Prior to installing a gravel entrance, ______ should be placed on the ground.

Placing geotextile on the ground before installing a gravel entrance is a crucial step in the construction process. Geotextiles serve several important functions that enhance the long-term stability and effectiveness of the gravel surface. They act as a separation layer, preventing the gravel from mixing with the underlying soil, which can lead to erosion or settling. This separation is essential in maintaining the integrity of the gravel layer and ensuring adequate drainage.

Additionally, geotextiles can help to distribute the load of traffic over the area, reducing the potential for ruts and compaction of the subgrade soil beneath. This results in a more durable and functional gravel entrance that requires less maintenance over time. By promoting proper drainage, geotextiles also assist in reducing water accumulation, which can otherwise lead to erosion or damage to the entrance area.

Overall, installing geotextile before the gravel not only optimizes the entrance's performance but also extends its lifespan by mitigating issues caused by soil interaction and water drainage.
