Concrete Trench for Sulphur

Concrete Trench for Sulphur

Concrete Trench for Sulphur

(OP)
I have a small concrete trench carrying molten sulphur(steam heat pipes in bottom of trench). I understand the temperature is approx 150C The trench is buried in the ground and I want to minimise groundwater contact with the concrete. EPDM is good for about 110C.

Can anyone suggest a relatively inexpensive membrane that can be used to prevent water from reaching the concete?
