5 BEARING SURFACE REQUIREMENTS • Bearing Requirements: Hog Lintel beams require a minimum 3-inch full width bearing on square columns and 4 inches on round columns, per engineering specifications. • Buildings can shift over time—especially at end walls— causing beams to slide partially or fully out of pockets. • If a beam is not fully seated, remove slats and beams and correct the structural support before reinstalling. • Uneven, dipping, or rocking slats often indicate a beam has begun to slip. IDENTIFYING UNREPAIRABLE SLAT DAMAGE Signage of Beam Misalignment The appearance of uneven slats can be an indication of a beam starting to fall from a column or end wall pocket. At least 4” of bearing surface should be present on a column or end wall pocket • Slats appear uneven or dip across a span • Slats lift or rock underfoot • Visible shifting where beams meet column or end‑wall pockets UNREPAIRABLE SLAT DAMAGE 1) Underside Cracking (~2 inches above base) • Indicates moisture penetration and rusting rebar. • Expanding steel fractures the concrete from the inside out. • These slats cannot be reliably repaired and must be replaced. 2) Top‑Surface Cracks (Isolated) • If moisture has not reached the steel, epoxy products can stop progression and prevent corrosion. • Suitable only for early‑stage, non‑structural top cracks.
