Problem: Customer has a large concrete sump that they dump chemicals and waste into. The concrete has cracked over time. They were looking for a repair method to seal the cracks to prevent liquid from inside going out, and vice versa. They previously repaired cracks using Belzona system and it held well for many years. There were additional areas that had not received Belzona that needed to be addressed. After an inspection, the report showed a few cracks that were greater than 1/8” wide and needed repair.
