The Project
The Comber Consortium, a group of housing developers, purchased land near Comber, in County Down, Northern Ireland, intending to build 900 houses, but the plot was adjacent to an unlicensed landfill site that had been used for waste disposal for several years.
The developers wanted to make sure that the environment of the development would be safe for the new residents, many of them being families.
They contacted us, recognising our expertise, to create an innovative plan that would reduce costs and minimise environmental impact.
The Problem
The presence of a landfill site posed a major threat to the nearby River Enler and to public safety. Traditional Dig and Dump methods would have incurred astronomical costs and were dismissed due to the landfill’s proximity to the river.
To address this difficult issue, we developed a comprehensive plan and submitted it to the NIEA (Northern Ireland Environment Agency) for their approval.
Our Innovative Solution
We used LockedIn, our innovative solution, and saved £12,000,000 for our client!
At the heart of our solution, we installed a vertical impermeable liner designed to interface with a natural clay layer and act as a barrier to prevent any contamination from escaping the site and reaching the nearby river.
To improve the containment system, a second horizontal layer was strategically placed on top of the waste and welded to the vertical barrier. This dual-layer approach effectively encapsulated the landfill and isolated it from potential exposure to people and animals.
Additionally, a series of manhole inspection chambers were installed not only to facilitate the extraction of any existing contaminated water but also to enable continuous monitoring of gas levels.
This comprehensive strategy ensured the efficient containment of pollutants, safeguarding the environment and people’s well-being.
