Soil conditions beneath concrete are just as important as the concrete itself. In Calgary, clay-heavy soils and seasonal moisture changes can cause shifting and settlement if not addressed properly. Understanding soil behavior is key to long-lasting concrete performance.
Why Soil Preparation Matters
Unstable soil expands and contracts with moisture and temperature changes. Without proper preparation, this movement transfers directly to the concrete slab, leading to cracking and uneven surfaces.
Key Soil Preparation Steps
1. Excavation: Removing unstable soil layers.
2. Gravel Base: Creating a stable, drainable foundation.
3. Compaction: Preventing future settling and movement.
4. Grading: Directing water away from the slab.

“Most concrete failures start below the surface. Proper soil prep is the foundation of every durable concrete project in Calgary.” – Lion Heart Contractors Team
By addressing soil conditions before pouring, concrete surfaces remain level, strong, and reliable for decades.
