Flomix – Mortars, Renders & Plasters


Contact us for sales or technical advice on this product



Roadstone Flomix is a range of dry-silo, factory produced, mortars, renders and plasters. Roadstone Flomix is ideal for construction projects which require an efficient and regular supply of quality mortars, renders and plasters to optimise the construction process, and maintain mix consistency throughout.

Roadstone Flomix is manufactured in our state-of-the-art plant, using traditional materials, to proven prescribed mixes which provide the optimum combination of strength, bond and workability. It is supplied as blended dry ingredients in silos and only requires the automated addition of water on-site. This ensures that mix quality and consistency is high and can be maintained throughout the build.
