Large stone sculptures require robust structural supports to maintain stability and prevent damage over time. The most common supports include metal armatures, concrete bases, and hidden reinforcement systems.

Metal armatures, often made from stainless steel or bronze, provide internal stability for intricate designs. These frameworks are embedded within the stone during carving, offering strength without compromising aesthetics.

Concrete foundations are widely used for outdoor sculptures, anchoring heavy pieces securely to the ground. Properly engineered bases distribute weight evenly and protect against shifting soil or weather conditions.

For delicate sculptures, hidden reinforcement techniques like dowel pins or epoxy resins create invisible connections between stone segments. Modern adhesives allow conservators to repair cracks while maintaining original appearances.

Understanding these support systems helps artists create enduring works while preserving cultural heritage through proper structural engineering.
