Reconstructed Stone

Our reconstructed stone finishes can readily be termed as reconstituted stone or cast stone because they all describe the wet-cast concrete we produce with natural aggregates and cementitious binders to resemble the appearance of natural limestones, sandstones and granites.

These finishes are typically specified to match natural Portland and Bath limestones, York sandstones and white Dolomite. The same manufacturing processes can, however, be as readily used to match the colours and surface textures of other stones, with Jura limestone and Cornish granite as further examples, as well as those of other materials, including fired terracotta.

Through our experience in the appropriate selection of crushed stones, gravels, sands and cement with, if necessary, a cement pigment, we are able to offer a comprehensive range of colours for consideration.

Whereas our reconstructed stone finished panels are typically specified with a lightly etched and rubbed surface to match the texture of traditional stone masonry, we are also able to offer a wide choice of other surface textures. These include machine polished and honed finishes as well as a range of coarser grit-blasted, tooled and washed textures.

Whilst our reconstructed stone finished precast concrete units resemble the appearance of natural stone and provide a comparable weather performance, they additionally provide significant quality, cost and programme benefits over traditional masonry. This is because they are generally produced in larger cladding panels than traditional ashlar and are therefore typically:

  • capable of spanning between floor slabs or structural columns, thereby dispensing with the need for any secondary backing structure;
  • Delivered on a just-in-time basis from an off-site store of completed and QA-inspected units to suit site progress, thereby dispensing with the need to double-handle material through temporary on-site storage areas;
  • Installed safely and efficiently without the need for an external mason’s scaffold;
  • Delivered with factory-fixed insulation to enhance their thermal performance;
  • Delivered with off-site framed and glazed window apertures.

The use of large precast cladding panels also enables the structural frame to be enclosed rapidly and efficiently, thereby facilitating an earlier start-on-site by following trades and, consequently, the project’s earlier practical completion. This affords the building owners valuable opportunities to reduce interim funding costs and to realise an earlier return on their overall investment.
