Which method stabilizes formwork during masonry construction?

• A. Shims And Wedges
• B. Ties And Spreaders
• C. Nails And Bolts
• D. Adhesive Straps

Answer: (B)

Maintaining the shape and spacing of formwork under the pressure of wet masonry mortar is essential. Ties and spreaders connect opposing formwork panels, pulling them together and keeping them at the correct distance apart. This resists the lateral thrust from the fresh masonry as it sets and helps keep panels aligned and plumb, preventing bulging or misalignment. Spreaders hold the formwork at a precise width, while ties transfer the forces across the wall so the panels stay in their intended position. Shims and wedges are useful for leveling or fine-tuning individual panels, but they don’t provide continuous restraint against the overall wall thrust. Nails and bolts can fasten panels but don’t inherently manage lateral pressure and can loosen under load. Adhesive straps aren’t standard for stabilizing masonry formwork and don’t offer the rigid spacing control and load transfer that ties and spreaders provide.
