This section is concerned with the use of BCR Compound SBR in patch repairs of reinforced concrete.

The information given here is suitable for small repair projects. BCR Compound SBR is also suitable for use on lager projects, but these should be considered individually by specialist concrete repair companies.

Advantages

Use of BCR Compound SBR in the concrete repair system gives the following advantages:

• Improved adhesion to background.
• Corrosion protection of steel
• Improved crack resistance
• Reduced thermal stresses because the coefficient of thermal expansion is similar to that of unmodified concrete.
• Protection of background concrete from carbonation
• Improved durability
• BCR Compound SBR has a long and successful track record of use in the construction industry.
