Broadbent Building, Heron Hall Academy


The Broadbent Building and adjacent gym block on the site of the former Middlesex University campus in Enfield, has undergone a major refurbishment as part of the new Heron Hall Academy project.

The art-deco facade is of a special interest and incorporates, now listed ceramic tiles. The building is constructed from brick with reinforced concrete floor slabs supported by reinforced concrete columns and beams.

Working as a specialist sub-contractor to Willmott Dixon Construction, following successful completion of other recent projects, we have been repairing and coating the external concrete elements which include the window cills, window heads and roof overhang, which project around the full perimeter of the buildings on all facades, as well as the entrance canopies.

The works have been carried out using Flexcrete materials and have included; Monolote hand-placed repair mortar for the repairs the the defective concrete and Monolevel 250F as a fairing coat, which has been specially formulated for application over existing coatings, being applied to all exposed concrete surfaces. To complete the system two coats of Monodex Smooth, a protective anti-carbonation coating primed with Bond-Prime, was applied. The system provided the client with 15 year guarantee.

Whilst on site we were also instructed to carry out internal concrete repairs using Flexcrete Monomix repair mortar, external brick stitching using Helifix Helibars and the installation of new expansion joints.

We are due to return to site in the new year to compete the second phase of the works.
