Press Release Summary = With the new procedure for the early recognition of
building damage in the high and foundation engineering, announced by IBJ Technology
to the patent, show themselves damage in the solidium substantially in former times
as so far usually.



Press Release Body = Well-known procedures seize the geometrical changes (lowering
and/or deviation measurements) in the building, which already arose by effect of
strange influences. Change of the stress and redistributions of stress arise however
already before the geometrical changes. Ability these to be in time determined and
interpreted, can be reduced larger damage to the building by suitable measures or
turned away. The new and world-wide only procedure for the early recognition of
building damage by the long-term observation and the comparison of stress
measurements within the buildings by means of ultrasonic, is based on the
akusto-flexible effect. The running time of an ultrasonic impulse within
inhomogenously buildings is measured in homogeneous and isotropic measuring bodies.
The speed of sound of the ultrasonic waves depends on the flexible stresses within
the measuring bodies. If one uses a flexible not compressable medium, for example a
solid body well-known composition, as measuring medium one can by the determination
of the change of speed of sound, which tensions in the surrounding building
determine. A condition for this measurement is form and actuated conclusion of the
measuring bodies with the building. The connection of the measuring bodies knows
positive connections by special cement, or for example by embedding in construction
units with elastomers, by force and, how take place with supports from construction
units or counter bearings from bridges. A highly soluble measuring technique signals
changes in the stress structure immediately over a bus system. The new procedure can
be begun favourably for the increased safety of underground buildings, so in the
tunnel and build from caverns. The mountain stress in-situ are measured. The
measuring bodies can be brought in also radially between the tunnel lining and the
mountains. In connection with building information systems for buildings of all
kinds it can contribute substantially to building security. More preferentially the
installation takes place in foundations, columns or supports.
