Stabilize expanding and contracting soils beneath your home

Expansive clay soils shift as moisture levels change, swelling when wet and shrinking during dry conditions. This constant movement can place stress on your foundation, leading to cracks, uneven floors, and structural instability. In Hawai‘i, these cycles are often intensified by varying climate conditions, making early stabilization critical to protecting your home.

Structural Systems evaluates soil composition, drainage, and moisture patterns to design targeted stabilization solutions. By managing how water interacts with the soil and improving ground performance, we reduce the expansion and contraction that causes foundation movement. Each system is engineered based on site-specific conditions to deliver consistent, long-term support beneath your structure.

Our stabilization approach focuses on controlling the factors that drive soil movement. This often begins with improving drainage to prevent excess water from saturating the soil. By redirecting water away from the foundation, we help reducethe swelling that occurs during heavy rainfall.

Frequently Asked Questions

What are expansive soils and why are they a problem?

Expansive soils are clay-based soils that swell when wet and shrink when dry. This constant movement can shift your foundation, causing cracks, uneven floors, and structural stress over time.

How do you stabilize expansive clay soils?

Stabilization focuses on controlling moisture and improving soil behavior. This may include drainage improvements, moisture barriers, or soil treatment methods that reduce the soil’s ability to expand and contract.

Is this a permanent solution?

When the soil is properly tested, expansive soil stabilization provides control of soil movement. This solution helps balance the ground moisture beneath your home.
