Standard Grades
Don & Low manufacture a range of standard grade geotextiles suitable for use in a variety of civil engineering projects.
Lotrak® 609, Advance and 1800 are used to separate the sub base from the sub grade and prevent intermixing of construction layers, while maintaining the construction thickness. Expensive aggregates are therefore kept apart from the soil. These geotextiles also have a water filtration characteristic. The pore size of the geotextile is small enough to control the particle movement of the soil, but large enough to avoid clogging and maintain waterflow by creating a bridging zone to promote natural soil filtration.
Lotrak® 2300, 2800 and 4000 provides additional reinforcement function. Due to higher tensile strength and CBR values, these geotextiles can be used in areas where larger construction aggregates are required. Lotrak® 4000 has been designed as a high strength separator fabric, but also with high filtration characteristics.
