With three key projects under the spotlight, we hear more about Spantherm – the innovative insulated precast concrete ground-floor system which is being adopted by a growing number of housebuilders and developers in GB.

By producing high performance insulated structural concrete units offsite Creagh have redefined the speed of installing a fully insulated ground-floor.  Spantherm is an efficient alternative to labour intensive beam and block installations. It has been utilised at a housing development in Peterborough by NRI Civils who opted for the work to be completed by Creagh’s expert fitting team, requiring no labour from them and saving them time onsite.
Adam Moody, Contracts Manager for NRI Civils said: “We chose Spantherm because one of the things that we are looking for as a business is to improve efficiencies, reduce costs, reduce labour and time onsite and when you’ve got a difficult site, where you’re struggling for storage, that’s exactly where Spantherm is perfect!”
Spantherm’s initial appeal is clear, as a typical floor on a detached house or a pair of semi-detached homes is fitted onsite in less than two hours. Once in place and grouted, the floor achieves its full structural capability within 72 hours, however building activity can commence on perimeter walls within 24 hours. “The team have been absolutely fantastic” adds Adam. “They are always on hand for technical support. We will definitely be using Spantherm again to help our optimum goal of achieving better efficiency and reducing costs and labour times.”
Spantherm has also been used in Nottinghamshire, where a new homes development is being built by Geda Construction. With no additional site works or laying out required, a typical 90m² floor can be installed in just 90 minutes and provides level base without camber for timber frame or block construction.
Installation is not affected by adverse weather conditions and secondary screeds with extended drying times are not required. Spantherm is designed to reduce cold bridging at wall / floor junctions making an important contribution to Part L performance, whilst achieving U-value as low as 0.11W/m2K.
“Geda used Spantherm to push the project along as its one operation that just makes it so much quicker and easier to facilitate onsite,” said Shaun Wormall, Site Manager for Geda. “We are impressed on the installation of the slabs and the time that it saves us onsite. From a site management point of view it’s been really good, Creagh have been very responsive and the production timescales and installation has been quick and painless.  We would definitely use Spantherm again, brilliant product, well-managed and well-run.”
An increasing number of builders in GB are switching from traditional beam and block builds as its significantly reducing labour onsite.  Malcolm Flinn, Director of Stapleford Oaks Ltd in Nottingham states “I chose Spantherm because it’s labour saving, has made life easier for me, its quick, efficient and clean”.
“I would use Spantherm again because the block and beam method takes so many more men and machines on site, and takes a lot longer
to lay.  It also leaves a lot of work for the bricklayers to do at floor level.  With Spantherm we are in and building off it almost straight away” stated Malcolm.
