Fixing sunken artificial grass is a manageable task that can restore the smooth, even appearance of your lawn. The process primarily involves accessing the affected area, preparing the necessary repair materials, and carefully leveling the sub-base beneath the turf.
Step-by-Step Guide to Repairing Sunken Artificial Grass
When artificial grass develops sunken spots, it's often due to the settling or compaction of the underlying sub-base. The repair process focuses on addressing this depression to bring the surface back to an even level.
1. Accessing the Sunken Area
The first critical step is to gain clear access to the depression beneath your artificial turf.
- Cut through the turf surface directly over the sunken spot. Use a sharp utility knife to make a precise cut, ensuring it's large enough to work comfortably within the affected area.
- Pull the newly cut edges back from the opening. This creates a "hole" that exposes the compacted or settled sub-base, allowing you to fill and level the area effectively.
2. Preparing Repair Materials
Once the sunken area is exposed, you'll need to prepare the specialized materials designed for artificial grass repair.
- Mix the materials in the repair kit together. These kits typically contain aggregates or leveling compounds specifically formulated to stabilize and fill voids beneath synthetic turf.
- Always follow the manufacturer's instructions for the specific mixing ratios and any required preparation steps to ensure the material cures correctly and provides durable support.
3. Applying and Leveling the Patch
With your repair materials ready, you can now address the sunken spot directly.
- Apply the mixed material to the cleared area. Carefully place the prepared mixture into the depression, ensuring it fills the void completely and extends slightly above the current level to allow for compaction.
- Use a trowel to spread the patch evenly. Work the material into the sunken area, compacting it gently and spreading it to create a firm, level base that matches the surrounding grade of the existing sub-base. The goal is to bring the depressed area back up to the original installation level of the artificial turf.
Essential Considerations for Repair
To achieve a seamless and lasting repair, keep these important points in mind:
- Identify the Cause: Before initiating repairs, consider why the turf sunk. Common reasons include improper sub-base compaction during installation, poor drainage, or heavy localized traffic. Addressing the root cause can help prevent future depressions.
- Specialized Kits: The "materials in the repair kit" are crucial. These are not just any sand or gravel; they are often engineered to provide proper drainage, stability, and compatibility with artificial turf systems.
- Tools: Ensure you have the right tools, primarily a sharp utility knife for precise cutting and a sturdy trowel for effective spreading and leveling of the repair material.
- Patience: Take your time with each step, especially when cutting and leveling, to ensure a smooth, unnoticeable repair.
