Challenges of Black Cotton Soil
Black cotton soil expands drastically when wet and shrinks when dry, leading to seasonal foundation movement, floor tilting, and severe masonry cracking.
Engineering Solutions
- Deep Under-Reamed Piles: Extending foundation piers through black cotton soil into stable hard strata below.
- Sub-Surface Moisture Barriers: Installing impervious plastic aprons around the building perimeter to prevent soil moisture fluctuations.
- Jack Leveling & Base Anchoring: Lifting settled building corners back to level before pouring reinforced footing jackets.
