What are the best granite weight distribution techniques?
Granite is a popular choice for countertops and other surfaces due to its durability and aesthetic appeal. However, proper weight distribution is crucial to prevent cracking, sagging, or structural failure over time. Here are the best techniques to ensure optimal granite weight distribution:
1. Use Adequate Support Structures – Thick plywood or steel reinforcements beneath the granite slab help distribute weight evenly, especially for large spans like kitchen islands.
2. Install Support Brackets or Corbels – For overhangs exceeding 12 inches, brackets or corbels provide additional stability and prevent stress on the edges.
3. Opt for Thicker Slabs – Thicker granite (2-3 cm) naturally handles weight better, but for extra-long surfaces, consider laminated (3 cm with plywood backing) or reinforced slabs.
4. Proper Sealing and Leveling – Ensure the base cabinets or support framework are perfectly level to avoid uneven stress points that could lead to cracks.
5. Avoid Excessive Overhangs – Limit unsupported overhangs to 10-12 inches unless additional reinforcement is used.
By implementing these techniques, you can enhance the longevity and safety of your granite installations while maintaining their beauty and functionality.
