Concrete paving stones: Guide

Concrete paving stones are now widely used in the area of ​​driveways and gardens, they are relatively easy to lay, but can also form artistically sophisticated patterns. Concrete paving stones are characterized above all by a low price and a good ecological balance.

Where paved - and why

Paved paths not only provide a clean look in the driveway and garden, but they also form a smooth surface, which is easy to walk on and passable, but also better protected from contamination than just planed paths. On paved roads, there is less risk of accidents due to tripping than on non-paved undergrounds. Paving is therefore not only a visual remedy and a protection against the polluting influences of adverse weather, but also a means to increase the security around the house and garden.

Concrete paving versus granite paving

Granite paving stones are considered the hardest, toughest and most natural material for paving. Their disadvantage is above all the high weight, the significantly higher price and the lower selection of colors and patterns. In addition, granite paving is sometimes more difficult to lay than concrete paving stones.

The advantages of concrete paving stones are:

  • lower price
  • greater variety
  • lighter weight - this plays an important role in transport and deliveries, for example
  • much easier to lay

The only disadvantage is the lower durability compared to granite, but hardly anyone expects pavements to have durability categories of several hundred years, and even concrete pavement can withstand many decades without damage if it has been laid correctly.

Cost of concrete paving and granite paving

As with all building materials, the cost level upwards is always almost unlimited when it comes to special and exotic materials - but below are some guideline prices for better orientation:

Concrete paving stones in simple versions cost about 7 - 9 euros per square meter, some special offers or remainders are even lower. For the upper class you have to expect about double, about 16 - 18 euros per square meter. However, the upper limit for certain premium products is often 60 to 100 euros per square meter or even more.

For the price also other criteria play a role:

  • Shape of concrete paving stone
  • required quantity, larger quantities are often much cheaper
  • Presence of any remaining stock or special items

In comparison, granite paving stones are significantly more expensive: here, the target price is around 38 euros per tonne, that is, cheap stones, which are mostly from China, start at about 15 euros per square meter, good stone material from a closer production is often 80 Euro per square meter and often far more. Unlike concrete blocks, the granite paving stone also has other price criteria, namely

  • Hardness - measured on a scale of 1-10, with a value of 8 you already have one of the hardest natural stones that ever occur
  • Surface texture and
  • coloring

Of course, quantities also play a certain role here, but not as much as with concrete paving stones.

Life cycle assessment of concrete paving stones opposite granite paving stones

Although granite is a natural substance, the eco-balance is still significantly worse overall than with concrete paving stones, as granite is a plutonic rock that has to be extracted at great expense. Much of the cheap production comes from China, which means high transport routes and a correspondingly high CO2 emissions. Concrete, on the other hand, is usually produced locally, and the starting materials for concrete are natural materials, even if the building material itself is manufactured industrially. As a result, concrete paving stones are significantly more ecological than the granite natural product.

A look back

In the Middle Ages, only the streets of very important cities were paved, and often not continuously. The rest of the landscape had to be content with very simple cart paths, which were often deeply muddy in the rain and in the spring and barely navigable by carts. More advanced were the Romans: the Roman roads on dams, the course of which can still be seen today, were in Roman times something like paved "highways" that allowed a fast and safe passenger and especially goods and troop traffic and thus to The success of the Romans in Europe contributed significantly. Their construction was a monumental achievement.

Laying concrete paving stones

Armed with a rubber hammer, leveling plate and strings, the do-it-yourselfer can also dare to lay the concrete blocks. In any case, the laying of the subsoil has an important importance in laying, it is very important for the future load-bearing capacity of the concrete pavement.

The substrate preparation includes:

  • Paving the pavement area and removing about 15 - 20 cm soil
  • Laying the floor with a nonwoven, filling the floor with a thin layer of gravel to create a stable foundation
  • Fill with fine joint sand and carefully with the leveling plate, so that a flat laying reason ensteht

When laying yourself, you should proceed as follows:

  • The paving stones should be laid, curb stones first, at a distance of about 3 - 5 millimeters. Tap down with the rubber hammer and ensure exact horizontal alignment and the correct height, check with the spirit level more often.
  • After completion of the installation, apply fine joint sand until it solidifies and bonds the paving stones together.

laying patterns

Depending on your requirements concrete pavers can be laid both in the cross lattice and in the wicker fence, ornamental or strip grid, next mosaic pattern can also be laid, possibly with paving stones in different colors.

Prices for craftsmanship when paving

The cost of paving often differs depending on the operation - but also depending on paving area, local conditions and desired stones often from each other, on average, they move in a price range of around 50 - 100 euros per square meter including (cheaper) stones and without special laying patterns.
