Response to Embeco machinist grout.......

I will add that while Embeco is great stuff, it isn't 100% foolproof (and neither is any of the other similar grout based expanding fillers that are mixed with water). If mixed wrong you will have a mess on your hands. Mix it way too thick & it won't pour for crap, and it will be hard to make it flow around the cylinders fully/evenly/correctly.

Mix it way too thin & it won't setup correctly and will be weak with top layers that can break loose/flake off easily. This is because a super watery mix has less total aggregate/filler in the mix (replaced by the extra water volume). The top layers in a thin/super watery mix in effect become little more than just mud & water, with most of what little filler material there is in the mix settling to the bottom of the waterjacket reducing the strength of the top layers.
