WICK DRAINS AT MALTON BY-PASS

The article describes the UK introduction of vertical wick drains in the construction of the malton by-pass in North Yorkshire. This type of drain is intended to accelerate the process of the consolidation of soft alluvial deposits under embankment loadings. This consolidation is defined as volume decrease caused by escape of porewater under excess pressure. Originally developed in Holland, the wick drain is a non-woven polyester fabric resistant to all acids and basic chemicals found in soils. Its pore volume in excess of 80% accounts for the fabric's high water transmissibility. The wick itself is 300 mm wide, 4 mm thick and is supplied in rolls up to 300 M long. /TRRL/
