Concrete Surface Lining

Concrete Surface Lining

(OP)
As I understand from standards, Coating and Lining are two different techniques. HDPE falls under lining.

Our client has a chemical drain pit with NaOH, HCL, NaOCL, NaHSO3 and other inorganic chemicals. We have advised to put HDPE lining on the concrete surface to protect the wall surface. We have observed failure of an existing pit with similar chemicals.

We have also received a suggestion to use HDPE tank supported by concrete structure for the pit.

Advise a suitable material for coating or lining.
