The areas of delaminated concrete were broken out to behind reinforcement by the contractor. Large areas of breakout were repaired using Five Star Repair Concrete, a self compacting, flowable micro concrete. The smaller areas were repaired with weber.cem HB40 after first priming the reinforcement with weber.cem keycoat.
Deck repairs were undertaken with weber.cem pyrapatch, a fast setting repair material, allowing quick installation of the waterproofing membrane.
Following the successful completion of the repairs the surface of the abutments and wingwalls received applications of weber.tec guard MCI, a migrating corrosion inhibitor which protects the reinforcement against further corrosion.
In order to enhance the areas of low cover and to further protect against carbonation and chloride ingress, weber.cem fairing coat levelling mortar and weber.cote smooth anti-carbonation coating were applied to the repaired structural elements. The weber.cem concrete repair System holds an Agrément approved certificate.
