Concrete is strong in compression, but comparatively weak in tension. The inclusion of steel reinforcement improves the tensile strength of the element and, consequently, its resistance to stress. Unfortunately, in the presence of water and oxygen, steel corrodes. Therefore, in almost all likely exposure conditions for reinforced concrete, corrosion of the steel is a potential hazard.

Sika offers a complete range of high performance repair mortars and concrete for applications ranging from cosmetic to structural repairs. Our repair mortars and concrete systems are compatible with a full range of Sika repair and protection materials so that not only the visible signs of damage are repaired, but deterioration is addressed, extending the service life and sustainability of the structure.

Product Options for Concrete Repair & Protection

Steel Reinforcement Primers

Primer used as an anti-corrosion coating to reinforce steel in concrete restoration. Also, added protection to reinforcing steel in areas with thin concrete cover.

Bonding Agents

A wide-ranging line of epoxy adhesives and other bonding agents, which are natural, compounded or synthetic materials used to enhance the joining of a structure without employing mechanical fasteners.

Repair Mortar
Hand Applied Mortars

A workable paste material used to bind building blocks such as bricks, stones, and concrete masonry units together to fill and seal irregular gaps between them, which can be applied by hand.

Formed Repair Materials

An array of shutter formed repair materials used for the restoration of spalling concrete.

Machine Applied Repair Mortars

A workable paste material used to bind damaged concrete structures together to fill and seal irregular gaps between them. There are two types of application, which include wet-spray & dry spray processes.

Surface Applied Corrosion Inhibitors

Surface Applied Corrosion Inhibitors are easily applied to the surface of existing concrete to extend the service life of any reinforced concrete structure.


Protective Leveling Mortars/Surface Fillers

An extensive range of mortar repair material used for pre-leveling of surfaces to help restore the cosmetic or structural deteriorated concrete and mortar.

Protective Coatings

Protective Coating Systems used on a building front will protect against reinforcing steel corrosion, while still allowing the building to breathe with transmission of water vapor through the protective coating. These systems are made for multi-purpose use as well as for protective and aesthetical requirements.


Products applied to surfaces to reduce the penetration of water or chlorides. Sealers may penetrate into the surface or form a very thin surface layer.
