Lotrak® separation geotextiles are used between the sub grade and sub base. This prevents intermixing of expensive stone and other aggregates within the soil, while providing good ground stabilisation.
Designed to control particle movement of the soil, Lotrak® separators, prevent clogging while maintaining water flow by creating a bridging zone to promote natural soil filtration. The main purpose of all Lotrak® separation geotextiles is to prevent the loss of construction gravel and aggregates into the underlying soil and/or subgrade.
