What is a water-bound gravel

Water-bound ceiling - construction and manufacture

Anyone who buys a plot of land and designs it after the house has been built quickly ponders what is right as a covering for paths, parking spaces and parking spaces. Pavement is not only expensive but can also be a disadvantage in some areas, because a fee has to be paid per square meter of sealed area as the rainwater has to be taken up through a sewer system. Before making any considerations, you should definitely ask your municipality or city administration whether you have this tax or whether it is planned, because then you should try to keep the sealed (paved) areas as small as possible.

Water-bound blanket on a path

Water-bound ceiling / path surface

Many laypeople only know pavement as roadway or parking lot fastenings, these are available for every taste and budget, natural paving such as granite or basalt or concrete paving in all possible shapes and colors.

But there is also a completely different possibility, namely that water-bound blanket. Everyone has probably seen it before, because it is often used on low-traffic roads, for example in parks and forest paths.

But is the water-bound path surface also recommended for at home on your own property? Yes, it is, and it has a number of advantages. But there are also disadvantages, which you will find out in this article.

Info: Rainwater as a cost factor

More and more areas are being sealed, that means Rainwater seeps away not where it occurs but must be "disposed of" or discharged via a sewer system. The more surfaces are sealed, the more the sewer system is polluted and that causes extreme costs. For this reason, many municipalities and cities pass these costs on to those who cause them, i.e. to property owners who have sealed off areas on their property.

The amounts for this are different, we found out during research that you are between 0.40 and 1.30 euros per square meter lie. Anyone who has paved a large driveway including the courtyard will have to pay quite a lot annually for the sealed surfaces alone.

The advantages of a water-bound road surface:

The surfaces with a water-bound ceiling run, let rain seep away. That means: no levy has to be paid on these areas as rainwater can seep away on your own property.

Water-bound ceilings can of course be driven over, on your property with normal private use the path surface is suitable for every requirement, under the carport, on the parking space, on paths and even for the driveway.

Another advantage is that you can easily make the pavement yourself, assuming a little skill and a right and left hand, of course.

The disadvantages:

A water-bound blanket has to be withstood regularly. Because heavy rains can wear away the top layer. Snow plowing also clogs the road surface in winter, you can shovel snow, but this can damage the surface. In most cases, however, it is sufficient to sprinkle new pavement material. If you have your own plate compactor, you can use it to compact the new material.

Structure of a water-bound ceiling:

Construction of a water-bound ceiling

A base layer is placed on the compacted subsoil, which consists of 0/32 mm gravel. The base course is compacted 20 to 30 cm thick and well, depending on the subsequent stress. We recommend 30cm thickness for a stall / parking lot.

The leveling layer is placed on top of this base layer, which is made from 0/16 mm gravel and is 6 to 8 cm thick.

The actual road surface is then placed on the base layer, the material consists of 0/8 mm grain size. The pavement is available in some quarries and, of course, from building material dealers.

The top layer is damp, not wet, installed with a thickness of around 3 cm. When compressed, the top layer has a thickness of approx. 2 cm.

After the top layer has been applied, it is compacted. Ideally, this is done with a roller. However, it is also possible with a small vibrating plate (less than 100 kg). We have already achieved good results with it ourselves. If you have your own vibrating plate, use it when you put on your water-bound blanket.


Important: Of course, a path also has to be drained. You can do this by having a slope of 1 to 2% on one side. And you have to pay attention to this gradient from the beginning, it has to already exist in the base course. It is not possible to create the slope with the top layer alone.

Costs for a water-bound road surface

Often a reason why also for the water-bound ceiling What is decided is the cost. In comparison, the water-bound road surface is an inexpensive way of paving surfaces. This costs around 2/3 compared to paved surfaces. If you make the pavement yourself then it is of course a lot cheaper. The time saved compared to paving is also enormous.

Conclusion: The water-bound road surface is an ideal way to fix surfaces on your own property. However, (minimal) maintenance effort is to be expected, but this is limited on private property.
