I will be completing a paver wall and patio this summer and had a few questions: - Will a wet tile saw work well on the patio blocks? - What is the best tool to RENT for cutting 4" thick retaining wall block? I see wet tile saws, a gas-powered 12" hand held saw (looks like a miter saw, but handheld), or the guillotine non-powered type? - I am in the Detroit Metro area and there isn't a standard 'sand' used for inbetween the pavers. A contractor used slag sand (same as the base) for my front walk but sometimes the pieces are too big, so walking barefoot...ouch. Unilock and HD sells bags of 'jointing sand' but neighbors have the problem of that washing away quickly. Thanks!
