Frost Blanket
TERRAPRO™ Frost Blanket has been used successfully in renowned projects worldwide. It is installed horizontally to form a capillary break that prevents the rise of groundwater into the frost zone, thereby reducing the potential for damage as a result of the freeze/thaw cycle (frost heave).

FAQs
Terrapro thermally bonded nonwoven geotextiles are manufactured from polypropylene and polyethylene and offer a high strength-to-weight ratio, low moisture absorption, excellent durability and resistance to environmental conditions. These properties provide reliable performance and long-term protection in seasonal freeze-thaw conditions.
Key properties include permeability, tensile strength, moisture resistance, durability and service life. The appropriate grade should be selected based on site conditions, climatic conditions, soil characteristics and the anticipated severity of freeze-thaw cycles.
Terrapro Frost Blanket is installed horizontally within the road formation, between the subgrade and upper pavement layers. It is positioned above frost-susceptible subgrade to limit moisture migration and help prevent the freezing front from reaching moisture-sensitive soil. The installation depth should be determined based on-site conditions, soil characteristics and the anticipated frost depth.
Yes. The cost of providing and installing a Terrapro Frost Blanket can be significantly lower than the recurring maintenance and repair costs associated with pavement damage caused by seasonal freeze-thaw cycles. By helping mitigate frost-related damage, it can contribute to longer pavement service life and reduced maintenance requirements.
