Heritage restoration currently under way.

HSR were engaged by Renewal SA to carry out a full dilapidation and associated costs to the East/South and Western facades of the Adelaide Railway station in order to determine a scope of works for the repair of structural and non-structural rendered elements that form the facades of the Railway Station.

Prior to the works being carried out the façade was cleaned by HSR using a steam pressure cleaner which provides a super-heated steam rather than the usual high-water pressure, this machine removes all dirt /grime etc. without the risk of excessive water penetration into the open cracks etc.

Various repair methods were used on the project as outlined below:

  • Full render repair – Removal of a defective area and replace with new render that matches exactly with the original in both colour and texture.
  • Crack injection- small cracks are filled with a coloured mortar to match existing, then a two-part epoxy resin is carefully injected into the crack using small syringes.
  • Structural repairs- in the case of steel corrosion behind the render, the render is removed to expose the underlying steel reinforcing which is then cleaned to remove loose corrosion, once cleaned the steel is treated with a zinc rich protective coating, then treated the area is re rendered to match the existing.
  • Protective membrane application – a protective coating was applied to all horizontal surfaces Window sills /cornice sections etc. in order to provide a stable waterproof finish.
  • Entire replacement of moulded sections under the cornice – In some cases continuous water penetration had caused severe corrosion of the Modillions which form a decorative part on the underside of the cornice, due to their friable nature these sections had to be removed entirely and new pieces carved by HSR masons and fixed into place.

HSR were engaged by the main contractor Complete Building Services to carry out a full dismantle and rebuild of the entire Northern elevation of the Maid and Magpie Hotel in order to rectify the damage created by the subsidence within the original footings.

Full dilapidation was carried out by HSR prior to commencement of the project which included a comprehensive photographic record and exact dimensions of each element of the area, this included locations of windows, chimneys and any other feature that needed to be re-instated during the rebuilding process.

Starting at the roof line of the elevation the entire North wall was carefully dismantled brick by brick and stone by stone with each individual item being documented and cleaned for re use.

Over a period of several weeks the process continued until the entire wall was taken down and catalogued by a team of HSR masons, with all bricks and stone carefully palletised according to its location thus ensuring the materials were re laid in their original position.

Once a new concrete footing was installed HSR began the process of rebuilding the elevation using all the previously salvaged original materials and utilising the details taken during the dismantling process.

Consultation with the project Architect and Heritage advisor ensured that the rebuilding process produced an exact re instatement of the original Northern Elevation in every detail.

 

Extensive works reinstating all damaged heritage brickwork, ornate solid rendering to external facades including all internal rendering and plastering, and making good cornices and mouldings.

New and refurbished metal windows and guarding, and specialist cleaning to all masonry facades.

 

The project included the conservation and restoration works to the exterior and interior of the telecommunications exchange building.

The scope of works involved specialist façade cleaning, heritage brick work, stone and timber conservation and solid rendering.

HSR undertook Stonework Repairs, Replacement along with Façade Cleaning, Repointing and mortar repairs. HSR scoped the works alongside the Client, provided cost planning in the early stage prior to works commencing. Window repair and repainting of the steel windows was done alongside the Façade works.

The Bank of South Australia building, done in an ornate French renaissance style, was erected between 1875 – 1878. The building has many exceptional features, which were originally undertaken by celebrated Scottish sculptor William Maxwell and British painter and sculptor Joseph Durham, in particular the intricate stone carvings and the coat of arms on top of the portico on the King William street façade.

This project involved structural concrete repairs and stone replacement to abutment features, safe removal of chrysotile asbestos mason’s putty to stone ashlar joints, specialist façade cleaning, solid render repairs and crack stitching and injection. HSR also sourced the original stone and re-opened Waikerie Limestone Quarry purchasing the mining lease.

The Mackillop Centre former St Vincent de Paul Orphanage in South Melbourne, is of architectural significance as an imposing, Italianate mid-nineteenth century institution. Though the building is not stylistically cohesive it does demonstrate the evolution of the site, with construction beginning in 1857 (the Victorian period) and continuing on till the 1940’s.

This project included render and concrete repairs to façade, specialised masonry cleaning, paint removal and application of heritage Keim paints, timber conservation and carpentry, emer-clad to parapet horizontal services and caulking to all steel windows.

This project included concrete repairs and replacement of corroded reinforced steel, render repairs, brick replacement, façade cleaning, replacement to all glazing and timber, conservation to windows and applying a 2-coat breathable paint system to the façade.
