Weather-Resistant Hardscape Choices

Selecting Long-Lasting Pavers

Your patio must withstand Sammamish weather resistance—think heavy 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 less porous pavers in high-traffic zones
• Ensure sub-base includes compacted aggregate

Rainproof Paving Materials

Not all stone performs well in wet climates—limestone can degrade, and sandstone may spall. For true Sammamish weather resistance, go with bluestone, which resist moisture absorption and surface erosion.

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.
