Floating flooring installation method; floating floors are installed very differently from the methods above as they are not physically secured to the surface below, instead they are laid over an underlay and left to ‘float’. This method involves foam or rubber underlay that allows a softer feeling underfoot as the surface flexes.
As with the direct stick method, evenness of the concrete slab beneath is essential. If there is too much movement with a floating floor, damage such as cracking of click together fittings may occur or floors may squeak excessively. As such, concrete grinding or levelling may initially be required.
Floating floors are beneficial where people seek minimal time out of the property during installation as the product installed is usually prefinished (either engineered or laminate). The concrete slab may be treated with a moisture vapour barrier or the underlay may also act as the barrier (for certain brands).
With a good quality sound absorbing underlay, floating floors can also be effective in apartments and units. Installation of the flooring product is then simple, with boards laid in place and ‘clicked’ together or with adhesive applied at board joints (depending on brand and system). The skirting boards cover a necessary expansion gap at the edges and the floor is successfully floating.
