Hi,new here,just discovered this site.Right now I am trying to plan this summers project,this will be drainage for our back yard so I can finally put up my shop.As we live at the bottom of a very large hill and we also have a natural spring in the yard I'm wandering if I could dig up the yard and layout a few rows of weep tile and lay them towards the bank as our property is about twenty feet above main street,then run them into a catch pit.If this is possible should I fill them in with crushed rock,also how deep should I go?We have a very large property for in town but I don't want to put the shop in the front side as it would ruin the look of the place,any ideas welcome thanks,Sid.
you need to dig deep enough to have a slope away from the shop building. Place at least 12" - 24" of gravel. Cover a 6" perforated drain tile covered with landscaping fabric to keep the pipes clean. Place the fabric over the gravel also. Cover the top with 1' gravel to cover the fabric and keep the gravel from washing away. Check with your building department, in many cases local ordinances prohibit water running from your property to be dumped into city property directly.
