Foundations and underpinning
with micropiles

The primary characteristics of TITAN micropiles include their exceptional load-bearing capacities and minimal susceptibility to deformation. These micropiles are suitable as deep foundations for a wide range of structures, encompassing various building types, bridges, masts, pylons, and other intricate constructions.

When arranged in groups, micropile foundations efficiently transmit forces to the underlying soil. Notably, for dynamic cyclic loads, groups of such micropiles have demonstrated significantly more efficient when compared to foundations that rely on large-diameter bored piles.

TITAN micropiles

  • are an approved system for temporary and permanent applications,
  • can be used on confined jobsites and where access is difficult,
  • are installed using small, lightweight equipment with low-vibration and gentle operations.

Building foundations

When it comes to new foundations for buildings and structures, TITAN micropiles represent an efficient, dependable alternative to traditional piling systems. Our micropile system is covered by European standards and approved for permanent applications. Self-drilling TITAN micropiles can be used in all types of soil and combined with other foundation forms, e.g. raft foundations. The system offers a series of advantages for designers, contractors and clients:

Advantages for Designers

  • System with National Technical Approval
  • Flexible application options in difficult boundary conditions
  • Low-settlement system
  • Suitable for all soil types

Advantages for Contractors

Underpinning existing structures

TITAN micropiles are installed using compact, lightweight, and flexible drilling equipment. Especially when refurbishing and upgrading historical structures, it is advisable to choose a system that generates minimal vibrations to prevent potential damage to the existing structure. TITAN micropiles are commonly utilized not only to reinforce strip footings, raft foundations, and piled foundations but also to mitigate ongoing settlement issues.

Industrial structures and factory buildings frequently require modernization or retrofitting measures, particularly involving upgrades to their foundations to support production facilities. Challenges include working within confined spaces and adhering to tight timetables to minimize disruption to production operations. Additionally, there is the task of effectively transferring dynamic, fluctuating, and reversed machinery loads to the subsoil.

Mast & Pylon foundations

Tensile, compressive, and shear forces, as well as bending and torsion moments frequently act concurrently on tower-like structures such as electricity pylons, telecommunications masts, wind turbines, and ski-lift masts. Small clusters of TITAN micropiles arranged radially can effectively handle these loads and transmit them to the subsoil through skin friction.

Masts and pylons are frequently erected in remote and challenging environments. The TITAN micropile system allows for rapid installation using compact, mobile equipment, eliminating the need for complex logistics. In urban settings with numerous underground utilities, this system offers a space-efficient alternative to bored piles or gravity foundations. The screw-on pile head details facilitate straightforward connections to steel or reinforced concrete superstructures.

Bridges

TITAN micropile groups are ideal for bridge foundations requiring minimal settlement. These micropile groups settle significantly less compared to large-diameter bored piles. They can be installed at various angles, aligning with the force directions in arch bridge designs. This alignment significantly reduces unnecessary shear forces and moments, leading to more efficient bridge foundations.

Foundations to bridge piers – the advantages in detail

  • Better settlement behaviour (pile groups)
  • Requires smaller drilling equipment compared to large-diameter bored piles
  • Less complex planning and logistics
  • Reinforcement cages are not required
  • Less concrete

Protection against uplift

When constructing concrete ground slabs for sedimentation tanks, road underpasses, deep excavations, and similar structures in areas with pressurized groundwater, TITAN micropiles offer a reliable solution for preventing uplift. The ISCHEBECK bayonet system allows for the drilling through both water and soil. Once in place, this system establishes a structural connection. Uplift-resistant piles can be drilled through soil or water before or after excavation, thereby separating construction phases and minimizing the need for divers.

During the construction phase, TITAN micropiles prevent the uplift of underwater concrete slabs. Later, they serve as permanent foundation piles for the completed structure.

The TITAN system can also be installed in areas with groundwater under hydrostatic pressure conditions.
