Soil Preservation
Avoiding excavation preserves the existing topsoil and its microbiome. For very short-term applications, this keeps the option open to restore natural grass later.
Potential Issues to Consider
Understanding what artificial turf is made of helps explain why direct overlay creates challenges for permanent installations. Synthetic fibers are stitched into a flexible, perforated backing that needs solid support.
Decomposition and Settling
Living grass deprived of sunlight dies and decays. As organic material breaks down, it loses volume and creates voids. The turf settles into these gaps, resulting in an uneven, bumpy surface.
Drainage Problems
Decomposing grass can mat into a barrier that traps water between the backing and soil. Standing water breeds mold and bacteria, and once that smell sets in, it doesn’t go away on its own.
Surface Instability
Without a compacted base, the lawn feels spongy and the turf shifts underfoot. Wrinkles and dips follow.
Weed Breakthrough
Bermuda grass doesn’t die easily. It can go dormant under the turf and push back through drainage holes or seams months later.
For permanent installations, stripping the grass and building a proper base eliminates these problems before they start.
