Residual water? 3Jul 11, 2011 10:14 pm thanks bashworth.... so having the residual water around the (as there would be some left over after rain or watering) is ok around the the slab location? and what is the reasoning behind having smaller stones around the pipe?

Residual water? 4Jul 11, 2011 11:03 pm If the pipe is at the bottom of the trench the residual water will be minimal and as long as the underside of the slab is protected there shouldn't be a problem. The smaller gravel will 1.Provide better support for the pipe 2.Filter out fine dirt that gets washed through the larger stone, keeping it out of the pipe The Harder You Try - the Luckier You Get !
