Loosen compacted soil so water, air, and nutrients can reach deep into the root zone.
Calgary's clay-heavy soil compacts easily under foot traffic, freezing, and thawing cycles. When soil is too dense, roots can't penetrate deeply, water pools on the surface, and fertilizer never reaches where it needs to go. The result: a shallow, weak lawn that struggles through summer heat and drought.
Core aeration uses a machine to pull small cylindrical plugs of soil — called cores — out of the ground across your entire lawn. The holes that are left behind allow air, water, and nutrients to move directly into the root zone. As the plugs break down over a few weeks, they help condition the soil and reduce compaction long-term.
We recommend aerating once a year in either spring or fall. It's one of the highest-return treatments you can do for a Calgary lawn, and it pairs exceptionally well with overseeding and fertilization applied immediately after.
Breaks up compacted soil — roots can finally grow deeper and access the nutrients they need
Improves water absorption — stops pooling and runoff, every drop reaches the root zone
Boosts fertilizer effectiveness — nutrients go directly into the soil instead of sitting on top
Reduces thatch buildup — microbes in the cores help break down the thatch layer naturally
Stronger, deeper roots — leads to a denser, more drought-resistant lawn all season long
