Our Solutions

Compounds and Haul roads

Temporary works are necessary for creating a safe and practical construction site, as well as building a more positive relationship with the public and key stakeholders.

But the creation of initial site compounds and haul roads can have a huge impact on resources for contractors, who must take on the associated costs and risks.

As these are short-term measures, understandably, contractors don’t want to spend a large proportion of a project’s time and money on these works – no matter their importance. That's where we can help.

Compounds and haul roads

Keeping costs under control

Accelerate your construction programme

Our geogrid solutions are perfectly positioned to solve these problems. An under-utilised solution, geogrids can reduce the thickness of a haul road or compound, by 50 up to per cent, resulting in substantially reduced construction cost and time.

Along with significant cost reductions, geogrids improve site health and safety, accelerate construction timescales and reduce the project’s overall environmental impact by requiring less use of heavy aggregates to achieve equivalent pavement stability.

This is because when granular particles are compacted over these grids, they partially penetrate and project through the apertures to create a stiff and positive interlock. The load dispersal effect from the interlocking mechanism increases shearing resistance within the aggregates, improving compaction and allowing the granular thickness to be decreased – ultimately reducing construction time, cost and environmental impacts.

Compound

 

The intelligent adoption of geogrids offers two key benefits:

  • Significant upfront savings during construction works
  • Further cost reductions when returning the land to its original use

Supporting tender bids

We’re an advocate of early engagement because if a Wrekin engineering manager is engaged at the tender stage, the impact on the savings to reduce time and money can also assist contractors in winning tenders.

Another benefit of early engagement is that geogrids can be manufactured to the exact width that the contractor needs, suiting the site-specific requirements and creating an even more cost-effective grid. Simply removing a longitudinal overlap in the geogrid layout can save a further 10 per cent in product costs alone. Small changes but big savings are available.

However, all isn’t lost if engagement comes afterwards as savings can still be introduced.

Hinkley Point C Nuclear Power Station haul road
Success stories

Hinkley Point C Nuclear Power Station

The team value engineered a 10km haul road with geogrids in support of contractor J. Murphy & Sons and Balfour Beatty for the first new nuclear power station to be built in the UK in more than 20 years. When complete, Hinkley Point C, in Somerset, will provide low carbon electricity for around six million homes.

The power station will generate a lot of additional electricity and the existing network and infrastructure isn’t sufficient enough to cope. As a result, previous experience had highlighted the need to engage Wrekin’s technical services as a temporary access road was required so construction traffic could efficiently operate on the site where high voltage underground ducts and cables were being installed.
