In the process of leveling the family back yard for pavers and nice rock. Not my area of expertise, but it is coming along nicely. Started out with nasty clay/dirt mix that made the back yard unusable any time it rained. So far we have only done the foundation work of killing grass, laying a thick layer of crushed concrete/limestone mix to level it out, and added some sand to help solidify the rock. How long do you think I should wait for this foundation to settle before we finish up with the pavers and nice rock? Definitely a work in progress, but the weather is nice here in Texas (for how long?) so the more work we can get done this season the better.
