Web29 Jan 2024 · What is clay soil settlement? Settlement is the normal downwards movement that takes place as the soil beneath a new property compacts to adjust to the weight of the building. This occurs with clay soil as well. Settlement is normal in new buildings and is nothing to worry about. Webinstantaneous settlement results from elastic compression of clayey soil. For foundations on unsaturated clay or highly overconsolidated clay, the elastic settlement constitutes a significant portion of the total settlement. Immediate settlement ∆ V is estimated as: ∆ V = q x B x [(1 – γ 2)/E U] x I kevin haney colliers
