Total weight of the 4 modules (approx.): Empty weight: 5.2 kg, filled with water and sand: 80 kg. A solid base is essential not only in construction or when consuming alcohol, but your sun umbrella also benefits from a secure stand. But why buy a parasol base when a foot cross is already included in the delivery? The standard foot crosses usually serve one purpose: they keep the umbrella upright - as long as there are no external influences. As soon as the wind picks up or other dynamic forces act, your sun umbrella is off and leaves a trail of destruction. Wind, in particular, should not be underestimated, as even smaller umbrellas can have a canopy area of almost 10 m², which is equivalent to a medium-sized sail. Robust and easy to assemble, this parasol base, thanks to its clever modular system, is just as easy and space-saving to store away while still providing enormous stability. Please note: The parasol base should be filled with sand or a mixture of sand and water. It is advisable to fill the base with water, sand, and gravel to make it heavier. We also offer additional parasol bases with even higher weights for greater requirements. A general rule of thumb for better stability is: Umbrella up to 2 m: approx. 20 kg, umbrella up to 3 m: approx. 40-50 kg, umbrella up to 4 m: approx. 80-100 kg, umbrella up to 5 m: approx. 125-150 kg. Calculations like 1 kg per 10 cm diameter are certainly not accurate, as they do not take into account that the umbrella area increases exponentially. Additionally, the area of the parasol base and the height of the umbrella are also important. Brand owner TÜV-Süd QM ISO 9001 certified with No. 12 100 59626 TMS for quality management in Germany.
