Set a string line and level against existing surface to provide a straight line to follow set at the correct gradient Step 3 – Lay a Concrete Base in TrenchĪ couple of inches (50-75mm) of concrete mixed at 6 to 1, 6 parts aggregate to 1 part Portland cement (see our mixing concrete project) is laid along the line you would like the edgings to follow. This will give you roughly your 2 inches above ground level that the edgings will need to achieve in order to retain the driveway surface. Once your string line is tied in position between the 2 stakes, lay a spirit level flat on the existing surface the edgings are butting up to, in this case a pavement and adjust the string level down to the spirit level. To ensure that all of your edging stones are laid in a straight and level line you need something to follow, in this case a string line.īang a stake in the centre of the trench at each end and then run your string line between them making sure that it is runs between the centre of each stake. To provide the required base and support for any concrete edging stones you must first dig a trench to lay your edging stones in.įor this project we were going to use 6×2 inch round top garden edging stones so the trench itself needed to be around 6 inches deep and 8 inches wide and run the full length of the driveway area.Īs there will roughly be 2 inches of concrete in the base of the trench, this will allow roughly the top 2 inches of the edging stone to rise above ground level and contain the shingle for the driveway.Įnsure the base of the trench is nice and flat, smooth and level and free from any stones or similar objects.ĭig out trench for edging stones and ensure base is flat and smooth Step 2 – Lay and Level a String Line to Follow Step 1 – Excavate Trench to Lay Edging Stones in Regardless of which type is used the principle of installation is the same.Įdging stones are used to stop the base spreading as weight is applied to it and as such must be laid in a strong mix of concrete, or firmly embedded in soil if sinking straight into the ground.Ĭross section of concrete edging stones at the side of a pathway How to Lay Concrete Edging Stones Along a Driveway or Pathwayįor the purposes of this guide we are going to be laying some concrete edging stones around the front edge of a driveway to prevent the top coating of shingle from escaping. There are many types of edging stones for varying uses around the garden, some just sit in soil, some on a mortar bed and some need concreting in. This project deals with straight concrete edging stones or driveway edging stones as they are also known. Usually, one edge has a rounded "bull nosed" edge which softens the look of the stone and also protects car tyres when used on a driveway. Whereas kerbs are used for roads, edgings are used for driveways, paths and other hard surfaces. What is a Concrete Edging Stone?Ī concrete edging stone is a mini kerb. This project can be read in conjunction with our project on laying a gravel driveway or path. If you are laying any kind of driveway, path or hard surface, concrete edging stones or concrete edging blocks as they are also known are the go to solution to ensure the surfacing itself is contained and prevented from spreading and that any edges are protected from damage.
