These Cantilever Concrete Parasol Base Slabs look stunning in every situation. Within the pack you will find 8 separate Concrete Slabs which should be placed in each corner of the Cantilever Parasol frame base. These slabs will help to secure your Cantilever Parasol in place & stop if from blowing over in strong winds. We recommend that you place as much weight as possible onto the Cantilever Parasol Base frame work, this will ensure your parasol does not blow over in strong winds. Ideally you will require 100kg to secure your Cantilever Parasol. Therefore we suggest that you place 8 paving slabs on the parasol base frame & lay the Concrete slabs on top of them. Another option is to purchase 2 sets of these Concrete Bases which will weigh a total of 100kg.
