Utilities Case Study

Dubbed ‘London’s Super Sewer’, Thames Tideway Tunnel is the biggest infrastructure project ever undertaken by the UK water industry. Designed to upgrade London’s 150-year-old sewer network, originally built for a population less than half its current size, during heavy rainfall the existing infrastructure was releasing millions of tonnes of untreated raw sewage into the River Thames each year. The new 25 km solution would intercept wastewater and storm water to divert it into plants in a bid to clean up the river.

The only plant of its kind in Coventry, Brinklow Quarry is a dual-purpose site which provides energy to power its operations and supplies the national grid. The quarry required a suitably reinforced concrete slab to site materials used at the facility, capable of withstanding degradation from chemical substances caused from the production of sileage*.

The Thames Road Recycling Centre is located in Dartford and open every day to residents in vans as well as businesses. The centre’s general environment means extreme abrasion is a common occurrence and, due to its busy location, encounters heavy footfall. As a result, the concrete slabs beneath its waste bays have experienced increased damage over time.

Following a successful first phase in 2018, London Power Tunnels 2 (LPT2) is a project to ‘rewire’ south London. The six-year, £1bn scheme will comprise the construction of 32.5km of 3m-diameter tunnels built deep below the road network between Wimbledon and Crayford to carry high voltage electricity cables.

The high performance concrete mixes required for the construction of the Hinkley Point C nuclear power station require precise and robust concrete mix designs and consistent, quality raw materials.

Quattro UK, a multi-disciplined company providing a service to the construction, utilities, demolition and recycling industries, has recently constructed a new plant covering 3-acres in Hayes, West London. The site will contain a cutting-edge ready mix concrete batching and waste disposal facility. It represents an exciting new chapter for the company, as the new plant will lead to an increased production capacity.

Sika® admixtures have been incorporated in the mix design used for the concrete turbine bases that have been constructed at the 60 turbine Crystal Rig II wind farm development near Dunbar in the Scottish Borders.

Sika worked closely with Hanson Concrete to supply 25,000 cubic metres of high workability concrete to a new £450 million natural gas power station that has recently been built at the mouth of the River Usk, near Newport in Gwent.

Built by Carillion Rail for clients West Yorkshire Combined Authority and Network Rail, the new Leeds Station Southern Entrance (LSSE) will enable greater access to one of the busiest stations in the UK and will comprise a concourse deck over the River Aire within a visually eye catching enclosed building. The addition of open link span bridges will provide direct stepped access from this concourse to the east and west banks of the river.
