What foundation is needed to support a heavy stone outdoor sofa?

A heavy stone outdoor sofa requires a strong and stable foundation to ensure durability and safety. The ideal foundation should distribute the weight evenly to prevent sinking or shifting over time. Here are key considerations:

1. Concrete Slab: A poured concrete slab is the most reliable option, providing a flat and sturdy surface that can handle the weight of stone furniture.

2. Gravel Base: For a more flexible solution, a compacted gravel base with proper drainage can support the sofa while allowing water to flow away.

3. Pavers or Flagstones: Large, flat pavers or flagstones set on a leveled sand bed offer a decorative yet functional foundation.

4. Reinforced Footings: For uneven terrain, reinforced concrete footings can anchor the sofa securely.

Always ensure the foundation is level and properly prepared to avoid future instability. Proper support will extend the lifespan of your stone outdoor sofa and enhance its aesthetic appeal.
