Adjustable paver pedestals are a system used to support bricks, pavers, stone slabs, and even wood on flat surfaces such as rooftops or terraces. They are typically made of plastic and feature adjustable heights, allowing for easy adjustment of the height and level position of the pavers as needed to ensure a flat, stable, and safe surface. Adjustable paving pedestals are commonly used to prevent water from pooling on rooftops or terraces and provide better drainage. Adjustable pedestals for paving can also help to isolate noise and vibration and in some cases may be used as cable channels.
