Routavaipan

Routavaipan is a Finnish term that translates to "frost cloth" or "ground cloth." It refers to a protective layer of material, often made of geotextile fabric or plastic sheeting, that is placed over soil to prevent or mitigate frost heave. Frost heave occurs when water in the soil freezes, expands, and pushes the soil upwards. This can cause damage to foundations, roads, and plants.

Routavaipan is typically used in construction and landscaping to protect structures from frost damage. It is laid down before the ground freezes or before construction begins, and it remains in place to prevent water from infiltrating the soil and freezing. In gardening, it can be used to protect sensitive plant roots from freezing temperatures, especially during winter. The material acts as a barrier, preventing moisture from reaching the soil or, in some cases, allowing for controlled drainage to reduce water content. The specific type of material used can vary depending on the application, with geotextiles offering breathability and durability, while plastic sheeting provides a more impermeable barrier. Proper installation is crucial to ensure its effectiveness in preventing frost heave and its associated damage.
