To increase the effectiveness of the corduroy, prevent erosion,[3] and allow removal of material with less disturbance to the muskeg, a geotextile fabric is sometimes placed down before the logs. However temporary winter access roads on muskeg (ice road), created by clearing the insulating snow and allowing the muskeg to freeze, are more commonly used as they are cheaper to construct and easier to decommission. Water is often sprayed on these roads to thicken the ice allowing heavy trucks and equipment to safely access remote sites in the winter.[citation needed]
