Geotechnical Repairs

High Peak Access Ltd were commissioned to undertake inspection and remedial works on a previously installed rockfall protection system. During the inspection, it was identified that the existing geotechnical netting—installed by another contractor—did not meet the required anchorage specification, with an insufficient number of rock anchors present to adequately secure the system. In addition, the lower retaining cable had deteriorated and required repair to ensure the netting remained fully effective in containing loose material and protecting the area below.

Following a detailed site assessment, High Peak Access developed a bespoke repair strategy designed to safely restore the integrity of the rockfall protection system while minimising disruption to the surrounding environment. The works involved the installation of additional anchors and the repair and re-tensioning of the bottom support cable to improve the overall stability and performance of the netting.

To carry out the works efficiently and safely on the challenging terrain, HPA deployed its Ripamonti EX121 SD180 drill rig in conjunction with a Komatsu long-reach excavator and in-house operator. This specialist equipment enabled the team to access difficult areas of the cliff face.

Working to the agreed methodology, the team successfully completed the repairs, securing the netting firmly against the rock face and reinstating the system's ability to mitigate rockfall risks.

The completed works extended the operational lifespan of the existing installation and ensured the cliff face remained protected, providing a cost-effective solution without the need for a full netting replacement.

Through careful planning, specialist plant deployment, and experienced site personnel, High Peak Access delivered the project safely, efficiently, and to the required geotechnical standards.
