Hog Slat - Field Guide to Concrete Slat Repair and Replacement

3 LEVEL 1 - LIGHT WEAR (MONITOR) • Common around feeders and waterers due to high traffic and acidic conditions. • Indicates normal aging, not poor‑quality slats. • Action: Continue monitoring; consider protective coatings. LEVEL 2 — MODERATE WEAR (PLAN) • 1/4”–1/2” wear with rough texture or lightly exposed aggregate. • Counts toward the 40% replacement rule. • Action: Plan replacement timeline; monitor for emerging cracks. LEVEL 3 — SEVERE WEAR (REPLACE NOW) • Deep pitting, exposed steel, or broken edges that widen gaps and create pig‑leg entrapment risks. • Large numbers of Level 3 slats indicate the need for partial or complete slat replacement. • Action: schedule replacement; inspect support beams closely for concurrent failures. DAMAGE LEVELS EXPLAINED Reminder: Damage levels help guide planning, but structural red flags override wear levels and require immediate action.
