Earth is excavated when building foundations, swimming pools or houses. This includes sand, clay and loamy substrates. Which disposal options come into question depends on the possible loads. In rare cases, further use is not possible.
Clay soil can often be passed on to interested parties
Fully recyclable clay floor
This material proves to be uncomplicated, because it can be used on your own property. Farmers in the area are often very interested in pure clay soils, so you can hand in the excavated earth free of charge.
If this is not possible, the substrate can be removed by a specialist company. In the excavated soil containers, you may only dispose of non-polluting soil that is free of branches, roots or plant materials such as reeds. Gravel and small stones are no problem. After cleaning, the material is used for flood protection or in the construction of landfills.
Limited recyclable clay
Special treatment plants filter toxic pollutants out of the soil. Since these processes are complex, there are different costs involved in disposal. The collection takes place using containers that you can rent for a certain period of time. With a trailer, small amounts of excavated material can be disposed of directly in a landfill. Storage and disposal costs are incurred here, which you should inquire about beforehand.
Orientation values for disposal:
- 180 to 250 euros per week if you fill the containers yourself
- 300 to 400 euros per week if a specialist company fills the containers
- 1,300 to 1,800 euros per truck load including all costs
Heavily contaminated substrate
In the worst case, the excavated clay soil is considered hazardous waste containing pollutants and impurities. Disposal takes place separately via containers that are designated for hazardous waste. The substrate must not be mixed with unpolluted soil. Waste wood, liquids or mineral excavated earth also do not belong in the same container. Whether further use is possible is decided after decontamination. The assessment of the pollutant load can only be carried out by a specialist company.
tips
The humic topsoil is considered worthy of protection because it contains valuable nutrients. This should not be disposed of in a container but reused or handed over.
