The area that you need covered with the gravel or loose fill paving will depend on the specific needs of your project. It is important to choose a paving material that is both durable and weatherproof, so it is important to consider the climate in which you live and the traffic that will be using the surface. If you are looking for a temporary surface that can be easily replaced or removed, then loose fill paving may be a good option. Loose fill surfaces are typically composed of gravel, crushed stone, or recycled glass and can be installed over most existing surfaces without too much preparation. However, they do not offer as much durability as other types of paving materials and are not recommended for high traffic areas.

The area you need covered with the gravel or loose fill paving is up to you. It can be a small area, such as a patio, or it can be a large area, such as a driveway. If you're looking for an easy way to cover an area with gravel or loose fill paving, consider using paving stones. Pavers are designed to be used as a paving surface over gravel or other loose fill materials like sand and dirt. Not only do they provide an attractive finished look, but they also help to stabilize the surface and keep the gravel in place.
