Prior to laying synthetic grass careful base preparation is non-negotiable to ensure a long-lasting and professional result. First, eliminate all natural growth including turf, unwanted flora, root systems, and trash. Employ a turf cutter or garden spade to dig out the top layer of soil. This action stops regrowth beneath the synthetic layer and creates a debris-free foundation.

Once the area is clear, grade the surface with a landscape rake and a straightedge to identify uneven areas. Fill in depressions with compactable material like crushed stone or 熊本 人工芝 施工 gravel. Gradually reduce high points until the ground has a subtle gradient to channel runoff from structures and pathways.

Following surface uniformity, install a border or edging around the perimeter. This can utilize composite, steel, or cedar materials depending on your design.

Follow with a bedding layer of granular material about 5 to 8 cm in depth. Use a plate compactor to firmly press it down in sections. Repeat this process if needed to create a uniform, load-bearing substrate.

A top layer of premium silica sand can be laid as a finishing substrate for smoother grading and to help with drainage. Distribute it uniformly with a broom and gently tamp it down. Refrain from excessive irrigation here as it may lead to uneven compaction.

Check the surface again for levelness and make minor adjustments before proceeding.

Finally, ensure all utilities such as sprinkler lines or electrical cables are marked and protected. Restrict access to the prepared site until the turf is installed. Taking these steps carefully will reduce installation complications and maximize its long-term performance.
