6 FIELD GUIDE TO SLAT REPAIR BEAM FAILURE INDICATORS Support beams are often the hidden source of catastrophic failures. Even when slats appear sound, compromised beams can lead to sudden collapse. Warning Signs: • Cracks forming above columns (most common failure point) • Moisture entering the beam, leading to internal rusting • Lower portion of the beam breaking away • One side looking intact while the opposite side shows exposed or protruding rebar • Separation or sagging along the bottom edges Rusting metal expands = Breaking concrete Causes the lower portion of the beam to fall off. A dangerous situation occurs as the structural integrity of the support lintel is compromised. Note circled area. The bottom of the beam has started to crack and separate. The damage has occurred even though the slats appear to be in good condition. How Beam Failure Progresses 1. Hairline cracks form above columns. 2. Moisture seeps through the cracks. 3. Rebar begins to rust. 4. Rusting metal expands. 5. Expanding steel breaks the surrounding concrete. 6. The bottom of the beam separates and falls away. 7. Structural integrity of the lintel is compromised → collapse risk. How to Inspect Beams Correctly • Shine a flashlight through slat openings. • Inspect both sides—one side may appear fine while the other shows damage. • Look for rust staining, swelling, flaking, separation, or exposed steel. If any bottom separation or protruding steel is visible, the beam must be replaced.
