A Lightweight Soil Nail Retaining Wall in Unsaturated Clay

Hence the clay is unsaturated and stiff or very stiff. Unsaturated soil mechanics allow the design shear strength of this clay to be estimated with sufficient confidence for engineering purposes. This shear strength is significantly greater than that formerly used in conventional retaining wall and revetment design when suction is …

Boundary Wall design for clay soil on a hill

Clay soil deeper down in the ground is less susceptible to moisture changes and so tends to stay the same volume and hence doesn’t shrink/expand and ‘heave’ If you want a boundary wall that won’t crack, built on clay, you need to dig a deep enough footing. 1 metre is usually sufficient, providing that …
