Tank & Containment Lining
Secondary Containment Polyurea Lining
Chemical-resistant polyurea lining sprayed over a concrete containment berm to meet code and protect the structure.
The Challenge
A concrete secondary containment berm was cracking and no longer met containment requirements for the chemicals stored inside it.
Our Solution
We abrasive-blasted the concrete, primed it, and sprayed a seamless chemical-resistant polyurea lining up the walls and over the floor, coving all transitions. The lining was holiday-tested for pinholes.
