CEMIX MULTICRETE is ideal for all types of general purpose concrete work. It consists of a uniformly blended and proportioned mixture of sands, aggregates, Portland cement and admixtures, designed to improve the concretes workability and performance. CEMIX MULTICRETE is grey in appearance however it can be coloured to suit using selected CEMIX OXIDE POWDERS. It can be further enhanced by using the range of CEMIX decorative sealers and dust proofing hardeners. When mixed to the instructions below, CEMIX MULTICRETE will attain a minimum compressive strength of 28MPa after 28 days.


  • Concrete jobs with a minimum of 40mm thickness
  • Slabs and patios
  • Foundations and footings
  • Footpaths
  • Mowing strips
  • Driveways


CEMIX MULTICRETE is designed for every day general purpose and structural concrete work. It is a structural strength product, however for all high strength commercial and civil applications please use CEMIX MAXCRETE 45MPa.


  • The area to be concreted should first be marked out with string lines
  • Once excavated, ensure the area is firm. A layer of compacted gravel and/or reinforcing steel can be used if required
  • Place 20mm thick wooden boxing edge timber and secure with wooden pegs at 600mm – 900mm intervals
  • Dampen the area before the concrete is placed


  • If only a portion of the bag is being used, the entire contents must first be emptied in to a wheelbarrow and gently yet thoroughly reintegrated, as the materials may have segregated during transport
  • One bag of CEMIX MULTICRETE will require approximately 2.5 litres of clean fresh water
  • In a clean wheelbarrow or mechanical mixer add approximately half of the prescribed water
  • Next, add the contents of the bag and mix thoroughly for 2 minutes
  • Add more water up to the maximum of 2.5 litres in total and continue to mix for an additional 3 – 4 minutes until a suitable mixture is achieved. The ideal mix should resemble porridge. Do not add more water as this may weaken the finished set concrete
  • Use mixed concrete immediately. Do not allow to stand
  • If no wheelbarrow or mixer is available, CEMIX MULTICRETE can be mixed on a clean flat surface by placing the dry material first, then adding the water and mixing as above


  • Place the concrete into the boxed area, spreading it evenly with a spade or rake, ensuring that the concrete reaches all corners. Care must be taken to thoroughly work the mix as you go, to remove any air voids. This can be achieved with sharp stabbing motions with the spade. Alternatively, a mechanical concrete vibrating device can be used
  • Once the concrete is in place, gently tap the boxing several times every 1 – 2 metres to remove any air voids that may have accumulated at the edges
  • Level off the concrete and finish flat with a wooden straight edge
  • Final finishing can be done after approximately an hour, once the concrete has partially set and any initial surface water has
