Picking Resilient Surfaces

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

Patio Project Inspection Points

Patio Installation Process

Initial Project Setup

Proper site prep is the foundation of any durable outdoor flooring. This includes removing vegetation, debris, and old materials, followed by professional grading to ensure water flows away from your home. Poor prep leads to pooling, erosion, and foundation issues down the line.

• Identify utility lines before digging
• Excavate 6–8 inches of soil for base depth

Foundation and Leveling Techniques

A solid base of compacted gravel and sand prevents shifting and sinking. For Sammamish’s clay-heavy soils, proper compaction and layering are essential for frost heave prevention. Certified hardscape installers use laser levels and hand tools to achieve perfect pitch and alignment.

Grading for Water Runoff

If your yard slopes, improper drainage can send water toward your home’s foundation—costing you thousands in repairs. Solutions include perforated pipes to redirect flow. These are integrated during installation for seamless performance.

• Install underground pipes
• Angle surface away from structure at 1/4 inch per foot
