steel lined vs. protective layer on drain

[Luk]

Hi there!

I have an open drainage system made of concrete. It is located on the ground level of a building.
The issue is that the ground around the drain is heaving, causing the existing steel lines to 'peel' out of the drain.
I'm thinking of using concrete protective layers in replacement of the existing steel lines.
The drain has to withstand discharge of high temperature, acidity and alkalinity.
Any thoughts on this matter?
Thanks!

Cheers,
Luk
