[MW:30091] concrete base in destilation tower

Dear Group,

Please consider attached pictures.

This is a de butanizer tower in cryogenic gas process unit.

Due to low process temperatures, and even with isolation, there´s ice that is created in some sections of tower and it´s pipes.

Ice blocks, with some environment conditions, begins to melt in form of water drops, which falls from a high altitude and hit concrete base of tower.

As you can see, concrete base has damages due to impact of water drops.

Now, our theme is determinate which steps we could follow to recover the concrete base to original conditions.

I´d like to know is it´s necessary a civil engineering develop which could determine action to take.

Please if you can give me some references of your experiences or codes/standars to manage this kind of cases

Thanks in advance

Best regards
