Clay channel repair Drainage and wastage systems and plumbing help, advice and answers

[RuLidd]

Hello,

I am new to the forum so hope this is posted in the right place.

I'm looking for some advice on a repair of a section of clay channel that is set in a old concrete inspection chamber. The channel section has cracked into a number of loose pieces on a bed of water saturated soil.

I believe the rest of the drain is sound and the waste flows well. However water is seeping into the ground with every flow.

I think I can source a replacement section of channel but I'm not sure how it should fitted. Should it sit on a particular bed? Should that be mortar, concrete or some sort of compacted aggregate?

Assuming mortar will needed to fix and point the channel, does it need to be a particular mix?

Any other any advice for carrying out the work would be helpful.

Cheers
R

Hi rulidd,
Dig out the bottom of the chamber, cast a concrete base, lay your new section of pipe on/in it and render around it with a sharp sand + cement mix.
