Foundations on Expansive Soils in Northern Virginia

by Lawrence C. Rude, Soil Consultants Engineering, United States,
Farshad Amini, Soil Consultants Engineering, United States,



Document Type: Proceeding Paper

Part of: Foundation Engineering: Current Principles and Practices

Abstract:

Thick layers of clayey silts (MH) were observed at several sites where townhouse developments were planned. These deposits had a high shrink swell potential. Maximum swell pressure tests and shrinkage tests were performed in a consolidometer to determine the shrink swell characteristics of these soils. The laboratory results were used to determine the amount of clayey silts that were needed to be removed from beneath the townhouses and replaced with non-swelling compacted/controlled fill.
