Precision Barrier Design and Maintenance Workshop (PDI) Precision barrier systems rely on material science fundamentals—compression strength, thermal expansion, and fatigue resistance all factor into design longevity. Walk in knowing how environmental stressors degrade different substrates, why maintenance intervals vary by installation type, and how regulatory load-bearing standards shape barrier specifications. Gaps here compound downstream.
