Manston Lane Link Road

The project was constructed over the top of existing coal mine workings. Before the new road could be built, extensive drilling and grouting was required to ensure the stability of the underlying ground/mine works. In partnership with WSP, we designed the grouting works and obtained approval from Leeds City Council, as well as engaging a local contractor with extensive knowledge of the area, to successfully complete the project.

Sections of the new link road were over 9 metres above existing ground level.

However, site constraints, including the proximity of new residential and commercial development plots, meant that traditional earth embankment constriction was not possible. To resolve this problem, all new embankments over 3 metres high were designed and constructed using reinforced earth. This involved incorporating geogrid at 500mm intervals vertically to strengthen the embankment slope, achieving a finished slope of 1:1.5 with a largely cohesive material.
