Available in a variety of textures, finishes, colour stains and sizes concrete garden borders offer an aesthetic appeal, are fairly simple to install and when fitted accurately will remain in place, durable and sturdy for many years to come.

For this simple Do It Yourself home improvement project you will need;

  • Water
  • Garden flags and Masons twine / string
  • Protective gloves
  • A dust mask
  • Protective clothing
  • Tamping tool
  • Small Spade
  • A Bucket
  • A trowel
  • Plastic sheeting
  • A circular saw
  • Pressure treated precast moulds or lumber to demarcate the area of installation
  • 30cm Stakes
  • Ready Mix Concrete and a pigment or stain if desired

Using stakes, garden flags and string, demarcate the area where you plan to place the concrete garden edging. Using a mason’s line, when curved lines are needed try and use the garden hose and drive stakes on the line once satisfied with the line/curve of the hosepipe. Excavate the area exposing a level and compacted trench to form the foundation for your DIY concrete garden edging. The dugout will need to be at least 20 centimetres wide and 10 centimetres deep to ensure a sturdy and durable installation.

Using precast moulds or lumber, install these guides along the sides of the prepared trench being very careful to place these in a precise position. The guides will steer the placement of the concrete that will form the outline of the concrete edging.

With the precast moulds or lumber guides in place spread the surface of the trench with a 2.5cm layer of river sand, patting it down as you go to prepare a compacted and level surface. 

Following the manufacturer’s instructions mix the cement with the recommended aggregate and add the desired pigment if necessary, be careful to follow the recommended water volumes closely, ensuring that the concrete mix is of the exact consistency but not too sloppy.

Pour the cement mix into the predefined precast moulds or lumber guides, smoothing this over evenly using your trowel. Be careful not to spill the concrete mix onto your skin or let it come in contact with your eyes, because of the caustic nature of cement/concrete of cement, when mixed with water the wet concrete mix can burn your skin and will need to be washed off immediately in order to avoid unnecessary injury a good barrier cream is recommended when working with cement and concrete products. 

Once poured and level, cover the uncured cement with plastic in order to protect it from scouring or drying out that will result in a low strength material, marks and unwanted imprints as it cures. The curing process can take up to 1 week so be sure to keep the area clear of pets and inquisitive little fingers looking to press a lasting impression into the pliable cement. 

Once fully cured, carefully remove the plastic covering as well as the precast moulds or lumber guides. Smooth out any undesirable rough edges, fill in the sides with garden soil and pat down to finish the installation.
