Make sure you are wearing appropriate safety protection throughout the entire process.
STEP 1: Excavation
Dig a trench.
Make sure the trench is deep enough to allow your edging block and 75mm of cement beneath the edging block.
STEP 2: Mixture
To secure your edging blocks use:
4 parts sharp sand to 1 part cement.
Step 1: Excavation
STEP 3: Laying
Use a taut string line to map out the line of your edging. Lay cement along this line before laying your blocks.
Use a paving mallet to hammer your edging blocks so that they are secure and at the right height for your driveway, patio or path.
Create a haunching on the outside of your edging block, to a minimum width of 75mm. This will hold your driveway, patio or pathway in place.
Step 2: Mixture
Edging blocks without sufficient haunchings will greatly increase the risk of damage occurring to the main driveway area. The haunching should come half way up the outside of the edging block. Smooth the haunching to provide a good aesthetic finish.
STEP 4: Curved Lines
Use a spirit level to measure back to the taut line to check the height of curved edges. Blocks may need to be cut to fit curved edgings.
To do this, lay out your edging first and use chalk to mark what shape on the block is needed.
Use a saw or block splitter to cut the blocks to shape.
Use the same method for laying from this point as you would on a curved edging.
Step 4: Curved Lines
The easiest way to create a curved edging is by creating an arc. To do this, find the central point on the proposed paved area and place a stake in the ground. Use a single length of string from this stake to measure out the location of each block to create a uniform and flowing curved edging.
STEP 5: Flat Top Path Edging
Flat top path edgings can be used to keep a paved area and garden soil or turf separate and to keep vegetation away from the path or patio. Flat top edgings come in three heights, 150mm, 200mm and 250mm. To haunch these edges, place on a bed of concrete 100-150mm and haunch three quarters of the way upside the ‘outside’ of the edging. The haunching will keep the edging pushed into the patio or pathway.
