Large openings require different reinforcement than smaller ones:
Single Large Garage Door
A two-car garage with one wide door is more likely to develop stair-step cracks or visible gaps in the brick and mortar. Often, the original lintel is too small to bear the load, and reinforcement with steel beams, through-bolts, and underpinning is needed.
Double Garage Doors with a Center Column
For garages with two doors separated by a pillar, the footing must be strong enough to handle the extra load from brick or stonework above. If it’s not, cracks and bulges may appear, and the slab or masonry may need repair. Steel pier reinforcement often solves the issue.
