Reduced soil compaction: Heavy foot traffic, mowing, and other activities can compact the soil over time. Aeration loosens the compacted soil, improving its ability to absorb water and nutrients.

Enhanced water infiltration: Aeration helps prevent water runoff by improving the soil’s ability to absorb water. This reduces wastage and ensures that your lawn receives maximum hydration.

Promotes thicker turf: By alleviating soil compaction and providing better nutrient absorption, aeration encourages thicker grass growth, resulting in a lush and vibrant lawn.
