Refurbishing decaying concrete facades

Concrete structures often show signs of degradation over a period of time and these detract from the appearance and can eventually affect the structure.


1. Corroded rebar affects concrete cover

Over a period of time, carbonation will affect concrete cover to reinforcing steel and lead to its corrosion. Unattended this will in time make the structure unsafe and eventually uninhabitable.

This effect is especially associated with construction where there is insufficient concrete cover to reinforcing steel.

2. Inadequate patch repairs

Simple cutting out and repair of decayed areas can leave uneven surfaces and even after fairing coats are used buildings retain their original, often dated, appearance.

3. Failure to prevent further corrosion

Even when repaired, the process of deterioration will continue in other areas if no action is taken to protect the structure from the elements.

4. Low thermal insulation

Old structures that have degraded over time often have low levels of thermal insulation when compared to modern standards and are more likely to suffer from related condensation and damp problems.
