Environmentally friendly and economical: Functional patches allow rainwater to seep in


The choice of pavement in entrances, yards and terraces has a decisive influence on the level of wastewater costs. Functional paving helps save.

Non-percolating rainwater increases sewage charges

The sealing of floors by structures, traffic areas or paved areas on private land prevents rain from seeping into the ground. This endangers the groundwater level and thus the occurrence of drinking water. As sealed soil does not store precipitation, superficial runoff increases and canals absorb these amounts of water.

For this reason, most communities calculate split (split) sewage charges (GAG). They distinguish between dirty water and rainwater. The first is calculated according to the consumption of fresh water. Depending on the municipality, it costs between 1.50 and 2.30 euros per cubic meter.

Rainfall water is calculated by the municipalities according to the square meters of sealed area. They usually differentiate between full sealing (roofs, asphalt or concrete paths), which they charge 90 to 100 percent. Heavily sealed areas (pavement with open joints, composite blocks) flow in to 50 to 70 percent and less sealed areas (gravel, grass pavers) to 20 to 30 percent. The fee for rainwater is between 0.40 and 1.50 euros.

Whoever replaces 100 square meters of concrete with plaster ceilings with joints, pays only 20 - 105 euros instead of 36 - 150 euros. If infiltrated paving systems are used, these fees will drop to between € 8 and € 45.

Choosing the right plasters

Access to garages, carports and other parking spaces requires a stable covering that can withstand the weight of vehicles. There are less requirements for areas that only use pedestrians.

In both cases, sand and gravel paths are less suitable. The material is not stable and is pushed aside by the weight of vehicles. For pedestrians walking on such trails is uncomfortable.

The grass pavers known for decades are only partially a good solution. They have less stability than conventional plaster. Tires generate a loud rolling noise and walking on these stones is not pleasant. In wet weather, the soil in the grid holes is soft, there is a risk that narrow heels sink into it and take damage.

Better are so-called functional paving, which give the way stability and at the same time permeable to water. They offer the comfort of concreted or pebbled areas and allow rainwater to seep in well.

Since driveways, paths and squares need a base course, even gravel paths are never considered unsealed. So there is no advantage in having to dispense with stable but permeable patches.

Interesting facts about functional paving

At first glance, the stones do not differ from conventional paving stones or terrace paving. They ensure optimum infiltration through a combination system, without sacrificing stability or a smooth surface.

The water flows through cleverly shaped joints between the stones in the ground and through the stones. A special manufacturing process ensures that the stones are extremely permeable to water.

Important: The Research Association for Roads and Transportation (FGSV) has issued a "leaflet for leaking traffic areas" (M VV). The stones must fulfill the conditions of the leaflet and be tested according to DIN 18130. For the private sector is sufficient if the stones cope with normal resting and rolling traffic. Stones that handle heavy traffic are not required.

Cost and Benefit Analysis

Depending on the manufacturer, one square meter of bricks costs between 28 and 33 euros, whereas conventional bricks cost around 15 to 18 euros. When laying and laying, there are no differences. 100 square meters of functional paving costs about 1,500 euros more than conventional paving. You can save up to € 105 wastewater fees annually for this.

They offer more comfort than gravel or gravel roads or lawn pavers. In addition, the paving stones are significantly more durable than other permeable coverings. Their durability is comparable to that of conventional concrete blocks and is more than 50 years.

Considering the lifespan of the stones, a saving on wastewater charges of more than 5,000 euros is realistic.

As water becomes more and more precious, count on it Experts with rising sewage fees for sealed surfaces. Especially municipalities, which are currently charging low premiums, are sure to increase their prices.

Builders who build new buildings or plan to build new paved areas on the property in any case are well advised not to lose sight of the ecological aspect , In the long term, it pays to use functional paving stones. They are more permeable to water than conventional stones and more durable than the previously known alternative, the grass pavers.
