TITAN micropile

Global market leader, one system for many applications

The heart of the system is the self-drilling TITAN micropile that transfers loads to the subsoil. Micropiles can transfer tension, compression and cyclic loads and are used to secure structures.

ISCHEBECK can supply many different micropiles to suit different applications: anchorages, foundations, underpinning, slope stabilisation, tunnelling, mining, etc.

TITAN micropiles are approved according to National Technical Approval / Construction Technique Permit No. Z-34.14-209 issued by the Deutsches Institut für Bautechnik (DIBt) and are the only tubular grouted piles that can be used for permanent applications exceeding 100 years.

The following are just some of the convincing advantages of TITAN micropiles:

TITAN Micropile
An overview of the system

Our TITAN micropile system ensures maximum safety but at the same time maximum cost-effectiveness for your construction project. All components are available in many different sizes to suit the various loadbearing requirements. That guarantees efficiency and the flexibility to adapt to different ground conditions and applications.

One installation method
for all applications

Irrespective of the ground conditions and the particular application, TITAN micropiles are always installed using the same method.

  • Can also be used in changing soil conditions
  • No additional drilling tools required
  • No multi-stage grouting
  • Installed according to DIBt approval Z-34.14-209
  • One operation – two steps

Step 1
Direct drilling

  • A cement suspension is injected through the hollow steel bar and forced out through the flushing apertures in the drill bit.
  • The cement suspension functions as a flushing and drilling fluid to prevent the sides of the hole from collapsing.
  • The cement forms a mechanical interlock with the microstructure of the soil (filter cake).

Step 2
Dynamic grouting

  • The fluid of step 1 is displaced by a stiff cement suspension (w/c ratio = 0.4–0.5).
  • A grout body forms, creating a high shear bond with the soil.

Application areas
Geotechnical systems

Plant
on site

Various types of equipment can be used to install TITAN micropiles depending on the size of the TITAN hollow steel bar, the type of application and the restrictions on the building site.

Installation with hand-held hammer drill

For the smaller hollow steel bars, TITAN 30 to TITAN 40.

Installation with anchor drilling rig

Universal crawler track-mounted units for installing all TITAN hollow steel bars.

Installation with excavator-mounted drilling plant

For the smaller to moderately sized hollow steel bars and especially suitable for building sites with difficult access.

System
with approval

TITAN micropiles comply with DIN EN 14199 in conjunction with German Technical Specifications DIN SPEC 18539, which requires an approval.

Our product has been granted National Technical Approval / Construction Technique Permit No. Z-34.14-209 “TITAN system for use as a micropile” by the German Institute of Building Technology (DIBt).

This National Technical Approval / Construction Technique Permit regulates the design and installation of TITAN micropiles in Germany in conformity with construction law when used in the construction of permanent structures.

Grout body
section

Schnittbild Verpresskoerper Eng

TITAN self- drilling micropiles are continuously grouted, through dynamic injection, elements. The grout body therefore forms a mechanical interlock with the surrounding soil. The cement grout cover guarantees permanent corrosion protection and ensures that the loads are transferred to the subsoil. Any cracks in the grout body are limited < 0.1 mm (crack width limitation).
