When manufactured to the correct specification, reinforced concrete is an extremely durable construction material. However, most of us will be aware of so-called 'concrete cancer' and other forms of damage to concrete.

The most common causes of concrete damage are:

• Carbonation caused by CO2
• De-icing salts
• Insufficiant steel cover
• Poor concrete quality

The Vandex CRS Concrete Repair System provides a systematic procedure for concrete repair. The system consists primarily of cementitious materials which are homogeneous with concrete (strength, modulus of elasticity, thermal movement).

Vandex CRS Repair Mortar 05 is a versatile repair mortar with excellent workability. The cured mortar is highly compatible with concrete in respect of compressive and bending tensile strengths, modulus of elasticity, and coefficient of thermal expansion.

Vandex CRS Repair Mortar HB is a high-build repair mortar which is ideal for overhead application and/or when large areas need to be covered.

Vandex waterproofing slurries are cementitious powders that are mixed with water before being applied by trowel or spray. Once cured, they form an impermeable barrier that prevents the ingress of water. Vandex waterproofing slurries have a wide range of applications in the construction industry:

• Vandex Super is a "crystalline active" waterproofing slurry specifically designed for use on concrete.
• Vandex BB75 is the best-selling tanking slurry in the Vandex range and is widely used on cellar conversion projects.
• Vandex BB75E is an elasticized version of Vandex BB75 that benefits from enhanced flexibility and crack-bridging properties.
• Vandex Unimortar 1 is a waterproofing and repair mortar that can be applied in layers of 6mm - 12mm thickness
• Vandex Unimortar 1 is a versatile waterproofing and repairing mortar for horizontal and vertical concrete / masonry surfaces.
• Vandex Unimortar 2 is a cementitious, ready-mixed waterproofing and repairing mortar with hydrophobic properties. It is water and moisture resistant and is intended for use on horizontal surfaces.
• Vandex Plug. Water leaks and seepage are common problems in water-retaining structures and when building below ground, Fortunately, Vandex Plug offers a simple solution.
• Vandex CRS Concrete Repair System, Vandex CRS Repair Mortars 05 and HB are one-component cementitious repair mortars for concrete.
