ABSTRACT:
A method for preventing or greatly reducing damage to building foundations resulting from the swelling of moisture-expansive clay beneath and about such foundations. The method includes the steps of first forming a trench about the foundation, the trench extending well below the basement or on-grade floor slab of that foundation, and then substantially filling the trench with an extrudable plastic mass of hydrated lime and water to help stabilize the moisture-expansive clay and to provide a yieldable buffer capable of being displaced upwardly to accommodate horizontal expansion of the clay beneath and about the foundation, thereby relieving lateral stresses and reducing upward forces against the floor slab.
