Project History
This old mill’s original facade was to be repaired retaining all of its charm and aesthetic appeal. The five-storey structure had a conventionally reinforced concrete frame with masonry infill below the window openings. Over the years the concrete surface covering the steel reinforcing had carbonated allowing widespread atmospheric corrosion. Once the sandblasting of the masonry and concrete surfaces had been completed all surfaces to be repaired were treated with a single component water-based consolidant before placement of the repair mortar. Several application methods were used at that stage, on the 30 foot sills to a depth of 6 inches a form and pump technique was the method of choice. Smaller repairs used form and pour to avoid placement in lifts, shallow areas were trowel applied. After the repair mortar was placed, all surfaces were finished with a cement-based resurfacing mortar and two coats of breathable acrylic elastomeric coating.
