The technique of installing prefabricated wick drains is well established in Europe and Japan, but is relatively new to North America. This paper describes the use of piezometer cone data to predict the performance of wick drains in a soft clayey silt in Burnaby, British Columbia. A description of the testing procedures and the theory to calculate the rate of consolidation are briefly presented. The predicted rate of consolidation using the piezometer cone data and the measured performance is compared and discussed; good agreement between the two was found.Key words: wick drains, piezocone, prediction, preload, settlement.
