-50% vermiculite/50-60% compost and everything is doing much better. Even though there's loads, I've just ordered a second bag as I've used up the first one. Very happy with the product. Also like the tip to use it as insulation for plants in winter, might try that too. :)

This is good stuff. I actually used this to insulate a Tandoor oven I built.Was delivered quickly and because I have loads left have been using as a mix in my raised beds.A multi use miracle product :)

Purchased this to seal a wood burning boiler flue that passed through a cavity wall. Followed instructions mixing with small quantity of water and packed out the void between wall and flue before rendering over with mortar mix. Once I got the consistancy right it held together nicely and did the job I purchased it for admirably and has created a safe fire proof job. Quantity was far more than I needed which was a double whammy as my wife seconded the surplus and is using it to mix with potting compost for her greenhouse plants as it is great for retaining moisture. Great multi purpose product.

Spot on for fireplace back fill when combined with cement

I bought this to mix a mortar back-fill to an iron fireplace. It IS a very large bag and will more than serve for the job I for which bought it. Happily I am also a gardener so will use up the rest in seed planting (but it may take many years to get through it all)Delivery was quick (and safe) tooHappy Customer here. Thank you.

Great product

Used it for insulating concrete at a 5:2:1 mix of Vermiculite: Cement: Sand and found the consistency just right for the job. You may want to experiment with the mix for whatever job you are doing with it. You definitely want something to hold it together unless you are burying it as it is very light and will blow away unless contained.It is so light you can pick up a 100Ltr bag with two fingers.
