Pavement lights also known as vault lights and sidewalk prisms are mainly used to allow light in to basement areas. First appearing in London in the late 1880s in the form of cast iron frames glazed with cut squares of glass. Plain glass fenestration was quickly superseded by pressed glass lenses, which in turn were succeeded by pressed glass prism lenses designed to transmit as much light as possible.

Glass lenses / glass blocks replacements.
We use reinforced concrete and glass blocks or lenses that are combined not only to produce pavement lights, but also roof lights and floor lights. We are experts in site installations and precast fabrication. We use industry guidelines for all our products to determine loading, thermal, acoustic and fire performance, and compliance with local authority requirements. Slip resistance is less well covered. Experience has proven that the face size limitation for glass lenses (100 mm x 100 mm), imposed by the London authorities in the 1930s, produces acceptable results. Some clients prefer sandblasted lenses and add chromite or carborundum grains in the concrete wearing surface to improve slip resistance.
We use glass lenses with factory-mixed concrete cast in moulds and hand floated to a finish. The default is for the concrete to be left uncoloured, but bespoke colours and textures can be provided. Unglazed units with special surface finishes are available to allow for the addition of in situ surface coverings to match the surrounding area.
The spanning ability of precast units depends on the required loading but spans up to 4.4 m can be achieved with distributed loadings up to 20 kN/m2.
