Landlside Repairs
The company repair & manage existing landslides. This can consist of temporary or long -term remediation works. Temporary repairs are often economically viable when there are road closures due to landslides and opening the road to traffic as soon as possible is paramount.

Temporary remediation measures such as clearing the debris and removing any precarious materials from the slope, by explosive blasting or excavation by hand or machine, with our experienced team is usually the initial treatment. Interlocking concrete blocks or fences can also be placed, until a permanent solution can be designed and funded.

Long term solutions can be all, or a combination of the following: soil nailing, ground anchors, geotextile netting, rock catch fencing, concrete beams, mini piled wall, reinforced concrete and stone clad retaining walls. Suitable slopes are often treated with hydro-seeding to encourage vegetation re generation.
