What base do we need for our surface?
It depends on the ground and how exposed the site is
Concrete or solid paving
A bolt-down base plate fixed with expansion anchors. The most stable option, and what most restaurant and hotel terraces use.
Timber decking
A through-fix plate bolted into the joists below, or a heavy weighted plate if drilling isn't allowed. Never put a light base on decking — wind will tip it.
Grass or open ground
A cross base or a ground socket, loaded with pavers or a dedicated ballast block.
Balcony or rooftop
Weighted plates only, sized to the umbrella and the wind load at that height. We'll calculate the required weight for your site.
Windy or coastal sites
Heavier ballast plus reinforced ribs. On exposed sites we also recommend closing the umbrella whenever the venue is unattended.
A simple rule of thumb
The bigger the canopy, the heavier the base — a 3 m umbrella typically needs around 40–50 kg, a 4 m cantilever 100 kg or more. We'll confirm the exact figure for your model from our spec sheet.
Tell us three things and we'll specify the exact base: the ground surface, the model you're considering, and how exposed the site is to wind.
Base by surface type
The right base depends on your surface. On concrete or wood decks use a plate or fillable base. On grass or sand use an in-ground anchor or a peg base. On tiled or rental terraces where drilling is not allowed, choose a heavy portable or split base.
Matching to model
Tell us the surface and the umbrella model and we will specify the exact mount and weight. The wrong surface match is the usual cause of instability, so this step is worth getting right before order.
