Poundfield supplies bespoke concrete troughs for National Grid projects
Posted on: February 17th 2015 • Posted in: Poundfield Precast news
Poundfield Precast of Ipswich in Suffolk, one of the UK’s leading manufacturers of concrete retaining wall and related products, has supplied nearly 1000 bespoke concrete trough to Derbyshire based civil engineering and building contractor Alpha Construction.
The troughs will act as drainage and cabling channels at National Grid sites in Canterbury and Burwell where Alpha has contracts to construct flood defence systems able to cope with 100 year flood events.
At the 132/400 kV Burwell substation in Cambridgeshire 435 of the 1220 mm long trough sections are being installed to carry excess rainfall to one of nine pump chambers which will then transfer the water to the outside of a 1 km long, 1.6 m high concrete perimeter wall topped with an electric fence also being built by Alpha.
In order to cast the U-shaped concrete trough sections, Poundfield constructed a set of ten special steel moulds incorporating the necessary profile to enable Alpha to fit GRP cover grills flush with ground level.
Poundfield was chosen as the supplier of the purpose-built troughs following a tender process which highlighted the company as offering the best combination of price, quality and availability.

What are the benefits of precast concrete?
The use of precast concrete has revolutionised the way construction projects are delivered. As the construction industry continually seeks ways to improve speed, cost efficiency and reduce wastage, precast concrete emerges as a compelling solution.
Canvey Island Southern Shoreline Revetment Project
We provided over 1,000 individually reinforced low-carbon precast concrete steps which were manufactured in steel moulds. The units were made using approximately 235m3 of Cemfree Rapid from DB Group Ltd, an alkali-activated cementitious material (AACM) which has 85% lower embodied carbon than 100% OPC (Ordinary Portland Cement) concrete.
