Definition and Fundamentals of Soil Exposures
Soil Exposures refer to the breaking up, opening, or uncovering of soil or rock layers to gain insights into their composition, structure, stratification, and in particular, soil- or property-related characteristics. In the legal context, the term is a collective designation for measures carried out within the scope of construction projects, geological investigations, raw material explorations, or waste law investigations. Soil exposures may take the form of drillings, excavations, shafts, or soundings. The primary objectives are often the exploration of the building ground, investigation of contaminated sites, or the preparation of construction and infrastructure projects.
Legal Basis of Soil Exposures
Statutory Regulations
The execution of soil exposures is governed by various laws and regulations. The most relevant are in particular the Building Code (BauGB), the Federal Soil Protection Act (BBodSchG), the Water Resources Act (WHG), the Nature Conservation Act (BNatSchG) as well as specific state regulations and provisions.
1. Soil Protection Law
The Federal Soil Protection Act (BBodSchG) contains provisions to protect the soil, in particular to prevent and assess harmful soil changes. According to § 3 BBodSchG, activities on soil, such as soil exposures, may only be carried out if soil functions are not sustainably impaired. Furthermore, investigations on suspected contaminated sites and potentially contaminated sites are legally mandated (§ 9 BBodSchG), with extensive requirements for planning, execution, and documentation of such measures.
2. Building Law
The Building Code (BauGB) stipulates that developers may or must initiate investigations of the building ground (site investigations) as part of the building permit process in connection with construction projects. Soil exposures prior to construction projects often require special permits or notifications, in particular for interventions in the natural environment (§ 14 BauGB).
3. Water and Nature Conservation Law
The Water Resources Act (WHG) provides for special licensing and notification requirements (e.g., §§ 8 ff. WHG) in cases of interventions in groundwater, as can occur during drilling. The Federal Nature Conservation Act (BNatSchG) also requires that interventions in nature and landscape, which often accompany soil exposures, must be minimized and—if unavoidable—compensated, for example through offsetting measures.
4. Geological State Law
The exploration of mineral resources and the geological survey of a state are governed by specific state laws, such as the Deposits Act or state soil protection acts. These often stipulate further notification, licensing, and documentation requirements, especially when soil exposures are connected to raw material exploration or scientific research.
Permits and Notification Procedures
Notification Requirement
In numerous cases, the performance of soil exposures is subject to notification to the competent authorities, in particular the local soil protection authorities, water authorities, or building supervision authorities. Notification must usually be given prior to commencing the measure and must include exact details about the scope, objective, location, and planned technical procedure of the soil exposure.
Permit Requirements
If significant interventions in the soil, groundwater, or the natural environment are to be expected from the soil exposure, an official permit is usually required. This can be granted as a license, authorization or as part of an Environmental Impact Assessment (EIA) under the UVPG. The concrete necessity depends on the type, scope, and location of the planned measure.
Special Regulations
- In the area of remediation of contaminated sites, action without official order may be subject to a fine.
- For matters relating to water law, such as the installation of groundwater monitoring wells, the Water Resources Act generally applies with its notification and permit obligations.
- Forestry work and soil exposures in forests are subject to forestry law and often additional state-specific regulations.
Duties and Responsibilities in Execution
Duties of Care
Operators are subject to comprehensive duties of care to prevent hazards to humans and the environment as well as harmful soil changes. These include, among others,
- the protection of groundwater,
- the proper separation and intermediate storage of soil material,
- the prevention of pollutant dispersion,
- compliance with technical and safety standards.
Documentation and Reporting Duties
Every measure of soil exposure must be documented. The documentation includes, among other things,
- type, scope and depth of exposures,
- sampling and investigation results,
- protective measures taken,
- if applicable, waste disposal.
These documents must be presented to the competent authority upon request.
Liability
Anyone who performs soil exposures is liable for any damage resulting from improper execution or insufficient safeguarding. This may result in civil liability (compensation, rectification) as well as public law consequences (regulatory order, fine, remediation order).
Reuse and Disposal Law
Soil material arising in the course of soil exposures can either be reused or, if contaminated, classified as waste. The relevant laws here include, among others, the Circular Economy Act (KrWG) as well as the Federal Soil Protection and Contaminated Sites Ordinance (BBodSchV).
Reuse is one of the primary objectives of waste law. Only when reuse is not possible or reasonable does disposal in compliance with waste regulations come into consideration. All transport, storage, and disposal require record keeping and, if necessary, official approval.
Practical Importance
From the perspective of construction, environmental, and infrastructure law, soil exposures are a central element of property and site development. They serve safety, the protection of people and the environment, and compliance with legal requirements in the planning and execution of technical projects.

Summary
Soil exposures are extensively regulated and associated with numerous legal obligations. From notification and approval to careful execution, proper documentation, and any reuse or disposal of the material, addressees of these regulations are required to observe a multitude of legal provisions to ensure environmental protection and legal compliance at all times.
Frequently Asked Questions
Who is legally responsible for approving a soil exposure?
Responsibility for the approval of a soil exposure in Germany depends on the respective state laws, federal mining law, and, depending on the purpose of the exposure, possibly on other specialist laws (e.g., nature protection law, Water Resources Act, soil protection law). In principle, approval for mining-related soil exposures falls under the scope of the Federal Mining Act (BBergG). In this case, the relevant mining authority of the federal state in which the exposure is to occur is responsible. For other purposes, such as geotechnical investigations, archaeological excavations, or other scientific surveys, other authorities may be competent, such as environmental agencies, building authorities, or lower monument protection authorities. It is therefore necessary to examine the specific project on a case-by-case basis and to consult the relevant legal regulations.
What legal requirements are associated with a soil exposure?
Soil exposures in Germany are subject to a variety of legal requirements. In addition to the general approval obligation, in particular, requirements for environmental, water, and soil protection must be observed. These include measures to prevent and minimize environmental damage, safety measures to prevent the spread of pollutants, and requirements for restoration after completion of work. Furthermore, there may be reporting and documentation obligations, for example, regarding found archaeological monuments or contaminated sites. In the event of interventions in nature and landscape, an intervention-impact assessment according to the Federal Nature Conservation Act (BNatSchG) is generally required, as well as corresponding compensation if necessary. Labor and occupational safety regulations—especially for work in contaminated areas—must also be observed.
What liability provisions apply in the event of damage caused by soil exposures?
Anyone who carries out a soil exposure is fundamentally liable for all damages caused to properties, goods, or the environment. This liability ranges from civil compensation claims of injured third parties (e.g., landowners, neighbors) to public law duties to avert danger, restore, or remedy damage. Under the Water Resources Act (§ 22 WHG), strict liability and remediation duties apply in cases of water pollution. In soil protection law, the rules of the Federal Soil Protection Act (§ 4 BBodSchG) regarding responsibility for harmful soil changes also apply. In the event of intentional or negligent damages, fines or criminal penalties may also apply.
To what extent are soil exposures subject to notification or reporting requirements?
Many soil exposures must be notified or reported, even if there is no explicit approval requirement. For example, the Federal Mining Act (BBergG) or the respective state soil protection laws require prior notification or communication to the competent authority in certain situations. This particularly applies to measures that may potentially affect contaminated sites, unexploded ordnance, or archaeological monuments. In addition, individual specialist laws require certain findings (e.g., pollutant discoveries, archaeological finds) to be reported immediately. Failure to provide notification can result in administrative or regulatory consequences.
What are the legal consequences of unauthorized soil exposures?
An unapproved or improperly notified soil exposure usually constitutes an administrative offense and can be penalized with fines or enforcement measures. In addition, the authority may order immediate cessation of work and restoration of the original condition. If the unauthorized exposure causes environmental damage, further measures such as remediation orders, cost notices, or claims for damages against the perpetrator may follow. In cases of gross negligence or intent, criminal prosecution, for example for environmental offenses, may also be pursued.
What special rules apply to soil exposures in protected areas?
Soil exposures within nature reserves, landscape protection areas, water protection areas, or FFH areas are subject to especially strict legal requirements. In these areas, not only are general nature protection permits required, but the specific provisions of the respective protected area regulation must also be observed, which often strictly prohibit soil-altering activities, deviations from which are allowed only in exceptional cases or with strict conditions. Often, an additional compatibility assessment (e.g., under § 34 BNatSchG) and the consent of other specialist authorities are required. Unauthorized interventions in protected areas can result in especially high fines and further administrative measures.
What role does property law play in soil exposures?
German property law generally provides that a soil exposure may only be carried out with the owner’s consent (§ 903 BGB). An exception applies only if there is a statutory right of use (e.g., in favor of public authorities for sovereign measures or on the basis of a statutory public law right of transfer or tolerance). Without the required consent or statutory authorization, any intervention constitutes a disturbance of possession or ownership, which can give rise to injunctive, restoration, and compensation claims by the owner. Even in public projects, a formal administrative procedure with compensation rules is generally required.
