Selecting Long-Lasting Pavers

Your patio must withstand Sammamish weather resistance—think seasonal rain, freeze-thaw cycles, and moss growth. That’s why permeable pavers are a top pick for residential hardscaping. They shift slightly without cracking, thanks to proper sand bedding and edge restraints.

• Opt for more compact pavers in high-traffic zones
• Ensure sub-base includes compacted aggregate

A landscape designer can help match your stone selection to your home’s style and the site’s exposure. Proper sealing further enhances longevity and stain protection.
