    I was watching some British gardening show over the weekend in which they were installing a flagstone walkway and the contractor on the show was mixing in mortar with sand to set the stones in. Anyone ever try this? If so how'd it work? I couldn't really understand what the guy was saying so any info would be great.

    Thanks.

    Just keeps the stones from moving around less. Was it mixed morter or dry?

    when i did my paver install this summer (~900 sqft around my pool) my neighbor asked if i had swept in some mortar or concrete in the joints. He was tellin me one of his budd's had it done to keep grass/weeds growing up through as well as lock them in. But as i see it, most paver patterns won't allow any significant shifting. i don't think i'll have a problem with weeds in 12" of item #4 compacted @ 4" intervals either :)

    Pavers... no. Flagstone is irregular and not as closley spaced.

    He was mixing it dry. One brand of pavers recommends mixing mortar in with sand when building a tall retaining wall (4-8 courses). I'd never seen it used in flagstone work before.

    Sounds like he mixid in sand/portland cement mixture in the joints.

    From what i have seen you just lightly spray it down when finished and it hardens. Personally ive never seen flagstone move too much when put down on a good base.

    Maybe not, but they will grow in 8" done in 2" lifts, and they will grow in the sand that gets swept in. ;)

    We will mix in cement in with our 3/4 crush (for pavers) and wet it down if we feel the need.
