You’ve invested in a premium chemical-resistant lining. The specs are solid. The installation was flawless. But five years in, it’s cracking, delaminating, and breaking down.

At Crescent PPG, we’ve seen this scenario play out too often. The culprit? Not the lining—but the concrete beneath it.

In one pulp mill case, a reinforced novolac vinylester lining failed prematurely. Our investigation revealed the real issue: high-alkali cement triggering Alkali-Silica Reaction (ASR). The concrete expanded, fractured, and disbonded the lining from below.

This is reactive concrete failure—and it’s not just a legacy problem. We’ve seen it hit brand-new builds.

✅ Before you install any lining system, ask:

• Has the substrate been tested for ASR?
• Are you using low-alkali cement and non-reactive aggregates?
• Is your concrete mix designed for long-term chemical exposure?

Petrographic analysis, core testing, and lithium treatments aren’t optional—they’re strategic.

If you’re planning a new tank farm, chemical containment zone, or industrial flooring system, let’s talk. Crescent PPG doesn’t just protect surfaces—we protect your investment from the ground up.
