Aggregate Industries has supplied its Lytag solution to the £250m redevelopment of 100 Liverpool Street
Aggregate Industries has supplied its Lytag solution to the £250m redevelopment of 100 Liverpool Street. Once complete, this project will provide 520,000 sq ft of office and retail space and a new rooftop terrace offering outstanding views over the city.
For main contractor, Sir Robert McAlpine, a key requirement of the project was to source a concrete solution which would enable more floors to be cast without compromising the dead load of the overall structure.
Lytag from Aggregate Industries can effectively reduce the composite deck concrete slab load by approximately 25 per cent over normal weight control while offering the same level structural performance – enabling 100 Liverpool Street to, literally, reach new heights.
Made from secondary aggregate, Lytag also offers a much more environmentally friendly alternative to standard concrete as thanks to its unique properties, it can help to significantly reduce the amount of material required on a project, along with the associated carbon emission produced in delivery.
In total, Aggregate Industries, working with its specialist London Concrete unit, has supplied 5000m3 of Lytag to the project, with the building featuring an array of sustainable features that complement the significantly reduced carbon footprint. As a result, 100 Liverpool Street is expected to receive an Excellent rating in BREEAM.
