Laying a premix concrete path

Lay a concrete path quickly and easily with Easy Mix Concrete.

Easy Mix Concrete is a convenient, pre-blended, 25MPa concrete mix that is ideal for small DIY project slabs, paths, footings and garden edges.

Before You Start

Mark out the size of the area and calculate how many bags of Easy Mix Concrete are required.

  • 1x 10kg Bag = 0.005m³
  • 200x 10kg Bags = 1.0m³
  • 1x 20kg Bag = 0.01m³
  • 100x 20kg Bags = 1.0m³
  • 1x 30kg Bag = 0.0151m³
  • 67x 30kg Bags = 1.0m³

Note: Each 20kg bag contains approximately 10 litres of premix concrete.

What You Will Need


  • Shovel and rake
  • Spirit level
  • String line
  • Tape measure
  • Timber (for boxing)
  • Hammer, saw and nails
  • Screedboard and trowel/edging tool


  • Easy Mix Concrete
  • Potable (clean) water

Site Preparation

Dig the site to the required depth (most paths are at least 75mm deep). Allow space around the slab/path dimensions for the timber formwork. Use Easy Mix Double Washed River Sand as a bedding sand under the formwork if required.


Use lengths of timber to box the designated area. The top of the boxing will act as the level of the top of the concrete. Welded reinforcing mesh may also be added for extra strength. Ensure you allow for water run-off.

Prepare To Pour

Just before pouring your concrete, thoroughly moisten the area. This slows down moisture loss during curing and makes the concrete stronger.

Mix The Concrete

  1. Pour the required volume of premix concrete into a wheelbarrow or onto a clean surface. Use contents as soon as possible after opening the package.
  2. Calculate the amount of water you will need. As an approximate guide, use 1.0 – 1.2 litres of water per 10kg bag, 2.0 – 2.3 litres of water per 20kg bag and 3.0 – 3.5 litres per 30kg bag.
  3. Add water gradually and mix thoroughly to a stiff consistency. Do not add water after the concrete has been mixed, as this will reduce the final strength of the concrete.
  4. Shovel or pour the concrete into the formwork, then spread and tamp down with a shovel.

NoteExcess water can ruin good concrete, use caution when adding water to your mix.


Using a straight-edge board across the top of the formwork, ‘screed’ the concrete to the desired level. Work the screedboard across the top of the concrete, from one end to the other in a sawing motion to bring it to the desired level. Fill any holes and screed again, removing excess concrete if necessary. Leave the concrete to set for 30 – 45 minutes (depending on weather conditions) before proceeding.


For a non-slip finish (or if tiling over), use a wooden float in a circular motion across the slab. For a smooth, finish a steel float should be used. Edges should be finished with an edging tool for best results.


To help the concrete cure at full strength, cover with used damp hessian cloth and keep it moist for several days.
