Hey all Don't know if this would be the right section to post this question or not but I'm wondering what the difference in crush rating is between schedule 35 & 40 PVC vs. black dual wall plastic tile? I have a job to do for a customer - it's a septic outlet and it runs thru a farmers "hilly/ rolling" field. Some areas will only have a foot of cover (Hence the crush rating question)
Please don't start multiple threads in different sections asking the same question, discussion is at this thread. >
