REMEDIAL
We have many techniques available to extend the life of ageing
structures: strengthening through composite materials including
carbon fibre fabric
(TFC),
shotcrete
and
additional
prestressing; refurbishment through
concrete and façade
repair, sealing,
cathodic protection
and realkalisation. The application of high-performance
maintenance extends the durability of structures.
Cathodic Protection and Realkalisation Systems
Austress Freyssinet can provide cathodic protection, cathodic
prevention, realkalisation (Regebeton™) and electrochemical remediation
systems for a range of structures including reinforced and
post-tensioned concrete structures, bridges, wharves, jetties and buried
pipelines.
We can design, supply, install, commission and maintain the system,
including additional remediation works such as hydrodemolition,
shotcreting, and concrete repairs to complete the project.
Carbon Fibre Strengthening - TFC® & LFC®
The TFC® (carbon fibre fabric) and LFC® (carbon fibre laminate)
processes are patented systems for structural strengthening by the
bonding of carbon fibre based fabrics and laminates.
Its applications include
bridges and industrial structures made from concrete, steel, timber and
masonry. The carbon fibre materials are light yet a versatile
strengthening solution as it is insensitive to corrosion, UV’s
freeze-thaw and immersion and comes in various widths.
Additional Prestressing
Additional prestressing consists of adding external forces to modify the
stress condition of on existing structure so that it can be restored to
its original working capacity or even increase its load bearing
capacity.
Structures where this technique can be used include bridges; circular
structures such as water towers and silo; and building slabs and beams.
Additional prestressing can be performed using the Freyssinet Strand
Post-tensioning or the Freyssibar system..
Facade
Repairs & Renovations
Austress Freyssinet can provide a complete solution for the repair of
building façades built in a variety of materials with the most common
being reinforced concrete and masonry
Shotcrete and Gunite
Shotcreting (wet process)
and Guniting (dry process) are widely used techniques of placing
concrete by spray through a hose using compressed air. It is mainly
used for the repair and strengthening of structures.
The advantages of this technique are:
· Fast and flexible operation
· Perfect bond on prepared surfaces
· Adjustable application
· Low shrinkage
Access and Temporary Work Platforms
Austress Freyssinet can, as part of its overall remedial contract,
design and supply a range of access systems
and temporary works structures for both buildings and major civil
engineering structures
