Oxfordshire Recycling Centre Restored with Teretek®

Areas of the road and car parking area had started to degrade, with holes appearing on the surface, affecting 100m2 of road. The damage was due to a defective drainage system causing the washout of fine soils and the loose made ground to weaken as a result of the excessive water leakage, whilst an abundance of burrowing rats had added to the instability. Previous efforts to resolve the problem were unsuccessful. Concrete solutions were explored but were not effective. The client was seeking a more efficient, longer-term solution that was sustainable, and would not affect either the watercourse or compromise the drainage system. Mainmark was able to provide a non-invasive, cost-effective solution to fill the voids, improve the ground and re-support the road.

The client also required the solution to be long-lasting and environmentally inert, without compromising the drainage systems. The work needed to be completed within a short period, to ensure that normal service at the centre was not affected.

Teretek is also environmentally inert, so Mainmark was able to mitigate any negative impact to the surrounding area that traditional concrete methods would have caused. To complete the reconditioning of the 100m2 of affected road, Mainmark was required to drill 16mm holes in a grid pattern at 1.5m centres, reaching a necessary depth of 1m below the ground. To help ensure that the drainage system below was not affected by the works, drainage monitoring actively took place throughout to process. Mainmark began the work within two weeks of the initial site inspection. The centre was closed to the public on the first day of works, allowing Mainmark’s team to make significant progress. Not only was Mainmark able to remediate the issues thoroughly, but the team worked efficiently, and all work was completed within just two days ensuring that downtime for the centre was kept to a minimum. The road within the site was correctly restored and ready for public use, on time and within budget and the client was extremely pleased with the work.
