Washington's climate, characterized by significant rainfall, means proper drainage is paramount for any concrete patio. We meticulously plan for water runoff, incorporating slopes away from structures and considering permeable options where appropriate. The soil type in areas surrounding Seattle can also vary, influencing the sub-base preparation. We ensure adequate compaction and the use of appropriate aggregate materials to create a stable foundation that resists moisture infiltration and settlement.
While Washington generally has less stringent permitting for basic patios compared to some other states, local regulations can still apply, especially in incorporated cities like Seattle. We stay informed about these requirements, navigating the necessary steps to ensure your project is code-compliant. Our process includes assessing the existing housing stock, which often features a blend of mid-century homes and modern constructions, ensuring our patio designs complement the architectural style and existing landscape of your Washington property.
