What foundation is needed for heavy granite outdoor armchairs?

When installing heavy granite outdoor armchairs, a strong and stable foundation is essential to prevent sinking, tilting, or damage over time. Here’s what you need:

1. Concrete Slab or Pavers: A solid, level concrete base or interlocking pavers provides excellent support for granite armchairs, distributing weight evenly.

2. Gravel and Sand Layer: For areas with drainage concerns, a compacted gravel and sand layer beneath the foundation helps with stability and water runoff.

3. Reinforced Footings: In softer soil, deep concrete footings with rebar reinforcement ensure long-term durability.

4. Adjustable Base Plates: For uneven surfaces, consider using adjustable metal or plastic leveling pads to keep the chairs stable.

Always check local soil conditions and weather patterns to choose the best foundation method for your granite outdoor furniture. Proper installation ensures safety and longevity.
