In Tsakonas Building Supplies you will find the largest range of quality and branded, materials for retrofitting and structural strengthening of reinforced concrete structures. Solutions and materials adapted to the problem - pathology of each construction. The largest construction companies in Northern Greece trust us as suppliers in such a critical issue as retrofitting and structural strengthening.
Structural concrete reinforcement systems include a number of technologies, depending on the element of construction (column, beam, slab) and the type of loads (Vertical, Axial, Bending moments, Torsion) to be handled. It is the design that will determine the exact layout of the system to be implemented.
The use of a building or civil engineering structure may change throughout the course of its service life - for example, its function can change, loads can increase or higher building standards become required and the structure must be made compliant. Historical or landmark structures may need to be reinforced in a discrete way without impacting the original design or forms. To extend the longevity of the structure for many decades to come, structural strengthening is a safe, secure choice. Sika provides fully comprehensive, complete systems for all kinds of structural strengthening. Whether the requirement is to increase the bending, shear or seismic resistance, tested and proven Sika systems are available for use on reinforced concrete, steel, wood and masonry load-bearing structures.
SikaWrap®-230 C is a unidirectional woven carbon fiber fabric with mid-range strengths, designed for installation using the dry application process.
SikaWrap®-300 C is a unidirectional woven carbon fibre fabric with mid-range strengths, designed for installation using the dry or wet application process.
SikaWrap®-930 G is a unidirectional woven glass fibre fabric designed for installation using the wet application process.
● Carbon Fiber Reinforced Polymer (CFRP) Plates
Carbon Fiber Reinforced Polymer (CFRP) plates
Carbon-fiber reinforced polymer (CFRP) is used for reliable and high performance structural strengthening systems. CFRP based solutions consist of CFRP plates and rods, plus structural epoxy resin based adhesives. These systems are widely used for flexural strengthening of dynamically and statically loaded buildings and other structures such as bridges, beams, ceilings and walls, providing outstanding long-term durability in service.
Sika® CarboDur® M
Sika CarboDur M Type plates are pultruded carbon fibre reinforced polymer (CFRP) laminates designed for strengthening concrete, timber and masonry structures. They are bonded onto the structure as externally bonded reinforcement using Sikadur 30 structural adhesive.
Sika® CarboShear L
Sika® CarboShear L carbon fibre shear links are corrosion resistant, designed for strengthening concrete structures in shear and to anchor Sika® CarboDur® plates at their ends. They are part of the Sika® CarboDur® CFRP Strengthening System. Sika® CarboShear L shear links are bonded as external reinforcement using Sikadur®-30 epoxy resin based adhesive for normal, or Sikadur®-30 LP epoxy resin based adhesive for elevated temperatures during application. For fixing into the anchorage holes, Sika AnchorFix®-3+ can also be used.
Injection is a procedure of pumping cement-based, polyurethane-based, epoxy-based or acrylate-based material into damaged or cracked structures to securely seal leaks, repair compromised structures and make them watertight again for the long term.
Sikadur®-52 Injection Normal
Sikadur®-52 Injection Normal is a 2-part, epoxy, low viscosity, normal pot life, injection resin specially formulated for crack injection work by either pressure injection or gravity feed techniques.
Sikadur®-52 Injection LP
Sikadur®-52 Injection LP is a 2-part, epoxy, low viscosity, long pot life, injection resin specially formulated for crack injection work by either pressure injection or gravity feed techniques.
Sikadur®-53 is a 2-part, epoxy, moisture resistant crack injection and grouting resin.
● Strengthening of Masonry Wall
Strengthening of Masonry Wall
Textile reinforced mortar (TRM) is a composite material consisting of dry fibers embedded in a cementitious matrix, commonly used for strengthening masonry and concrete structures. In general, tensile characterization is required to identify the TRM mechanical properties, which are considered the key parameters needed for the structural design of strengthening systems.
What does the complex system of structural reinforcement of masonry offer?
Sika TRM inorganic matrix fiber mesh system
The Structural Masonry Reinforcement system is a flexible and easy approach to reinforcing load-bearing masonry against seismic actions. It consists of two main components, the Sika MonoTop®-722 Mur E mortar and the SikaWrap®-350 G Grid glass mesh and can be fastened with a SikaWrap® FX anchor, if required. It is used for:
● Connection between masonry panels & concrete frames ● Improving the ability to deform masonry in areas with strong seismic action ● Repair and filling of cracks in masonry
Sika MonoTop®-722 MUR E
Sika MonoTop®-722 MUR E is a ready to use, multi-purpose, 1 component, cementitious, fiber reinforced mortar for repairs with fiber mesh, pointing & rendering of masonries.
SikaRep®-200 Multi is a ready to use, multi-purpose, lightweight, cementitious, fiber reinforced mortar for repairs, pointing & rendering of masonries according to ΕΝ 998-1 and for non-structural concrete repairs according to EN 1504-3.
SikaWrap®-350 G Grid
SikaWrap®-350 G Grid is a bi-directional glass fibre grid, equipped with an alkali resistant coating, to be used as part of a textile reinforced mortar.
SikaWrap® FX-50 C
SikaWrap® FX-50 C is a unidirectional carbon fibre string, encased in a plastic envelope, that serves as fibre connector for the anchorage of SikaWrap® fabrics.
SikaWrap® FX-75 G
SikaWrap® FX Fibre Connectors are always installed in combination with SikaWrap® fabrics.
