Stone dust is a fine material that absorbs moisture readily, then releases it slowly. The same properties that work wonders for organic gardening can wreak havoc underneath pavers, causing efflorescence and allowing them to settle or shift easily under load. In extreme frost-thaw cycles, water-soaked stone dust can actually pump up through the ...

Southies. 21/10/2017. DH refuses to add cement to the crusher dust/ crushed granite we will be laying down the side of our house along with pavers. His argument is that it will cause all kinds of access problems should we need to get to our plumbing, which is directly underneath. It's not as though we will be laying down a concrete slab.

Nova Scotia, Canada. For soil cement the CRUSHED gravel should have poper mix of fines to larger pieces to make it as dense as possible. Add the proper amount of cement and water and mix well by some mechanical means, smooth to grade and pack it. The mix is not a slurry and is very hard to tell from damp gravel.

2. Add a small amount of water. There is no precise amount of water to add to your cement. You merely need to add enough that you form a smooth paste with the consistency of peanut butter. Start small to avoid creating cement that's too soupy. Pour a small amount of water, like half a bucket, into the crater you made.
