Geotechnical Days of the DGGT (German Geotechnical Association),
October 29-30, 2019
Formwork systems
Most parts in the ISCHEBECK formwork systems are made from aluminium. The low weight of the individual components improves safety, reduces fatigue and saves on crane capacities.
Whether a single prop or a complete falsework assembly, ISCHEBECK always supplies economic solutions ideally suited to the needs of building sites.
Geotechnical systems
with TITAN micropiles
One system – many applications
The heart of the system is the self-drilling TITAN micropile, which can be used as a ground improvement measure. Ground improvement by way of the interlocking body of grout enables tension, compression and cyclic loads to be transferred to the in situ soil. TITAN micropiles are covered by National Technical Approval Z-34.14-209 issued by the DIBt. This is the only tubular grouted pile system that can also be used for permanent applications of 100+ years.
Trench shoring systems
The ISCHEBECK trench shoring systems in steel and aluminium meet the requirements for fast progress on site, economic plant use and high safety. The modular system consisting of panels and trench struts ensures good flexibility and solutions to suit the needs of building sites.

FOundations and underpinning
with TITAN micropiles
TITAN micropiles transfer tension, compression and cyclic fluctuating and reversed loads to loadbearing soil strata according to DIN EN 14199.
- Little settlement
- Can also be installed with compact, lightweight plant
- Low-vibration method that does not damage existing buildings
- Ideal on confined sites
- Permanent solution for 100+ years
ANCHORAGES
with TITAN micropiles
The economic alternative to ground anchors
TITAN micropiles can carry tension loads without prestressing and are suitable for temporary and permanent applications (100+ years). Monitoring is unnecessary.
TITAN micropiles are installed to anchor sheet piling, retaining walls or excavation shoring, e.g. for
- flood defence walls, quayside structures and locks
- edge beams, historic masonry and gabion walls
- bearing pile, bored cast-in-place and diaphragm walls
SOIL NAILING
with TITAN micropiles
Self-drilling reinforcing element to DIN EN 14490
TITAN micropiles can be used as self-drilling reinforcing elements for nailing to DIN EN 14490. The hollow steel bars are installed with drilling and flushing fluid and subsequently grouted with a cement suspension in a dynamic process. These create a monolithic composite element together with the surrounding soil and thus function as a ground improvement measure.
The TITAN system ensures permanent corrosion protection and is approved for applications lasting 100+ years.
TUNNELLING & MINING
with TITAN micropiles
ONE SELF-DRILLING SYSTEM – MANY APPLICATIONS
The TITAN system is ideal for all kinds of temporary and permanent stabilisation solutions in tunnelling and mining projects.
- Drilling and installation is one operation
- Especially advantageous in rocks/soils with low cohesion and in unstable boreholes
- Borehole stabilisation with cement slurry (optional)
- Dynamic grouting during drilling (optional)
- Grouting assured over full depth of borehole
- No need to extract drill strings
ONE INSTALLATION METHOD
FOR ALL APPLICATIONS
FOR ALL APPLICATIONS
Irrespective of the ground conditions and the particular application, TITAN micropiles are always installed using the same method.
- Also suitable for changing soil conditions
- No separate casing
- No multi-stage grouting
- Installation according to approval Z-34.14-209
- 1 operation – 2 steps

FOUNDATIONS
LITTLE SETTLEMENT & SUITABLE FOR DYNAMIC LOADS
LITTLE SETTLEMENT & SUITABLE FOR DYNAMIC LOADS
Foundations to buildings, bridge piers and other structures where only minimal settlement is permitted.
Foundations to masts, noise barriers, etc.TITAN micropiles are suitable for fluctuating and reversed actions, even those with dynamic load cycle components.
UNDERPINNING
Installation with compact, lightweight plant
Installation with compact, lightweight plant
TITAN micropiles have been successfully used for strengthening foundations for decades:
- Building conversions
- Historic structures
- Electricity pylons
The system can be used flexibly: from foundations on inaccessible sites to underpinning in confined basement storeys.
PROTECTION AGAINST UPLIFT
DRILLING THROUGH SOIL & WATER
DRILLING THROUGH SOIL & WATER
Concrete ground slabs for sedimentation tanks, road underpasses, deep excavations, etc. in groundwater can be secured against uplift by TITAN micropiles. Using the ISCHEBECK bayonet system, it is possible to drill empty holes through water and soil.
- The piles can be installed prior to or after excavation = construction phases become independent
- The use of divers is reduced to a minimum
Seismic upgrades
Earthquake-resistant foundations with micropile groups
Earthquake-resistant foundations with micropile groups
The cyclic horizontal and vertical impacts and severe deformations that occur in seismic regions call for strong yet, at the same time, flexible foundations. Practical experience and empirical studies confirm that groups of piles consisting of several small-diameter grouted piles in a radial arrangement represent a more effective solution than piles with a relatively large mass, e.g. large-diameter bored piles, which concentrate the loads at a few rigid nodes. Groups of micropiles reduce the risk of soil liquefaction.
SPECIAL APPLICATION: THERMAL PILE
GEOTHERMAL APPLICATION
GEOTHERMAL APPLICATION
Pile foundations can be incorporated in geothermal installations. A TITAN micropile used as a thermal pile then has a dual function:
- Transferring loads to the subsoil
- Serving as a heat exchanger in a geothermal system
The piles often cover the basic energy needs.
