How much weight can drainage pipes handle?

There is Isocyanate-free foam.

Otherwise, caps would help; they are available for smooth ends as I assume you want to avoid the socket.

I assume these are the ones you mean?

Looks like the "lip" sticks out a bit, but you can probably file it down in the worst case. Should be able to solve the problem, yes.

You might have to let go of your favorite store concerning both foam sealant and plug, as the ones you linked to are for pipes with a muff. I wrote stos instead of muff because I couldn't remember what it's called.

After further testing, I can conclude that the tube actually flexes less than it feels.

Without pressure


With pressure



Right now, the flex is probably a plus, but later on, I will likely try inserting a tube inside. After all, I still have a larger part left

One option is to buy double-walled conduit which, as I understand it, is a bit more durable. Of course, it won't have a smooth exterior.

They seem to be intended to bend, which should not happen in this case.

There are plenty of other types of pipes that will handle the load. A thin road culvert that will be corrugated on the outside, or an SRE electrical conduit will handle the weight. However, it may be difficult to purchase these in less than 6-meter lengths.
