After many years of planning by Southampton Solent Universtiy, Interserve Construction began work in 2014 on the new building known as The Spark design by Scott Brownrigg Architect. This new £21.5M building connects to the existing main University block to create a vast and exciting new atrium.
The site immediately adjacent to the University building in the centre of Southampton is a dramatically sloping site. The Architect designed the building to suit the site with a split level. This meant there was a large retaining wall constructed between the new ground floor and lower ground floor slabs.
Interserve Plc took advantage of the free FIS design service for structural waterproofing and the retaining wall was constructed in accordance with BS8102:2009 using Premcrete Hydrocrete and the Hydrostop BR water bar.
The Premcrete Hydrocrete is a Type B integral waterproofing barrier. It is mixed into the concrete at the concrete plant and the concrete comes to the site with the Premcrete Hydrocrete admixture already mixed into the concrete. This method of waterproofing is fast and easy as it does not require any additional labour or time spent on the waterproofing element of the project in question.
Interserve PLC were also able to take advantage of the free quality control inspections carried out by FIS during the installation phase of the waterproofing. Having knowledgeable technicians available to inspect the installation of the structural waterproofing meant Interserve had peace of mind that the installation was carried out correctly to the design created by FIS which too was in accordance with the British Standard for waterproofing BS8102:2009.
