When a housing association in West Yorkshire needed help and advice on concrete repair Structuralwise were asked to provide a guaranteed solution where other concrete repairs had failed to repair damaged concrete in the past.  Damage had occurred as a result of water ingress through cracks and pores in the concrete resulting in some corrosion of reinforcement bars. This corrosion had eventually caused the reinforcement bars to expand resulting in the removing of the face of the concrete, otherwise known as “spalling”.

The Structuralwise solution to the concrete repair utilised our 2 part concrete repair system. This system comprises of a light weight polymer  modified mortar and a one component finishing mortar.

The images below show the damaged concrete prior to the concrete repair and the exposed reinforcement bar that has been grit blasted and is now ready for stage 2 of the concrete repair process.

Below we can see in close up the exposed reinforcement bar following grit blasting. The grit blasting is necessary as it removes any oxidation prior to the concrete repair taking place.  The concrete repair medium is then hand applied in layers to build up a strong concrete repair.
