With views over the University Botanic Garden and at an important junction between the station and the historic core of the city, Botanic House is a seven storey ‘lens shaped’ office building which can provide up to 53,000 square feet of rental space, ideal for the media and biotechnology sectors in Cambridge.
Specialist concrete contractor Knight Build Ltd approached Propump who supplied 50m3 of foamed concrete at a density of 1,000kgs/m3 which was required to complete the infill and to provide support beneath a cantilevered floor slab. With limited headroom to install and compact Type 1, shuttering was erected by Knight Build Ltd and foamed concrete pumped in behind up to the soffit.
Regularly used to fill underground voids, encapsulate pipes and raise floor levels, the easy application of foamed concrete makes it ideal for building and construction sites when space is at a premium. Foamed concrete is pumpable, self-compacting and can mould itself to the shape of any void which in this case resulted in the work being completed in one morning.
When the next phase of works goes ahead, the foamed concrete beneath the slab can be easily excavated to continue the build, as the mix contains only cement, sand and 50% air voids, formed by foam.
Set for completion in 2012, the Botanic House is the first speculative office in the city for twenty years and is on track to serve the continued demand for offices in the centre of Cambridge. Thanks to Propump Engineering, high quality concrete from the UK’s number one foamed concrete specialists has played an integral role in this new development.« Cow Bridge Safe For Cars
