The corrosion of steel reinforcement in concrete is the single biggest cause of infrastructure deterioration. This is caused by two factors: carbonation, leading to loss of concrete alkalinity and chloride attack from de-icing agents or seawater which break down the protective oxide film of the steel.
Moisture and oxygen can cause expansive corrosion up to eight times greater than the original steel, which can lead to concrete cracking, delamination, and spalling.
We are approved applicators of the leading manufacturers’ repair materials. Our highly trained personnel have repaired structures including bridges, high rises, dams and weirs. Operations include defective concrete removal, surface preparation, levelling, spray applications, mortar works, crack-bridging, anti-carbonation coatings, carbon fibre plate reinforcement and crack stitching with Helifix solutions.
The material we provide is suitable for a ride range of building and repair needs, especially where excellent bonding, high strength and abrasion resistance is needed – in permanent repairs to spalled or damaged concrete, for example.
