BALCONY REHABILITATION (Concrete)

1. Chip out loose and/or delaminated concrete at fascia-edge locations. Where rebar has been exposed and/or shows rust or corrosion, chip back concrete one inch so as to expose the rebar in full and remove concrete down to a solid substrate.

2. Sound out soffit and deck surfaces with the use of a ballpeen hammer or chain to locate delaminations or spalls. Report on quantities to owner or his representative and location of the deficiencies found.

3. Where the balustrade or railing base plates are corroded and/or concrete has spalled, remove unsound concrete and cut perimeter a minimum of one-half inch to prevent the repair from "lifting" or de-bonding.

4. Remove any rust with the use of a wire brush or wire wheel (or other method, dependent on scope of work) and coat metal with a zinc-rich paint or epoxy coating.

5. All thru-slab repairs shall be formed and the exposed concrete slurried with a cementitious base prior to placement of new concrete material.

6. Soffit/deck (and base-plate) delaminations shall be repaired with an acrylic-modified repair material (where such exhibit a depth of less than an inch) and brought to their original planes of the surrounding surfaces.

7. Form-work shall be left in place in accordance to the manufacturer's instructions for the product used. Any drip edges interrupted in carrying out repairs shall be re-installed prior to leaving the area and the work made good.

8. Where requested (and listed in the scope of work), the deck and fascia shall be flood-coated with a water repellent material to retard future water permeation of the slab surface.

NOTE: It is highly recommended that a waterproofing membrane be installed to the deck and fascias of balconies, once repairs have been carried out. A minimum preventative measure or alternate would be the application of a concrete sealer to these surfaces to disallow the permeation of water entry into the slab surface.
