Carbon Fiber Plates for Structural Strengthening
Sika® CarboDur® S is a carbon fiber-reinforced polymer (CFRP) plate designed for the structural strengthening of concrete, timber, masonry, and steel structures.
Sika® CarboDur® S plates are bonded to the structure to provide external reinforcement. This is achieved using the epoxy resin adhesive Sikadur®-30 for standard applications, or Sikadur®-30 LP for use in environments with higher temperatures.
Please refer to the relevant product data sheets for further information regarding each specific adhesive.
SikaCrete® Gunit-103 is a single-component cementitious repair mortar designed for concrete repair using the dry-mix shotcrete method. It contains microsilica and flow-enhancing agents, which ensure a dense, well-bonded matrix and rapid strength development—all without the need for setting accelerators. It is ideal for large-scale structural concrete repairs, tunnel projects, underside concrete repairs, and hard-to-reach areas. The product can be applied in layers up to 150 mm thick, while minimizing rebound and material waste, thereby enhancing on-site operational efficiency.
Sika Crete® Micro SCC UW is a pre-packaged, self-compacting micro-concrete designed for the structural repair of concrete elements underwater. It features excellent flowability, low heat generation, and resistance to cement washout during underwater placement. It is ideal for repairing bridge columns, piers, piles, dams, and large reinforced concrete structures—particularly for applications utilizing the tremie concrete placement method. The product offers high strength, ease of use, and consistent material quality.
Hydrophobic Polyurethane Foam for Crack Injection
Sika® Injection-127 H is a hydrophobic polyurethane injection sealant designed to stop water leaks.
It is a special, ready-mixed, one-component cement. Contains a mixture of modified polymers, silica fume, and rust inhibitors. Used for cementing concrete and preventing rust of reinforced steel. in concrete repair work
Thixotropic epoxy adhesive for structural strengthening applications
Sikadur®-30 is a two-component, thixotropic structural adhesive based on a combination of epoxy resins and special additives. It is suitable for use at temperatures between +8 °C and +35 °C.
Sikadur®-30 offers the following benefits:
Epoxy resin for the saturation of reinforcing fibers
Sikadur-330 is a two-component, thixotropic epoxy resin used for the saturation of reinforcing fibers.
Two-Component Epoxy Injection Resin
Sikadur®-52 TH is a two-component, low-viscosity, solvent-free epoxy injection resin that develops high compressive strength. Once the two components are mixed, the material can be injected into voids or cracks within concrete; upon curing, it forms a rigid, high-strength material.
Sikadur®-52 TH is a liquid characterized by excellent penetration capabilities and high bond strength. Additional benefits include the following:
This is a three-component coating material consisting of Portland cement, epoxy resin, selected aggregates, additives, and a corrosion inhibitor. It serves both as a bonding agent between existing concrete and new repair materials, and as a protective coating against the corrosion of steel reinforcement. The product complies with the specified requirements.
