Hot tubs can provide one of the biggest base-building challenges due to the exposure of the base to many destructive influences such as chlorinated water, frost damage, UV radiation, standing water and of course, heavy loads. As the weight of a large hot tub when filled can be as much as 2.5 tonnes, these destructive influences can, over time, cause the base of the hot tub to fail. The failure of a hot tub base can result in damage to the spa itself, with repairs running into hundreds of pounds.

Traditional bases tend to be constructed from either concrete slabs as per a patio, or from timber in the form of decking. Both of these choices are now old-hat methods of creating a solid base for a hot tub as plastic technology has improved massively over the past decade. As X-Grid is a permeable paving grid, when filled will still allow water to pass through the surface and eliminates puddling often seen with concrete alternatives. With the high likelihood of large amounts of water being deposited around the base of the tub, this is an important issue to deal with to prevent slips and hot tub base degradation.

Manufactured from an inert 100% recycled plastic, X-Grid is immune to the effects of chlorine which means that unlike timber, it will not break down over time and does not require annual painting or sealing. With a loading capacity of 420 tonnes per square metre when unfilled, X-Grid is perfectly capable of coping with the intense weights of a filled hot tub. The modular design of X-Grid allows for asymmetric shapes to be created, making it perfect for hot tubs and swim spas, regardless of their shape or size.
