When filled with sand and water the slabs will weigh 20kg per slab, with all 4 slabs weighing 80kg overall. To fill the slabs correctly we recommend filling each slab with kiln dried sand and then saturating with water.
The slabs themselves are made from HDPE resin which offers a weatherproof finish, allowing you to leave the slabs outdoors. Additionally, the slabs all come with their own individual carry handles, making it easy to lift the slabs and move them to the desired location. Plus, the steel links allow you to link the slabs together for full security of the parasol.
