School Covered Walkway Column
Covered walkway column — Ryde, NSW.
Project Overview
THE PROBLEM
Spalling exposed corroded reinforcement on a concrete column supporting the school covered walkway.
THE REPAIR
Unsound concrete was removed, exposed steel treated and the damaged column section rebuilt with repair mortar.
THE OUTCOME
The column faces were reinstated and the exposed reinforcement enclosed within the repaired concrete profile.
SITE CONDITIONS
The walkway required clear work-area separation from school pedestrian routes.
Before & After
A Controlled Remedial Process
The repair sequence responds to the condition of the concrete, access constraints and surrounding site activity.
Inspection & Defect Mapping
Inspect the affected areas and establish the extent of concrete deterioration before planning access and repair zones.
Controlled Concrete Breakout
Remove unsound concrete back to a suitable substrate while protecting adjoining surfaces and the surrounding work area.
Reinforcement Treatment
Clean and assess exposed reinforcement, with any further steel repairs determined from its condition.
Structural Reinstatement
Place compatible repair mortar and reinstate the concrete profile to the specified repair detail.
Repair Finishing & Curing
Finish the repair faces and cure the material in accordance with the selected repair system.
Final Inspection
Check the repaired areas and remove work-zone protection when the repair and access requirements allow.
