Cemintel Constructafloor® Internal flooring is a high strength, durable fibre cement structural flooring product. It can be fixed directly to structural framing to form the interior substrate for both wet area and non-wet area applications.
The substrate is resistant to water when paired with a suitable waterproof membrane system, offering a waterproof flooring solution for wet areas such as bathrooms, ensuites and laundries. It can then be covered with your selection of tiles or decorative finishes.
In non-wet areas applications, Constructafloor Internal flooring may be finished with carpet, direct fixed tiles or vinyl sheet in areas that are not required to be waterproof. Constructafloor Internal offers proven, reliable and cost-effective solutions to all internal residential wet areas and other tiled areas.
