How Shuttering Secrets Are Destroying Rare Historic Buildings In the race to build faster, cheaper, and stronger, an often-overlooked construction technique is quietly threatening the survival of rare historic buildings: shuttering. Known commonly as formwork or shoring, shuttering is essential in concrete construction to support formwork during structural curing. Yet, when applied carelessly—or worse, reused without proper maintenance—shuttering practices are accelerating the deterioration of heritage structures across the globe. ### What Is Shuttering and Why Does It Matter? Shuttering refers to the temporary mold used to shape concrete until it gains sufficient strength. Traditionally made from plywood or metal panels, it plays a crucial role in ensuring structural integrity. However, in many cases, especially with aging or poorly maintained historic buildings, obsolete shuttering techniques are causing unintended damage. When outdated materials are reused without inspection, moisture traps build, leading to concrete degradation. Over time, this compaction weakens walls, undermines foundations, and accelerates spalling—especially problematic in century-old masonry crafted with delicate, non-uniform materials.
