Health and beauty are root deep.  Over time, the soil beneath your lawn gets compacted, which impedes root growth. Compact soils prevent grass from establishing a healthy root system and keeps air, water and fertilizer from reaching the roots. Common causes of compaction include:

• Foot traffic
• Lawn maintenance
• Heavy rains
• Clay soils

For a beautiful, healthy lawn you need to get air, water and nutrients down through the thatch and soil to the root zone. Aeration makes this possible.
