Putting down synthetic turf on an old grass base is a popular choice for 熊本 人工芝 homeowners seeking a low-maintenance lawn, but it requires careful preparation to ensure durability and water flow. A common misconception they can simply install the synthetic surface without removal, but this results in costly mistakes like poor drainage, uneven surfaces, and rapid deterioration. The correct method involves eliminating the old turf and building a level substrate.

Start by removing every trace of plant life using a power sod remover or a heavy-duty shovel to extract the entire lawn including the roots. It is important to remove a minimum of 2–3" of soil along with the grass to achieve a uniform grading plane. Allowing old sod to remain will cause it to rot beneath the surface, leading to depressions and an uneven lawn.

Once the old grass is gone, contour the surface to ensure water drains clear of structures. Use a rake and leveling tool or a laser level to verify the gradient. A slight grade of one to two percent is ideal for drainage. After grading, press the base with a garden tamper or plate compactor to avoid sinking over time.

Then, install a base of aggregate material, typically 3–4" in depth. This layer enhances permeability and a firm foundation. Distribute uniformly and tamp it down firmly. Then apply a thin surface layer of clean, graded sand on top of the gravel. This fine aggregate helps form an even platform for the turf and ensures even infill coverage.

Before laying the synthetic turf, install an edge restraint around the entire installation zone. This prevents the turf from shifting over time and delivers a polished appearance. Unroll the synthetic grass making sure it is aligned properly and pulled taut to prevent puckering. Use a sharp carpet knife to cut to match contours, leaving a slight margin if needed for post-installation cleanup.

Secure the turf with landscape staples every 15–20 cm intervals along the boundaries and joints. If you have several sections, use specialized seam tape with glue to join them securely. Once the turf is in place, distribute infill uniformly—usually quartz sand or rubber granules—over the surface. Use a stiff-bristle brush or motorized brush to work the infill down into the fibers. This step provides ballast, maintains blade orientation, and extends lifespan.

Finish by lightly spraying with water to stabilize the material and wash away particles. Limit usage for the first 24 to 48 hours to ensure proper adhesion. Regular maintenance such as fluffing the blades and sweeping away litter will preserve visual appeal and performing reliably long-term. Correct setup is the essential for a long-lasting visually appealing fake grass that needs little maintenance.
