Concrete
A poured slab of concrete or concrete patio are required to place your Swim Spa on. We advise the following steps as a minimum concrete base for your Swim Spa:
Excavate a 20-30cm/8-12inch deep area for your concrete base and use a Wacker plate to compact the area down
Lay 20-25cm/8-10inches of MOT type 1 sub-base gravel to fill the area and repeat Wacker plating to compact this again
Lay a minimum of 15cm/6inches of concrete to fill the area
The concrete support slab must be flat and level in order to properly level the Swim Spa during installation. The concrete pad should be slightly larger than the dimensions of the Swim Spa, but may be expanded further if required. Ensure that your concrete base is capable of supporting 1,500kg/m² (250lbs/ft²).
