SIKA

Sika offers a complete range of high performance repair mortars and concrete for applications ranging from cosmetic to structural repairs. Sika's 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. 

Sika Repair Mortars, Grouts & Concrete Application Guide 

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. 

1. TREAT ANY EXPOSED STEEL

Sika Armatec 110 EpoCem protects against corrosion and improves the bond of repair mortars.

  • Protects reinforcement in a high alkaline cementitious environment.
  • Can be applied on the damp surface obtained with SSD dampening.
  • Increases barrier to water and chlorides.
  • Fully compatible with load transfer requirements.
    Ensures homogeneous bond.

3. PROTECT FROM FUTURE OR LATENT DAMAGES

Sika FerroGard 903 is a corrosion inhibiting impregnation that penetrates and protects not only the repair area, but also the surrounding concrete from future corrosion due to latent damages.

  • Performance not dependent on chloride levels.
  • Active cathodic and anodic passivation.
  • Totally nitrite free (non-toxic).
  • Can penetrate to the reinforcement in one week.

2. REPAIR THE SPALLS

SikaTop Repair Mortars are easy-to-use one pack polymer modified mortars for replacing the concrete in spalled areas.

  • High build for security of application.
  • Easy to use, vertically or overhead.
  • Physical properties closely match parent building concrete.
  • Lower modulus for increased durability in high thermal movement (i.e., on building facade elevations).

4. LEVEL AND WATERPROOF THE SURFACE

Sika Leveling Mortars are protective leveling mortars which restore a
level profile to the concrete and effectively waterproof the
surface.

  • Fills bugholes and minor surface defects.
  • Provides an ideal substrate for protective coatings.
  • Application method controls consumption to needed volume only. 

5. PROTECT FROM CARBONATION

Sikagard Elastocolor is a protective, decorative and dynamically crack-bridging coating which protects the entire structure from the harmful effects of carbonation and water ingress.

  • Bridges dynamic moving cracks up to 12 mils (0.3 mm) at 16 mils (400 microns) dry film thickness.
  • Effectively halts carbonation.
  • Allows each way water vapor diffusion.
  • Prevents water and chloride ingress.
  • Enhances the appearance.
  • Gives excellent design opportunities with durable color.
