Various types of slow weathering processes can lead to a reduction of the given stabilities along the existing division surfaces and fault zones of rock slopes and banks that have existed for a lengthy period of time.
We assess the existing stabilities of rock banks with regard to potential dangers, such as rockfall, toppling or rockslides and plan suitable stabilisation concepts, including: 

• Geotechnical check measurements
  Anchoring
• Installation of wire netting
• Rock seals and underpinning

BFM can investigate the causes of damage to historic structures that can be traced back to geological and geotechnical factors of the subsoil or the foundation area (e.g. cracks or tilting) and develop appropriate rehabilitation and stabilisation concepts on the basis of the results.

BFM can investigate and assess the current stabilities of old near-surface underground mines by using technical aids such as drillings and camera inspections or, in favourable cases, inspections by geotechnical engineers. This involves measuring and mapping the opened cavities by geological engineers, estimating the risks and developing the required stabilisation and rehabilitation concepts.

When carrying out rock construction, the natural division surfaces and faults in the rock can act as mechanically effective weak points and have a great impact on the stability and serviceability of engineering structures in rocks.

In the area of rock and tunnel construction, BFM has a group of engineers and geologists who work closely together and compile, evaluate and interpret the relevant geological and rock-mechanical influence parameters, such as rock division surfaces and fault zones. BFM is thus equipped with the best qualifications for developing engineer services for investigating and planning, for proving that the required stabilities are present as well as for calling for tenders and supervising engineering structures in the rock during the implementation phase.

In the area of rock and tunnel construction, BFM can draw on many years of experience gained from national and international projects for public and private clients.

The range of projects that BFM has supervised successfully in the past stretches from simple rock foundations to stabilising slopes and banks alongside existing infrastructure projects right up to tunnel, cavern and pressure gallery projects and rock foundations in high-capacity power plant construction.
