Circular Economy

The Circular Economy Quite simply the circular economy requires three essential elements: Reducing raw material use Reducing waste to landfill Extending product life In construction ground and foundation works the circular economy differs from the traditional linear economy, where primary virgin materials are extracted from the ground, trucked to construction sites, and used, before being […]

Housing on firm foundations

Increases in the cost of buying virgin stone and environmental concerns about the use of recycled crush for site establishment is currently a big concern for the house building sector. The search is on for an alternative more sustainable methodology, and whilst change brings risk, a major housebuilder at a site in Liverpool has discovered […]

Economic Reuse of Contaminated Soils

The exceptional quality of RoadCem in-situ soil stabilisation is well proven in the UK. With the increase in Brownfield development, the same high strength and dynamic stiffness can be achieved with our contamination binder ImmoCem. The following PDF shows how even the worst soils/materials can be cost effectively converted into strong safe building infrastructure. ImmoCem […]

The problem with sewage.

Silo Bases

With the excellent documentary by Paul Whitehouse on TV weekend, which identified problems with effluence entering UK rivers and water courses. The need for water utilities to invest in updating sewage treatment facilities has been truly highlighted. The unique water and acidproof properties of RoadCem in-situ soil stabilisation, together with its crack free leachate proof […]

Improved Car Park Construction Methodology

Car park construction by traditional methods is unsustainable and unnecessarily excessive in carbon emissions. A fit for purpose design utilising just the pre existing site soils can be far more more durable and much lower in long term maintenance costs. RoadCem is a superior road base technology, up to twelve times stiffer than a crushed […]

We love problematic ground/foundations

For difficult groundworks and foundation base problems we at PowerCem are happy to provide sensible sustainable engineered answers. Constructing an 80 tonne per m2 crane platform from wet alluvium in-situ soils, designing a crack free large, shed settlement free subbase in 4m of in-situ PFA. These and similar stabilisation challenges require different thinking and a […]
