Lay lawn edging stones correctly and place in concrete: lawn

Lawn edging stones can be set in sand or concrete. Also a laying directly into the soil is possible. However, if you want to prevent the stones from slipping over time, they are best placed on a concrete foundation. In the long term, this prevents a lowering of the stones. Do not worry, even for an active layman, this work can be done well. Below is the theoretical foundation, from the selection of suitable stones to mixing the right mixture.

Concrete, sand or earth

A stable laying of lawn edge stones in concrete is recommended
  • if there is a lot of room between the areas to be limited
  • when the soil is very loose
  • when lowering and other irregularities should be prevented over time
  • on slopes and when the boundary is also intended to protect against leaching
  • in especially large areas
  • When you are driving straight along a paved path or garage driveway

Stones, costs

For laying in concrete concrete or granite stones are best suited. Here everyone can choose according to his taste and budget. You have to expect for the running meter concrete blocks with costs of two to seven euros. It depends entirely on the quality and thickness of the stones. For granite stones you can spend 10 to 30 euros for one meter. The larger the purchase quantity, the better the price offer will be.

Selection, purchase

Before it goes to the selection, the course of the lawn edge must be clear. Should it just be a straight border on one side, should the corners of the borders be square or rounded? A beautiful harmony you get with a curved frame. This looks pretty, but can be problematic when mowing the lawn. It is also possible to sink the stones at ground level, then they are passable with the mower. As a rule, however, they close with the tip of the blades of grass. So, before the hardware store visit, determine the required number of meters and note the number of cornerstones and the curves. Small decision support:
  • Narrow stones are more likely not suitable for a high level difference between the adjacent sides. They lean slightly to the side.
  • For the delimitation to bed sections smaller stones look nicer.
  • For curved lines, suitable stones must be chosen for curves.
  • Large and robust stones are to be chosen if they are to lead along a driveway or a much used path.


As before the preparation of a lavish menu, it is also helpful when laying stones to first prepare all the "ingredients":
  • Edging stones
  • Power Cut
  • Sand, coarse and fine gravel
  • cement
  • water
  • spade
  • String, scissors
  • rubber hammer
  • trowel
  • Vat, bucket
  • Meter measure, spirit level


With a spade, first of all, along the edge of the lawn, one edge is tapped. If lawn edges are planned, then it makes sense to mark the course beforehand with a string. Along this edge you now lift a ditch. The size depends entirely on the stones. After completion of the work, the stones should look out about four to five cm from the ground. For the standard stone size, this will require a depth of about 70 cm, with a width of about 50 cm.

Meadow without lawn edge

This trench is filled with coarse gravel about 10 cm high. The gravel must be carefully compacted (started). For the next layer mix sand with fine gravel and distribute this mixture another 10 cm high, on the first layer of gravel. Now it is time to compact again carefully.


As a rule, lean concrete is used for the foundation of lawn curbs. Lean concrete is earth-moist and has a lower cement content than normal concrete. It is usually used for laying curbs. For this purpose, the required amount can be produced well yourself. Either in a concrete mixer or in a square mortar vat. The usual and sufficient mixing ratio consists of five parts of gravel (grain size 0.8 mm) to one part of cement. A quantity for water is not generally predictable. Very roughly, one starts from half a liter of water to one kilogram of cement.
First, the cement is mixed with the water to a kind of glue, then the addition (gravel, sand) is added. At the beginning, start with less water and finally add water if needed. How much water is needed exactly, can not be said so flat. It also depends on the outside temperature, the humidity and the humidity of the aggregate. With smaller concreting work, however, you are on the safe side with half a liter of water per kilo of cement.
Tip: The required amount of lean concrete, or cement, depends on the respective volume. So length times width times height. Delivery of the concrete is unlikely to be worthwhile for this type of project. Those who mix themselves is also independent in time.


The earth-moist concrete can now be applied to the compacted gravel layer. Not too much, so that the stones do not protrude too high in the end, they should stand about five centimeters above the turf. The concrete must be reassured thoroughly before the first stone is set. This must be carefully and ideally aligned with a spirit level. Now you can stretch a string again to be able to adjust all other stones in height.
Tip: During all concrete work, the area must be protected from heavy rain until the concrete has hardened. Otherwise, the cement components are rinsed out and the construction loses its stability.
The stones are placed on the concrete with a rubber hammer brought to the correct height. For this purpose, a spirit level performs well. If all the lawn edging stones are laid, they are given even more stability by using a trowel to brush some concrete sideways, right and left, as a wedge-shaped support. Finally, three quarters of the stones should be embedded in concrete. Now you let the concrete cure for a day. Once the concrete has hardened, the trench can be filled with soil again.
Tip: Between the stones should remain a small joint, which protects the stones from brittle spots on the edges.

The luxury variant

If you would like to have it quite comfortable while mowing the lawn, you can lay a series of flat paving stones next to the lawn edging stones. This keeps the lawn away from the curbs and can easily be used on a mower wheel. The trimming of the lawn curbs is eliminated.

Beautiful shapes

Turf lawn with lawn edges

In some gardens, a curved lawn edge fits better in the picture than a simple straight line. Grass edge stones, for example, have a rounding (convex, concave) on both sides. The cord as a guideline has of course then served. Here you can mark the lines for the excavation quite well with a garden hose. For larger projects, it is advisable to lay the stones with the desired curves in the grass. Do not be surprised, it will take a long time for the harmonious whole to emerge from the curved lines. Then you can pierce the stones with the spade right and left. After that, the stones are first put away and you can start with the excavation.


On a slope or on a steep slope, the grass cascades can be used in cascade form. Since the soil exerts a high pressure on the stones, setting in concrete is absolutely recommended.
That does not sound so difficult, does it? Anyone who chooses the sturdy variant with the cementing in of the grass edge stones is definitely on the safe side. If the stones are just to separate a flowerbed from the lawn, it is enough to brush some mortar or lean concrete right and left, wedge-shaped to the stones in the gravel.
