I am about to embark on my biggest DIY project to date.... building a garage/workshop/guest house from the ground up. I am intending on doing most of the work myself, hopefully the parts i am unsure about you guys can help me out with!!!
First issue I have is the plumbing in the foundation slab.
so it GENERALLY goes like this.
1 - Dig big hole
2 - Build Forms
3 - Backfill with gravel
4 - Compact gravel
5 - Add layer of sand
6 - Compact sand
7 - Add damp proof sheeting
8 - Add rebar
9 - Place concrete.
but i know i need to put some plumbing in my slab, so there are 2 questions.
1 - where do the pipes go? below the gravel? in the gravel? in the sand? in the concrete?
2 - where the pipes vertically penetrate the concrete (so i can connnect onto them in the house) do I need to protect the pipes in any way? or does the concrete come into direct contact with the pipe?
finally, I assume that whatever I do for in foundation plumbing, I can do the same for electrical conduit.
Thanks in advance for your help!!!
